Abstract. Multi-criteria decision-making (MCDM) techniques are widely used in 
selecting the best alternative amongst a number of alternatives. In this paper, the quality 
of the operation of seven newly-established Indian institutes of technology (IITs) in India 
is analyzed by using the modified Simple Additive Weighting (SAW) method to 
subsequently rank them. The entropy method is used to determine the weights 
associated with the criteria under study. The criteria considered for the analysis are as 
follows: the percentage of vacant seats during student intake, the strength of the faculty, 
research publications, the sponsored research fund, the student success index, the 
number of the students who are employed through the placement cell, the number of the 
students who opted for higher studies and the number of PhDs awarded, respectively. 
The performance of this method is further compared with the MOORA, TOPSIS and 
COPRAS methods; the results obtained are found to corroborate well with those obtained 
by the modified approach. Furthermore, a sensitivity analysis is conducted by changing 
the criteria weights so as to establish the stability of the ranking obtained. IIT G is 
considered to have a better performance in all the methods than the other IITs do. This 
research has shown that the modified SAW is a useful and reliable tool for normal 
decision-making.

1. Introduction:  

Indian Institutes of Technology (IITs), namely Kharagpur IIT, Bombay IIT, Madras 
IIT, Kanpur IIT, Delhi IIT, Guwahati IIT, Roorkee IIT, etc. are considered to be the most 
prestigious engineering and technology institutions in India. All the IITs were 
established by a number of the scientists, technologists and engineers of the highest 
caliber who would engage themselves in research, design and development in order 
to help build the nation towards self-reliance in its technological needs. After that, nine

more IITs were established, namely Bhubaneswar IIT, Gandhinagar IIT, Hyderabad 
IIT, Jodhpur IIT, Patna IIT, Ropar IIT, Indore IIT, Mandi IIT and Varanasi IIT. There are 
also the seven most recently established IITs, namely: Palakkad IIT, Tirupati IIT, 
Dhanbad IIT, Bhilai IIT, Goa IIT, Jammu IIT and Dharwad IIT. All the IITs in India are 
also amongst the most heavily funded educational institutions in the country.  

As high-performing institutions, IITs are included in several studies on the 
institutional ranking based on research performance. In those papers, however, IITs 
were mostly used as the benchmark institute with several other governmental and 
privately-owned institutions. In the past, researchers tried to identify top Indian 
engineering and technological institutions according to their research performance, 
including all the seven older IITs in the list, based on which they found all the seven 
older IITs to rank the highest on the list (Prathap & Gupta (2009), Nishy et al. (2012), 
Prathap (2013, 2014)]. For the ranking of the institutes, multi-criteria decision-
making (MCDM) techniques were widely employed, because they involve multiple 
conflicting criteria in decision- making. Tyagi et al., 2009, evaluated the performance 
efficiencies of the 19 academic departments of the Roorkee Indian Institute of 
Technology (IIT) by applying the DEA technique. Das et al., 2010, used the fuzzy 
Analytic Hierarchy Process (AHP) method for the purpose of evaluating the 
performance of six institutions. Das et al., 2012, also carried out a comparative 
evaluation of seven Indian institutes of technology (IITs) by using the fuzzy AHP and 
COPRAS methods. Again, Das et al., 2013, presented a combined SOWIA-MOORA 
approach so as to evaluate the performances of Indian technical institutions. It was 
observed that the performance of two IITs would need a considerable improvement.  
The research studies that have been conducted so far have included seven older IITs 
only for the purpose of a comparative analysis according to different performance 
criteria. The performance analyses of newer IITs have not been made a mention of in 
the literature. In the present study, a total of seven newly-established IITs have been 
taken into consideration for analysis. In this work, eight criteria have been considered 
for the analysis, namely: vacant seats (in %) (VS), the strength of the faculty in respect 
of PhDs (FS), the number of the research papers (RP) published in a Scopus-indexed 
journal in the last three years, the sponsored research fund (RF) (in lacs), the student 
success index (SS) or the pass percentage, the number of the students who are 
employed through the placement cell (E), the number of the students who opted for 
higher studies (HS) and the number of the PhD awarded (PA).  Therefore, the present 
study contains a total of eight criteria and seven alternatives, as is presented in Table 
1. The dataset presented in Table 1 was retrieved from the database of the National 
Institutional Ranking Framework (NIRF), an initiative by the Ministry of Human 
Resource Development, the Government of India. It has been observed that, for 
different criteria, there are different alternatives that show the best performance. For 
example, the number of vacant seats is the highest in IIT F and the lowest in IIT G. In 
the present scenario, vacant seats in engineering education are the biggest threat in 
India. Therefore, the smaller the number of vacant seats at a college, the more superior 
the college is. The strongest is the faculty in IIT A. The number of the research papers 
published in a Scopus-indexed journal during the last three years, however, is the 
biggest in IIT G. IIT C is also perceived to have the highest sponsored research fund 
compared to the other IITs which are the subject matter of the research study. The 
student success index, i.e. the pass percentage, is the highest in IIT D compared to the 
other newly-introduced IITs. When students’ employment achievements made 
through the placement cell are concerned, however, it is IIT C which shows the best

