ABSTRACT. Bank rankings are one of the ways to rate the bank system and to create 

competitive advantages, which have emerged as the central issue and considered as one of 

the most important organizational innovation. This research is objective to explore and to 

demonstrate utility of Analytic Hierarchy Process (AHP) application in banking for the 

purpose of proposing suitable model for partners evaluation and selecting banking strategic 

alliances in Vietnam. The AHP is applied to examine what criteria should be encompassed 

in evaluating and examining the importance weightings of influential criteria when ranking 

the bank system. In this study, a short review of literature regarding application AHP in 

banking decision-making is presented, focusing on partner evaluation criteria and methods 

to propose model for partner evaluation and selecting strategic banking for the current study. 

After a long process of calculation based on AHP, I have come up with the final rankings 

according expert’s interview: ACB’s percentages have change widely from each sub-

criterion; finally it gets 12.98% at the top of the list. Coming very closely downwards are 

DAB, SeAbank etc., at the bottom of the rankings is SGB at 7.41%. By this paper, author 

would contribute to the ranking process of the banking system, in general, and the special 

case of Vietnamese banking a very modern model to apply, then to choose the right alliance 

for further cooperation, not only for banking system but it can be applied for a lot of 

industries.

I. INTRODUCTION 

1.1 Research Background 

Bank rankings are one of the ways to rate the bank system and to create competitive 

advantages, which have emerged as the central issue and considered as one of the most 

important organizational innovation. The facts of successful bank rankings demonstrate 

that choosing a right cooperative partner possibly decides the fate of the majority of 

strategic alliances [1]. 

In the new era of banking, bank ranking formation has been growing among the financial 

industry during the last decades [2]. Bank rankings often include units like mutual fund 

managing companies, asset management companies, securities brokerages and corporate 

finance companies. Financial mergers and financial rankings can bring some advantages 

in terms of improving financial structures, and promoting the operating performance of 

financial organizations [3]. In the context of related studies focusing on Vietnamese 

industries are increasing; the author explores that studies that examine the bank rankings 

formation between banks are still rare although synergies between banking are so 

significant ([4],[5]) 

The growth of banking system increases in parallel with the monetization degree of 

markets; thus the development in the banking sector mutually and deeply affects the other 

sectors of the economy, particularly real economy [6].  Over the past two decades, the 

Vietnamese government has undertaken a series of reforms to strengthen and modernize 

this sector in order to adapt to the rising household incomes and an increasing demand for 

retail banking services, which resulted from rapid economic growth [7]. Soon after the 

Vietnamese government lifted its ban on the establishment of new banks in the years 2000s, 

numerous new banks began operations. In 2006, the government responded to the 

excessive number of banks and this leads to the competition for capital among banks. There 

are various forms of competitive pressure, such as retaining new customers, providing new 

financial services and holding available businesses [8].  

Some methods like mergers and alliance formation have now become an emergent issue 

for Vietnamese banks and some banks’ top managers are trying to adopt these philosophies 

to improve their competitive advantage ([9],[10]).

Bank rankings of financial organizations are closely linked to organizational performance, 

government policy, shareholder rights and customer satisfaction. It is essential for financial 

organizations to select their strategies carefully. Factors requiring consideration include 

various internal, external, qualitative and quantitative attributes, indicating that the 

selected problem is an analytical hierarchy issue [11]. A well-known approach that can 

effectively deal with this problem is the analytic hierarchy process (AHP) [12]. The AHP 

methodology involves separating a complex decision issue into elemental problems to 

establish a hierarchical model. When the decision problem is divided into smaller 

constituent parts in a hierarchy, pair-wise comparisons of the relative importance of 

elements are conducted at each level to establish a set of priorities.  

