Comparative analysis of criteria weight determination in AHP models

Analytic Hierarchy Process or better known as AHP is the method of structuring, measuring, and synthesizing numerous judgments in finding solutions to decision making problems. There are three common methods of determining the criteria weights in AHP; extent analysis, logarithmic least square method (LLSM), and Lambda-Max. This paper identifies the strengths and weaknesses of these three methods based on the weight accuracy and computational level involved in generating the criteria weights using the data of selecting the best catering company by Wang et al [1].