performance, being far ahead of IIT D.  It was observed that the number of the students 
who had opted for higher studies was maximum in IIT F, whereas the PhD awarded 
were at the maximum value in IIT G. Therefore, no selection of an IIT demonstrating 
the best performance can be made intuitively; such a selection rather requires the 
involvement of the systematic decision-making process, such as the multi-criteria 
decision-making (MCDM) techniques generally used to rank or select one alternative 
or several alternatives from a set of the available options based on multiple and 
usually conflicting attributes. The prior findings show that the application of multi-
objective optimization based on the ratio analysis (MOORA) (Brauers & Zavadskas 
2006), the data envelopment analysis (DEA) (Charnes et al. 1978), SOWIA-MOORA 
(Das et al. 2013), the complex proportional assessment (COPRAS) (Das et al. 2012), 
Preference Ranking Organization METHod for Enrichment of Evaluations 
(PROMETHEE) (Brans & Vincke 1985) etc. algorithms are broadly used in the 
decision-making process.  In this paper, the modified SAW approach (Biswas & Saha 
2019) is used for the ranking of the seven newly-established IITs. The Entropy method 
is used to determine the weight coefficients associated with each criterion. The 
ranking of the performance of the novel method is compared with MOORA and 
COPRAS, and the technique for the order of preference by similarity to ideal solution 
(TOPSIS) (Wang & Elhag 2006) method in order to judge its superiority. A sensitivity 
analysis of the ranking with changing criteria weights is also presented. The best 
ranking obtained is, again, compared with the NIRF ranking, thus showing the efficacy 
of the methodology employed in this paper.  

The paper is organized into several sections, namely as follows: after the 
Introduction and Literature Review sections, Section 2 is a presentation of the 
entropy-based modified SAW methodology with the mathematical formulation of the 
method. In Section 3, the entropy-based modified SAW method for the ranking of IITs 
is applied. The sensitivity analysis for the novel method is presented in Section 4. In 
Section 5, the discussion is presented and the concluding remarks of the paper are 
given. Section 6 is dedicated to the directions for future research. 

2. Methodology 

2.1. Weight Assessment Entropy Method 

 There are a number of weight assessment methods for decision-making 
processes, such as the eigenvector method, the weighted least square method, the 
entropy method, etc. However, the entropy method [Safari et al. (2012)] is more 
suitable for use when the data of the decision matrix are known. The entropy method 
is especially valuable for the examination of disparities between sets of information.  

The formulation of the entropy method is given below: 

Step 1: The formation of the initial decision matrix X=[xij]mxn

where pij is the discrete probability distribution of the ith alternative with respect 
to the jth attribute. The constant k used to ensure that 0 ≤ ej ≤ 1. 

The divergence degree dj can be calculated as follows: 

dj= 1-Ej                          j=1,2,3,……,j      (4) 

Step 3: The final relative weights for the jth attribute can be obtained by means of 
a simple additive normalization:

2.2. Modified SAW Method

where Ai represents the alternatives, i = 1,2, . . . ,m; Fj represents the jth attribute or 
criterion, j = 1, 2,. . . , n, related to the ith alternative; and θij indicates the performance 
rating of each alternative Ai with respect to each criterion Fj. 

The procedures of the modified SAW method are as follows: 

Step 2. The formation of the initial decision matrix X=[xij]mxn.  

Step 3. The normalization of the decision matrix as N=[rij]mxn. 

In this method, several criteria dimensions are first converted into non-
dimensional criteria. For the benefit type criteria, rij,

Here, xij, xi+ and xi- are the elements from the initial decision matrix (X), where 
xi+=max(x1, x2, ....,xm) and  xi- =min(x1, x2, ... , xm). 

