Web-based multi-attribute analysis model for make-or-buy decisions

This paper is concerned with the make-or-buy decision model for manufacturing and procurement problems. We develop a web-based two-step approach such as: 1) the first step, we used the multi-attribute analysis method using AHP(analytic hierarchy process) and 2) second step we used fuzzy set ranking methodologies to integrate the special decision problems that are the problems of multiobjective, multi-criterion, and multi-attributes. We propose a procedure for the comparative judgment and priority for make-or-buy decision and for the optimal resource allocation. First we determine the rank-ordered priority lists of the projects based on the AHP, and then we compute the aggregate fuzzy set rank order. Finally, we develop a systematic and practical program for simple and easy calculation of all the algorithms used in this study. It is found that the proposed model can be validated by comparative computations in various make-or-buy example problems for a cellular manufacturing system.