AHP is widely employed in diverse fields, especially growing its effectiveness among the 

financial industry ([13], [14], [15]). For example, Korhonen and Voutilainen (2006) [16] 

studied alternative alliances between banks and insurance companies. Six different 

possible structure models for such alliances and nine criteria are used to evaluate the 

models. The use of the AHP focused the discussions on pair-wise comparisons. Based on 

the evaluations of the panel, the alternatives financial conglomerate and cross-selling 

agreement, and no overlapping service channels are most preferred. Seçme et al. (2009) [17] 

proposed a fuzzy multi-criteria decision model to evaluate the performances of banks. The 

largest five commercial banks of Turkish banking sector are examined and these banks are 

evaluated in terms of several financial and non-financial indicators. Fuzzy Analytic 

Hierarchy Process (FAHP) and Technique for Order Performance by Similarity to Ideal 

Solution (TOPSIS) methods are integrated in the proposed model. After the weights for a 

number of criteria are determined based on the opinions of experts using the FAHP method, 

these weights is input to the TOPSIS method to rank the banks. The results show that not 

only financial performance but also non-financial performance should be taken into account in 

a competitive environment. 

Financial organizations have been globally studied, but few of these studies have examined 

the strategies used by banks in Vietnam for making decisions regarding bank rankings. 

Basing on the successful experiences of rankings which raises some rules for choosing 

strategic alliance partners, and gives a description of how to choose the best partner with 

AHP, in this paper we have studied the bank rankings between 10 top Vietnamese banks 



Int. J. Anal. Appl. 17 (1) (2019) 135 

 

 

that are already on the financial industry for the purpose of proposinga suitable model for 

partner evaluation and selecting banking strategic alliance for any financial organizations. 

The main objective of this study is applying AHP to examine what criteria should be 

encompassed in evaluating and examining the importance weightings of influential criteria 

when ranking the bank system. 

1.2 Research Objectives and Implications 

Our research objectives are to explore and to demonstrate utility of AHP application in 

banking for the purpose of proposing suitable model for partners evaluation and selecting 

banking strategic alliances in Vietnam. We want to apply AHP to examine what criteria 

should be encompassed in evaluating and examining the importance weightings of 

influential criteria when ranking the bank system. In this study, a short review of literature 

regarding application AHP in banking decision-making is presented, focusing on partner 

evaluation criteria and methods to propose model for partner evaluation and selecting 

strategic banking for the current study. Analytic Hierarchy Process (AHP) application in 

banking sector is growing most recently and has been seen as a high potential decision 

support tool in banking sector in the days to come. The use of AHP as a decision support 

tool is appreciated and interested by the author. This study reviews application of AHP in 

the finance sector with specific reference to banking.  

Bank ranking is one of the most complex and ill-structured tasks faced by banks. In 

deriving these strategies bankers usually try to achieve multiple, and sometimes conflicting 

objectives such as profitability, growth, liquidity, and market share subject to constraints 

on credit and exchange risks and regulatory requirements [18]. However, it is safe to 

assume that the AHP methodology can be applied to other complex and ill-defined 

strategic issues faced by other banking institutions because when compared with existing 

techniques on the one hand, and with qualitative managerial judgment on the other hand, 

the AHP provides a useful, simple and powerful tool for dealing with strategic planning 

in banking [19]. 

As mentioned above, the alliance with a highly regarded financial services institution may 

give financial organizations and cooperative industries an opportunity to build a suitable 

strategic relationship. The proposed strategy may also attract the concerns and preferences 



Int. J. Anal. Appl. 17 (1) (2019) 136 

 

 

of bank stakeholders. The results of this study provide a valuable reference for bank 

administrators. 

This current study contributes to the two elements of practical application of AHP method 

and academic application of the field evaluating and then to form suitable business strategy 

for a financial institution in a developing country. By presenting and applying AHP to 

researches and analyzing the advantages and disadvantages of this method, it provides top 

managers in related areas with the ability to integrate the multi-attribute preferences of 

consumers using a hierarchical model to determine the bank's relative position in the 

marketplace. The suitability of AHP in examining bank selection by consumers for 

managerial decision making is demonstrated using an empirical analysis in a major metro-

Politian area. Implications of the findings of this analysis for strategic planning in the areas 

of marketing mix and organizational characteristics of a bank are explored. Suggestions for 

application of AHP to other areas of financial services management are included. 