Step 4. For the sets of the benefit and non-benefit type criteria, each normalized 
criterion rij is computed on a scale from 0 to 1, where 0 corresponds to the minimum 
and 1 to the maximum assigned value for the corresponding indicator. The amount of 
rij is now classified into five scale values, ranging from 1 to 5, where 5 refers to extreme 
importance, 4 refers to very strong importance, 3 refers to strong importance, 2 refers 
to moderate importance and 1 refers to equal importance. For example, when the 
normalization values of all these criteria are in the interval of (>0.80, 1.00), then the 
scale value (g)=5 is taken. If the normalized value of one of these criteria is in the 
interval of (>0.60, 0.80), then g=4; when the normalized value of all criteria is in the 
interval of (>0.40, 0.60), then g=3; when the normalized value is in the interval (>0.20, 
0.40), then g=2, and when the normalized value is in the interval (>0.00, 0.20), finally 
g finally equals 1. This scaled normalized decision matrix is identified by (Vij). 

Step 5. The elements of the weighted scale value matrix (Qij) are calculated by 
applying the following equation:  

ijiij
vwQ =

where wi is the criteria weight. 

Step5. Compute the overall score (Si) of the alternatives by using the following 

equation:

Ultimately, rank the alternatives based on the descending value of Si.
 

 

3. New IIT Performance Comparison 

In this paper, the entropy-based modified SAW method is used to rank the seven 
newly-developed IITs, namely IIT A, IIT B, IIT C, IIT D, IIT E, IIT F and IIT G, 
respectively. There are three parameters by which the qualities or status of an

engineering college can generally be measured: first, student admission to the college; 
second, the qualification, the research activity and the number of the faculty members; 
and third, the number of students’ examinations and the students who have obtained 
a university degree. A total of eight criteria were judiciously chosen in the paper so as 
to address those parameters adequately. The eight criteria considered for the analysis 
of the performances of the IITs include the following: vacant seats (in %) (VS), the 
strength of the faculty with PhD (FS), the number of the research papers (RP) 
published in a Scopus-indexed journal in the last three years, the sponsored research 
fund (RF) (in lacs), the student success index (SS) or the pass percentage, the number 
of the students who are employed through the placement cell (E), the number of the 
students who opted for higher studies (HS) and the number of the PhD awarded (PA).  
The dataset was retrieved from the published datasheet of the National Institutional 
Ranking Framework (NIRF), 2018, and they are given in Table 1. The meaning and 
importance of the eight different criteria are explained and presented in Table 2, which 
shows us that only the percentage of vacant seats is considered as the non-benefit type 
criterion, or the lower, the better; the seven remaining criteria are considered as the 
benefit type criterion, or the higher, the better. 

After the formation of the decision matrix, as shown in Table 1, the calculations are 
completed and a normalized decision matrix is found, as well as the weighted scale 
normalization decision matrix, and the overall score of the alternatives by the 
following modified SAW algorithm as mentioned in Eqs (7-10) is computed. The final 
rank according to the modified SAW method is presented in Table 7. In order to avoid 
subjective judgments, the entropy method is used to compute the criteria weights. 
Finally, a sensitivity analysis has confirmed the robustness of the ranking results 
achieved through the analysis of the sensitivity of the model. According to the modified 
SAW method, IIT G is found to be in rank 1, which is supported by the ranking of the 
IITs further obtained by using the same dataset (Table 1) by applying other popular 
methods, such as the MOORA, TOPSIS and COPRAS methods, and the results obtained 
are found to corroborate well with those obtained by applying the modified SAW 
method. IIT G is found to be the first in the modified SAW method and the MOORA, 
TOPSIS and COPRAS methods as well.

Table 2: The descriptions of the different criteria for the selection of the best 

IIT 

Criteria Description 
VS VS stands for the number of vacant seats. In India today, the number of 

vacant seats in engineering education is becoming one of the biggest 
threats. Therefore, the minimum vacant seats indicate the superiority of 
one institution over another in terms of the faculty, the infrastructure, 
the curriculum, teaching-learning, research and placement in 
comparison with contemporary institutes, which helps attract students. 
It is a non-benefit type criterion. 

