Application Of Fuzzy Analytical Hierarchy Process and Fuzzy Multiobjective Linear Programming For Selection and Evaluation Of Suppliers

S. Komsiyah

Abstract



Many alternative of problems in management and administration are known as multi attribute decision problems. Such problems involve decisions that must take into account large numbers of variables and objectives that cannot always be easily determined. One very popular approach to handling this class of problem is called analytical hierarchy process (AHP). AHP affords a technique for structuring this class of problems so that it can be given a quasi-quantitative structure. This permits handling any number of variables and objectives. The problem of the multi-attribute type is such as the selection of alternative of software, car, research propose, university, the best employee, and etc. In This paper developed a hybrid approach using Fuzzy- analytical hierarchy process (F-AHP) and Fuzzy-multi objective linear programming (F-MOLP) to the selection and evaluation of suppliers. The case study take five criteria such as trust, price, transportation cost, quality of rejection, percentage of late delivered item (lead time), and after sales services as criteria for supplier selection. From the result of FAHP method obtained weights vector is W = (0, 0.333, 0 , 0.333, 0, 0.333) each respectively to weight vector of trust criteria, price, transportation cost, quality of rejection, lead time, and after sales services. And then the supplier ranking for four suppliers evaluated using fuzzy multiobjective linear programming.