The research method wasapplied in this research includes:  

(1) Research discovery: to explore preliminary research issues that need as well as claims 

the research problem.  

(2) Method of describing and comparing or the method of decision-making.  

(3) Method of intergrated analysis towards the problem of assessing the quality and 

selecting suitable model for partner evaluation and bank rankings in Vietnam. 

(4) Qualitative amd expert methods: to review evaluation criteria for selecting suitable 

model for partner evaluation and bank rankings in Vietnam. 

(5) Quantitative research method: Collecting information and data in quantitative form. 

This method is used in the process of applying AHP to evaluate and bank rankings in 

Vietnam. 

(6) Data are collected through the process of surveying and interviewing representatives 

of banks chief executives, managers and staff;  practicing outdoor activities; company 

file documents; journal and newspapers.

II. LITERATURE REVIEW 

2.1 Basic Concepts 

The application of AHP in banking sector is growing most recently, and it is being 

combined with conventional bank evaluation parameters in this study. First, the main and 

sub criteria for the evaluation of banks performance are discussed along with the 

alternative Banks. Then the literature for the selection of banks through its performance is 

given. 

Decision-Making Problem 

The availability of more choices makes the process of decision making complicated. Thus 

it becomes very arduous task to select from the array of choices. The problem becomes even 

more gigantic in case of emerging a fierce competition among banks. Decision making 

process thus becomes a complicated phenomenon when the best alliance can help bank 

increase competitive advantage and survive through competition. Many factors are 

involved in choosing a partner thus selection of best banks to form alliances will fall into 

the category of multi-criteria analysis problem. 

2.2 Decision-Making Using the Analytic Hierarchy Process 

In this section, we will describe problem with the Analytic Hierarchy Process which 

include its concept, functions, basic scales, practical applications, and illustrative examples. 

Finally, we analyze the advantages and limitations of AHP method. 

2.2.1 Concepts 

In previous studies, AHP was implemented to help decision maker to choose the best 

solution among several alternatives across multiple criteria. Decision-making is related to 

the level of intelligence, wisdom and creativity to satisfy basic needs, to have better 

selective choices and to increase productivity for the enterprises. Evaluating a decision 

requires several considerations such as the benefits derived from making the right decision, 

the costs, the risks, and losses resulting from the actions taken if the wrong decision is made. 

Decision-making methods range from variety of choices in order to use more suitable 

decision-making tools. In the 1970s, Thomas Saaty developed AHP as a way of making 

decision dealing with weapons tradeoffs, resource and asset allocation when he was a 



Int. J. Anal. Appl. 17 (1) (2019) 138 

 

 

professor at the Wharton School of Business and a consultant with the Arms Control 

Disarmament Agency.  

2.2.2 Function of AHP 

AHP is a time-tested method that has been used to decide for many successful businesses 

worldwide. It uses the judgments of decision makers to form a decomposition of problems 

into hierarchies. Problem complexity is represented by the number of levels in the 

hierarchy which combine with the decision-makers model of the problem to be solved [12]. 

The hierarchy, as shown in figure 1, is used to derive ratio-scaled measures for decision 

alternatives and the relative value that alternatives have against organizational goals 

(customer satisfaction, product/service, financial, human resource, and organizational 

effectiveness) and project risks.  

AHP uses matrix algebra to sort out factors to arrive at a mathematically optimal solution 

and derives ratio scales from paired comparisons of factors and choice options. AHP 

consists of four steps [20]. In the first step, the author defines the problem and state the 

goal or objective. In part two, the criteria or factors that influence the goal are made clear. 

In this step, the structure of these factors into levels and sublevels are also formed. In part 

three, the author uses paired comparisons of each factor with respect to each other that 

forms a comparison matrix with calculated weights, ranked eigen values, and consistency 

measures. In the final step, synthesize the ranks of alternatives until the final choice is made.