FS FS stands for the strength of the faculty with PhDs. Being the country’s 
premier institutes, IITs always recruit faculty members with an excellent 
academic background and an exceptional research quality in order to 
impart the high quality of education and research. It will result in 
students’ overall improvement and produce quality engineers to cater 
for the needs of the industry and society as a whole. In India, however, 
there is an acute shortage of well-qualified faculties required for 
engineering disciplines at institutes like the IITs, resulting in a tendency 
to decrease the faculty/student ratio. Therefore, the higher the strength 
of the faculty in an IIT, the greater the faculty/student ratio, which is 
desirable in order to achieve continuous improvement in education and 
research. It is a benefit type criterion.   

RP RP stands for the number of the research papers published in Scopus-
indexed journals during the last three years. Citation-based 
measurements are considered to be the quantitative measures of the 
research quality and impact.  The higher its value, the better the quality 
of the research performance in IITs. It is a benefit type criterion. 

RF RF stands for the sponsored research fund (Rs. in Lac). It is important for 
the IITs to be the source of new ideas and innovators in technology and 
science, with the general goal to create an ambience in which new ideas, 
research and scholarship flourish, and from which the leaders and 
innovators of tomorrow emerge. In meeting these points of importance, 
IITs have taken the initiative to promote innovations and carry out 
funded research studies sponsored by different agencies of the 
Government of India and the industry. It is a benefit type criterion. 

SS SS stands for the student success index, or the pass percentage. Academic 
success is important because it directly decides upon students’ positive 
outcomes after graduation.  It lays out a framework for building 
institutions so designed as to promote student success outcomes. 
Students with academic success will have more opportunities to choose 
their future jobs than those less educated. It is a benefit type criterion. 

E E stands for the number of the students who are employed through the 
placement cell. It has been shown that students in IITs with a higher 
CGPA have a smaller probability of remaining unplaced. A survey among 
the graduating batch who had sat for placements strongly hints towards 
CGPA as one of the most important placement factors.  It is the dream of 
every engineering student to find their place in a top-rank organization 



Biswas et al./Oper. Res. Eng. Sci. Theor. Appl. 2 (3) (2019) 65-76 
 

72 
 

which is visiting their campus for the recruitment purpose. Employment 
competition increases every day, and placement has become a 
challenging task. Training students and equipping them with life skills 
has become an important institutional responsibility. Along with 
technical expertise, the development of a holistic personality is also 
necessary. It is a benefit type criterion in this study. 

HS HS stands for the number of the students who opted for higher studies. 
Higher studies assure the significance of their knowledge, identify gaps 
in skills, educate special programmers and build the right skills that can 
help the country to improve, economically prosper and achieve social 
cohesion, adapt the development of the workforce to the economy and 
changing demand for new skills, develop higher standards of 
transparency, strengthen the higher education sector and 
professionalize the sector through stronger institutional responsibilities 
that would help reprioritize the efforts and work around the 
complexities. It is a benefit type criterion in this study. 

PA PA stands for the number of the PhD awarded. A PhD is the doctoral 
degree awarded to the students who defend an original thesis which 
makes a significant new contribution to knowledge in their respective 
fields of interest. PhD qualifications are available in all scientific, 
engineering and management subjects and are normally the highest level 
of the academic degree a person can achieve. It is a benefit type 
criterion.   

3.1 Steps of the Calculation of the Modified SAW Method: 

 (i) The decision matrix for all the IITs is shown in Table 1. Only one IIT (i.e. IIT A) 
is taken into consideration for the calculation. Then, the normalization of the different 
criteria of the alternative IIT A is calculated using Equations 7 and 8. 

 (ii) Finally, the normalization of the different criteria of IIT A is given in Table 3. 
Now, all the normalized values are split into the five scale values, ranging from 1 to 5, 
as is shown in Table 4, where 5 pertains to extreme importance and 1 pertains to equal 
importance. For example, in the case of IIT A, the FS, RF and E criteria normalization 
values are 1, 0.907114 and 0.909091, respectively, which implies the scale value of 5 
in this case, because all the normalization values of the given criteria are in-between 
(0.8-1). In a similar fashion, the other criteria of IIT A, such as VS, RP, SS, HS and PA, 
have the scale values of 2, 4, 4, 3 and 3, respectively. 

(iii) Now, the individual scaled value is multiplied by a particular criterion weight. 
In the case of IIT A, the scale value of the VS criteria is 2, which is now multiplied by wi 
(0.156402) value, the obtained result being 0.312804. In a similar fashion, all the 
weighted scale values of IIT A are found and presented in Table 6. 

