1_Editor_Words_Vol2_Issue2_p77 IJAHP PREFACE: Mu/Words from the Editor-in-Chief International Journal of the 77 Vol. 2, Issue 2, 2010 Analytic Hierarchy Process ISSN 1936-6744 Words from the Editor-in-Chief Dear IJAHP Readers: This is the second and last IJAHP issue for this year and with this we are proud to announce we are completing our second year of existence. We open this issue with an application by Islam and Ismail showing the use of AHP for the prioritization of long- term objectives in Malaysia to fulfill their vision for 2020, the year in which Malaysia expects to join the group of developed countries. This article is followed by a case study by Khumpaisal et al of how ANP can be used in the management of mega-projects such as Terminal 5 in the London Heathrow International Airport. This article is useful because it provides a framework of analysis that includes social, economic, ecological, technical, and political factors for the management of mega-projects. This article is followed by the Pecchia et al article about the use of an AHP web-based questionnaire to assess fall risks factors among elderly people. The last paper in our peer-reviewed section is written by Stan Lipovetsky and is an interpretation of the AHP eigenvector solution for the lay person. Our essay section also offers an article about the same topic written by the AHP creator, Thomas Saaty. Rozann Saaty, IJAHP managing editor has graciously written an introduction to the two articles. Enjoy this issue!