2.2.3 AHP basic scales 

The paired comparison scales between the comparison pair (aij) of two items (item i and 

item j) is as follows:  

(itemi) 9-8-7-6-5-4-3-2-1-2-3-4-5-6-7-8-9 (item j) 

 

The preference scale for pair-wise comparisons of two items ranges from the maximum 

value 9 to 1/9 (0.111 in decimal from). Let aij represent the comparison between item-i (left) 

and item-j (right). If item-i is 5 times (strong importance) more important than item-j for a 

given criteria or product, then the comparison aji = 1/aij = 1/5 (0.200) or the reciprocal 

value for the paired comparison between both items.  

After the comparison matrix is formed, AHP terminates by computing an eigenvector (also 

called a priority vector) that represents the relative ranking of importance (or preference) 

attached to the criteria or objects being compared. The largest eigenvalue provides a 

measure of consistency. Consistency is a matrix algebraic property of cardinal transitivity 

where the equality a(ij) = 1/a(ji) = a(ji)-1, and a(ij) = a(ik) a(kj) for any index i, j, k. 

Inconsistencies arise if the transitive property is not satisfied as determined when the 

largest eigen value from the comparison matrix far exceeds the number of items being 

compared. 

The AHP preference scale shows in Table 2.1 to form the comparison matrices  [12]. 

Table 2.1: Preferences made on 1-9 scale 

AHP Scale of Importance 

for comparison pair (Aij) 
Numeric Rating Reciprocal (decimal) 

Extreme Importance 9 1/9 (0.111) 

Very strong to extremely 8 1/8 (0.125) 

Very strong importance 7 1/7 (0.143) 

Strongly to very strong 6 1/6 (0.167) 

Strong Importance 5 1/5(0.200) 

Moderately to Strong 4 1/4(0.250) 

Moderate Importance 3 1/3(0.333) 

Equally to Moderately 2 1.2(0.500) 

Equal Importance 1 1(1.000)

The Geometric Mean is an alternative measure of the Priority and was formed by taking 

the n-th root of the product matrix of row elements divided by the column sum of row 

geometric means. The Geometric Mean agrees closely with the Priority.  

Lambdamax (4.2385) is an eigen value scalar that solved the characteristic equation of the 

input comparison matrix. Ideally, the Lambdamax value should equal the number of 

factors in the comparison (n=4) for total consistency.  

The consistency index (ci) measures the degree of logical consistency among pair-wise 

comparisons. The random index (ri) is the average CI value of randomly-generated 

comparison matrices using Saaty’s preference scale (Table 3) sorted by the number of items 

being considered.  If  |CI| <0.05, it shows good consistency of pair-wise comparisons. 

If |CI|>0.05 1 means the pair-wise comparison should be revised.  

CI =
(λ max − n)

(n − 1)
 

Consistency ratio (cr) indicates the amount of allowed inconsistency (0.10 or 10%). Higher 

numbers mean the comparisons are less consistent. Smaller numbers mean comparisons 

are more consistent. CRs above 0.1 means the pair-wise comparison should be revisited or 

revised.  

𝐶𝑅 =
|CI|

RI
 

Random Index (RI) is the average value of CI for random matrices using the Saaty scale 

obtained by Forman (Geoff, 2004). To determine the goodness of CI, AHP compares it by 

Random Index (RI), and the result is what we call Consistency Ratio (CR). Random Index 

is the Consistency Index of a randomly generated reciprocal matrix from the scale 1 to 9 

(Geoff, 2004). Table 2.4 below shows the values R.I. sorted out by order 1 to 15 matrix. The 

CR can then be calculated.

III. METHODOLOGY  

3.1 Selection of Banks for the Purpose of the Study 

In this paper expert opinion is collected for the generation of criteria and sub criteria 

weights through a questionnaire containing fuzzy pair wise comparisons using linguistic 

terms. Further the alternative Banks are given weights based on the size of the stock market. 