(iv) Then, we add all the Qij of IIT A and the obtained Si values of IIT A as follows: 

=0.312804+0.18223+0.171696+1.321135+0.00448+0.12749+0.495192+0.92495
7= 3.539984 

 (v) Correspondingly, (IIT B-IIT G) are calculated applying the same procedure and 
the final ranks are obtained.

4. Sensitivity Analysis 

The results of the MCDM methods significantly depend on the assigned value of the 
relative importance of each criterion, known as weights. Sensitivity analysis is a 
popular means to estimate the effect of a change in weights associated with each 
criterion on the final ranking of alternatives. If changing weights associated with 
certain criteria finally result in a different ranking, the model is considered to be 
sensitive to those weights. Therefore, the stability of an MCDM model is established if 
the final ranking determined by the model remains more or less unaffected by the 
change in weights during the sensitivity analysis. In this section, a sensitivity analysis 
is performed in order to assess how changes in criteria weights affect the ranking of 
the different alternatives of IIT by interchanging the criteria weight values in the order 
of 8C2 i.e. for the eight considered criteria (C1–C8), there are a total of 28 (8C2) possible 
interchanges. Here, 8 is the number of the criteria and 2 is the number of the criteria 
chosen at a time. Therefore, there are maximum 28 possible interchanges in the 
weights during the sensitivity analysis. Figure 1 clearly shows that the interchanges in 
the criteria weights have a very small effect on the rank of the alternatives and the 
ranking of the IITs remains almost unaltered. In almost all the cases, IIT G outperforms 
the other IITs, which indicates the robustness of the ranking of the IITs obtained by 
applying the proposed model. The better performance of IIT G may be due to a very 
small number of vacant seats in comparison with the other IITs which are the subject 
matter of this research study, a much greater number of the published research papers 
and the maximum number of the students awarded a PhD degree in comparison with 
the other IITs. Therefore, the conducted sensitivity analysis allows us to conclude that 
IIT G is the best IIT (in comparison with the other six) in India, which is only followed 
by IIT C, IIT A, IIT B, IIT E, and IIT D, while IIT F ranks the last. 

It has been observed during the analysis that the proposed modified SAW method 
is simple and easy to understand, and, given its lesser mathematical complexity, 
convenient to handle. Furthermore, the robustness of the method is clearly envisaged 
through the sensitivity analysis conducted in this study with the normalized values of 
the different alternatives. In the past, researchers developed different MCDM 
techniques so as to cater for decision-making in different complex real-life problems. 
Those methods, however, are found to be complicated and mathematically complex,

and generally to take too much time to compute, even requiring a linear programming 
tool to solve such models from time to time. The model proposed in this paper has 
been compared with the well-established MCDM techniques, such as TOPSIS, COPRAS 
and MOORA, which is accounted for in Table 7.  A higher degree of the similarity of the 
ranks between the proposed method and the other MCDM techniques is indicative of 
the efficacy of the proposed method. Therefore, given its high degree of accuracy in 
decision-making involving lesser mathematical complexity and little computational 
time, the proposed method will undoubtedly be a very useful tool for decision-makers. 
The entropy method is successfully employed in this paper for the computation of the 
weights. Therefore, the hybrid model consisting of the entropy method and the 
proposed novel method used in this paper have proven to render effective decision-
making for the purpose of evaluating real-life problems, such as the evaluation of the 
performance of the newly-established IITs and so forth. The modified SAW method, 
therefore, can be envisaged as a useful and reliable tool for sensible decision-making.

5. Conclusion 

The overall scores calculated by the application of the method serve to evaluate the 
rank of the alternatives and lead to the selection of a suitable alternative. The modified 
SAW method is logical and provides a good elaboration of the ranking method. The 
suggested methodology can be used for any type of the selection problem with any 
number of attributes. The conducted comparative performance analysis enables us to 
understand that the proposed method outperforms in comparison with the other 
existing and popular MCDM methods. Practitioners may find this research study useful 
in that the same may enable them to use this novel approach to the evaluation of 
performance and the ranking and selection of alternatives in a given set. The

performance demonstrated by the other higher-education institutions, such as NITs 
and Indian universities, is also possible to evaluate by applying the adopted approach. 
Due to the generic nature of the given method, the same can also be applied to solving 
the ranking and selection problem in any sector of society.
