This paper is concerned with the make-or-buy decision model for manufacturing systems. For the purpose of considering the multi-attribute in the decision making, We used two-step approach such as : in the first step, we used the multi-attribute analysis method using AHP(Analytic Hierarchy Process) and in the second step we used fuzzy set ranking methodologies to integrate the special decision problems; those of multi-objective, multi-criterion, and multi-attribute. We have proposed a procedure for the comparative judgement and priority for make-or-buy decision and also for the optimal resource allocation. First the rank-ordered priority lists of the projects are determined based on the AHP, then the aggregate fuzzy set rank order was computed. Finally, we have developed a systematic and practical program for simple and easy calculation of all the algorithms. It is found that the model validated by comparative computations in various make-or-buy example problems in manufacturing system.