Ten banks were selected purposively for the purpose of the study. The banks selected for 

the purpose for the study are traded in Hanoi and Ho Chi Minh City stock markets whose 

selection of the index set is based on the following criteria, which are referenced from 

thebanker.com – 500 banking brands in 2014: 

1. Company's market capitalization rank in the universe should be less than 500 

2. Company's turnover rank in the universe should be less than 500 

3. Company's trading frequency should be at least 90% in the last six months. 

4. Company should have a positive Net-worth. 

5. A company that comes out with an Initial Public Offering (IPO) will be eligible for inclusion in 

the index, if it fulfills the normal eligibility criteria for the index for a 3 month period instead of a 6 

month period. 

 

The banks selected for the purpose of the study are BIDV, VietinBank, ACB, SacomBank, 

DAB, HDBank, SeABank, SGB, MBB, and SHB (listed in Table 3.1). Moreover, the author 

has many friends who are current working in the banking system. The banks are selected 

to administer survey questionnaires are SGB (Ho Chi Minh City branch); DAB (Ho Chi 

Minh City branch); and Vietcombank (Ho Chi Minh City branch). Customers who have 

high frequent bank transactions were also invited to participate in this study. The details 

about participants who are both experts and customers are listed in Table 3.4.

3.2 Evaluation Criteria and Sub-criteria 

The first step of the proposed model is to determine all the important criteria and their 

relationship with the decision variables in the form of a hierarchy. This step is crucial 

because the selected criteria can influence the final choice. 

These questions are always raised whenever we have contacts with the people we want to 

survey on. And these are asked by short interviews. This step is crucial because it can raise 

that the data used in this study is provided and confirmed by the experts in the field of 

banking and customers using banking services. 

1. Are you an expert in this field, working in it daily? 

2. Do you work in this field occasionally? 

3. Are you knowledgeable about this field through occasional professional reading? 

4. Would you classify yourself as an informed layman? 

5. Are you uninformed about this field? 



Int. J. Anal. Appl. 17 (1) (2019) 143 

 

 

The first round questionnaire was implemented in November 4th to November 8th 2014. 

In the first round, the panellists were asked to suggest new or current criteria in the job of 

ranking banks. Many new suggestions were received. They were asked to review the list 

below and provide their judgments about their likelihood and impacts in the table 3.2. 

Then these factors are arranged into the 5 main criteria including: Income, Expenditure, 

Staff, Security and ATM services.

After we have 5 main criteria, the experts were asked to list down sub-criteria of each main 

criterion. This process is called second round selection, which are listed in the following 

tables. This process will be taken placed right after we summarized the main criteria, which 

was during the period of 13 November to 16 November, 2014. Moreover, they are also 

asked to fulfil one more point before we go the survey of AHP to do the ranking of the field. 

From table 3.13, the author takes only the parameters which are evaluated by experts and

3.4 The Process to Select the Right Target of the AHP Method 

This section presents the process according to the method of calculation process of AHP. 

Start with a hierarchical diagram level 5 main criteria governing the evaluation of the bank 

industry (see figure 3.1). This matrix shows the relationship between the main criteria 

according to the scale of the AHP. Based on this table can determine the correlation 

between the level of importance of the variables. 

The whole process of this study is present in figure 3.2. There are 9 phases to run, select 

and analysis based on the applied method – AHP.

Phase 1: data collection  

Delphi method: 1st round (14-18th November, 2014); 2nd round (13-16 December, 2014) 

AHP questionnaire: 18-25th January, 2015 

The process of data collection is carried out according to the method of experts: 

Step 1: based on assessment model has been developed, author use pilot interviews 

to experts to verify the appropriateness of the 6 main criteria KPI in level one and 16 in 

level two, together with confirming the identification actual business reality. 

Step 2: based on the results of step 1 to adjust the model and building 

surveys/questionnaires. 

Step 3: surveys combined with direct interviews to each expert. At the request should 

have over 30 experts but by the actual situation should be reduced to 26experts. Moreover, 

customers who have used banking services for years are also involved in this study. 

