A goal programming approach for supplier evaluation and demand allocation among suppliers
نویسنده
چکیده
This paper presents a hybrid algorithm for supplier evaluation and demand allocation among the suppliers. The objective here is to minimise the inventory and transportation costs and simultaneously to maximise the total purchase value of the items taking into consideration demand condition, supplier capacity, budget and delivery lead-time constraints. Since the problem is multi-objective decision making, we solve this problem by converting all mixed integer programming objectives in to single objective with the help of goal programming approach. The customer demand is allocated among the suppliers by using a hybrid algorithm based on the technique for order preference by similarity to ideal solution (TOPSIS), fuzzy set theory, MILP, and goal programming approaches. The results are validated by computational experiment and prove the efficacy of the hybrid algorithm.

Supplier selection is a multi-criteria problem which includes both tangible and intangible factors in these problems if suppliers have capacity or other different constraints two problems will exist: which suppliers are the best and how much should be purchased from each selected supplier? The objective of this paper is to present an integrated model and a supporting approach for effective ...
متن کاملEvaluation and selection of sustainable suppliers in supply chain using new GP-DEA model with imprecise data
Nowadays, with respect to knowledge growth about enterprise sustainability, sustainable supplier selection is considered a vital factor in sustainable supply chain management. On the other hand, usually in real problems, the data are imprecise. One method that is helpful for the evaluation and selection of the sustainable supplier and has the ability to use a variety of data types is data envel...