Step 4: collect other data through reports and documents related 

Phase 2: a batch process data 

After collecting a full range of primary data through surveys and interviews with experts’ 

opinions, together with the secondary data through reports: financial, production, 

performance, etc., these data are processed through the steps of a batch filtering criteria of 

the main criteria, then filter by the KPI side, verify authenticity versus reality and reliability 

of the data. 

Phase 3: sorting data and KPI main criteria of the model  

A batch is classified according to six main criteria, and then they are further classified 

according to 16 KPI sub-criteria of the model 

Phase 4: enter the model created by Excel  

Excel is as a DSS generator: it is used to construct the computational model,and to handle 

data for each KPI fitting main criteria in the evaluation model. After setup is complete, the 

DSS model is to conduct verification of scale, the formula to ensure the appropriateness 

and scientific. Then, we enter the processed and classified data prior to the DSS model to 

prepare for phase 5. 

 



Int. J. Anal. Appl. 17 (1) (2019) 151 

 

 

Phase 5: data processing secondly 

After entering the data, we conducted calculations, check, and then evaluate for each scale 

suitably.  

Phase 6: scale transition to AHP  

AHP method using pair wise comparison scale separately on a scale from one to nine, so 

after the calculation results ranking suppliers, we must make the transition scales 

corresponding to the AHP under the own standards of this method. This stage aims to 

prepare for entering data into the matrix of pair wise comparison at a later stage. 

Phase 7: Creating and Putting Data into AHP matrix table 

The first boot after the application of the AHP hierarchy drawing assessment model, enter 

the criteria in a level floor, then to the sub-criteria floor level to level two to n, and finally 

enter choice alternatives. Then enter the data were processed in each pair wise comparison 

matrices, respectively. Inside is under processing data has been entered into the pair wise 

comparison matrix between the six main criteria in the evaluation model. 

Phase 8: Calculating Matrix by Using Set-up Formulas in Excel 

After we have the AHP tables, we use Excel as a tool to calculate these matrices. Inputting 

all the data surveyed is a careful step to do to make sure that the calculation is accurate. 

Phase 9: Finalizing and Reporting Results 

This is the final step of the process. We just see and report results. This will be illustrated 

carefully in chapter 4. 

Once the hierarchy is established, the fuzzy pair wise comparison takes place. The experts 

compare all the criteria on the same level of the hierarchy. A pair wise comparison is 

performed by using Fuzzy linguistic terms in the scale of 0 – 10 described by the Triangular 

Fuzzy Numbers in the Table 1.1. In Buckley's method, the element of the negative judgment 

is treated as an inverse and reversed order of the fuzzy number of the corresponding 

positive judgment. Thus it requires not only a rigorous manipulation in the construction of 

reciprocal matrix but also due to transitivity the result becomes inconsistent. Again to 

reflect pessimistic, most likely and optimistic decision making environment, triangular 

fuzzy numbers with minimum value, most plausible value & maximum value are 

considered.

𝐴 = (
1 𝑎12 𝑎1𝑛

𝑎21 1 𝑎2𝑛
𝑎31 𝑎32 𝑎3𝑛

) 

 

To simplify the calculation of element weight the fuzzy pair wise comparison matrix is 

broken into crisp matrices where the crisp matrices are formed by taking the minimum 

values, most plausible values & maximum values from the triangular fuzzy numbers, 

which were mentioned in chapter 2. 

IV. RESULTS 

4.1 Setting Stage 

In this chapter, the whole process of calculation will be analyzed. Then the results of each 

weight of the alternatives will be illustrated. And finally, the final results of selection the 

right instant coffee supplier will be displayed according to experts’ interview. 

Comparable data are collected by the method of survey experts through interviews and 

direct the relevant agencies. Homogeneity index (incon) 0.05 of AHP is satisfactory. The 

main criteria are comparable bond correlation pairs separate to produce detailed data 

calculations. The tables above are typical illustrations for pair wised comparison matrices 

need to enter the data set gathered from interviews of experts in the relevant industry. 

There are 23 matrices developed to cater for the processing of the data model. And 

following authors quote a matrix in which to further illustrate this problem.

Table 4.1 gives a typical example of how to input interviewed data into the matrix of AHP. 

For example, Income is 2 times important than Expenditure, then Expenditure is equal 0.5 

of Income.

After doing calculation from table 4.1, each cell is done by choice divided to the cell total 

value of the matrix. For example, we have 0.3243 = 1/3.0833. Then, the weight is the 

average of each row, which is total divided to the number of criteria. 

This weight will be used to calculated the second phase of the matrix, which is illustrated 

in the below table.

From table 4.1 and table 4.3, we have each criterion value calculation. Then, we come up 

with SUM and SUM/weight. SUM/Weight is an important element to calculation lambda

From table 4.3, we have the weight of Income is 33.7% over 100% of 5 main criteria (1-level). 

Then, we have the weight of each sub-criterion from table 4.4. Here, we come to the table 

showing the percentage of sub-criterion over the whole picture to choose the supplier.

According experts and customers surveyed in this study, the INCOMES and 

SECURITY of the bank are the highly important factors at 33.7% and 33.6%. ATM 

services are at lowest percentage (8.4%). This will be discussed in the chapter 5 in which 

the author would like to make conclusions and research suggestions. 

Under their main criteria, the sub-criteria are calculated their global weights. For 

example, the main criteria of INVESTMENT is INCOME (at 33.7%) and the 

INVESTMENT local weight is at 66.1% so its global weight is 22.7% (=66.1%*33.7%).

4.3 The Final Rankings 

After respectively calculating, analysis and evaluating of suppliers through each sub-

criterion of six main criteria in Balanced Scorecard of AHP model, we have been solving 

the second floor of AHP hierarchy. And this is the final calculation results which are 

obtained after running the data through the two floors of the criteria assessment model 

according to the method of AHP. The percentages are of banks shown in the table. 

Based on these values, we can rank as well as further analysis of the selected 

alternatives. Plus we can evaluate each bank. Besides, to compare the degree of 

difference between the alternatives, any financial organizations can make a decision in 

choosing the best suppliers and the most suitable. 

 

Table 4. 10: The Final Rankings 

Ranking Banks Global Weight 

1 ACB 12.98% 

2 DAB 12.11% 

3 SeABank 11.54% 

4 SacomBank 10.74% 

5 BIDV 10.38% 

6 SHB 9.66% 

7 VietinBank 9.29% 

8 HDBank 8.35% 

9 MBB 7.52% 

10 SGB 7.41% 

 

Table 4.11 summarizes the final results in evaluating and rankings, which are 

previously detailed in table 4.10 after applying AHP method. We can see the changes 

of percentage of banks by criteria. ACB’s percentages have change widely from each 

sub-criterion; finally it gets 12.98% at the top of the list. Coming very closely 

downwards are DAB, SeAbank etc., at the bottom of the table is SGB at 7.41%. 

 

This chapter discusses data analysis and the results of the current study. We first 

conduct setting to categorize the focused characteristics and steps towards this study 

will take place. Then, the selection analysis of each supplier is summarized in detail.

The purpose is to find the final rankings of Vietnamese banking system according to 

the survey results from experts. From that, the final rankings were set up to get the 

results, which can be further discussed in the next chapter. 

V. CONCLUSIONS 

5.1 Discussions and Managerial Implications 

This final chapter will comment on the results achieved, pointed out the conclusions 

and recommendations presented by the author, and the limitations encountered. On 

the other hand, the author gives a number of research directions for the development 

of the subject in the future and expands the application of AHP in practice. 

In fact, many scholars and experts have already studied the related subjects of 

measurement performance, which includes the meaning of performance management, 

its elements and contents, and the measurement index ([21], [22],[23], [24]). On the 

contrary, the study of performance management is still not sufficient so far. In this 

study, the author conceder corporate intangible value and clearly understand 

performance management ability of each Vietnamese banking system by AHP. Besides, 

performance management is the key factor of high-tech companies’ operation outcome, 

the author hopes those results can offer performance management as reference for the 

academia and professionals. 

The results from the model are evaluated using the method of AHP quantification. AHP 

can compare the tiniest differences between providers through the numbers, charts and 

graphs. The results of detailed calculations to each level of the ladder system provide 

multi-faceted perspective. Strong ability to synthesize the components of the hierarchy 

and logic algorithms are not too complicated, but also help managers can examine each 

aspect and see the overview are all issues are considered. 

In an organization that has always existed three important lines: The first line of 

communication throughout the system, the second is financial flows, also known 

simply as cash flow, and finally the material flow. Purchasing is one of the important 

tasks of the business because it is responsible for the physical input line of the 

organization. Increasing awareness of purchasing should be advanced position and its 

role in the enterprise is increasing. Most organizations now recognize closely related to 

purchasing strategy should the company access to parts purchasing increasingly more 

difficult. Information security requirements for these departments are increasingly 

stringent.

The process of evaluation and selection of suppliers has long held bias in a qualitative 

sense, dependent on experience and emotions of those who have related responsibilities. 

Therefore, it is necessary to apply the typical methods such as quantitative analysis of 

this process - AHP presented in this study. With the aim of increasing the 

computational content of the evaluation process suppliers, especially the comparison 

of suppliers in the same industry as AHP has shown. This enables the analysis of all the 

providers and more scientific. Thus, this thesis would help the facility managers ensure 

objectivity to the reasonable decision. 

Through the application of analytical methods to process steps or methods to compare 

providers evaluate other qualitative factors could improve and contribute to the 

financial organizations which then in the future they can apply and expand their 

business. 

Moreover, the main evaluation criteria and sub-criteria have been quantified to ensure 

that most of the stages in the purchasing process. When evaluating partners is well 

supplied, all stages in the process of purchasing them achieve flawless collaboration. 

5.2 Limitations and Future Research 

This thesis utilizes the interview method access the expert groups and questionnaire 

surveys with data collected to be slightly biased and subjective experience. 

The data primarily comes from the documents and reports out there, not yet 

homogeneous. Years missing data so that comparisons between providers and become 

limp. 

The process measurement data collected are processed and applied scales also 

unsettled. The comparison between the criteria in suppliers has not yet met the 

stringent requirements of the equivalent. The transformation scales to scales AHP has 

many limitations. 

It is possible to dig more theoretical model further evaluation. There are many criteria 

that can be used for model assessment. Every type of business and every business will 

have specific criteria in accordance with the individual's typical enterprise. It is 

important to note build an assessment model provider in accordance with industry 

characteristics and distinctions of the business. It should be tried to reach deep to the 

data source to the enterprise purchasing the thesis topic under direction of this form of 

anonymous real close to reality than now.

Finally, the different measures provide distinct perspectives which help us have deeper 

conclusion about the association between working capital management and firm 

performance. Therefore, future researches should fill this research gap by generalizing 

findings using larger sample size in order to have more general, imperative vision as 

well as solutions for enterprises in many other fields. More measures of firm 

performance management as well as measurement performance components should be 

applied in future researches have better evaluation.  

5.3 Conclusions 

By this thesis, author would contribute to the banking system by providing the 

evaluating by the discussed criteria and sub-criteria. The research results suggest that 

performance management, which invest technology, improving quality, and structural 

management, is one of the main sources of competitive advantage for firms. This study 

argues that performance management is a necessary strategic tool for use against 

competitors. The emphasis on intellectual capital can help firms implement new 

initiatives for enhancing their performance. That means the technology on the security 

should be focused. Moreover, many experts and customers rate the INCOMES of a bank 

is really important, so that banks should build up the structural and marketing 

management to boost the IMCOMES. Other factors, including ATM and STAFF, are 

chosen at the certain level to evaluate a bank.
