Research Note: Fuzzy Supplier Selection by Useof Weighted Indices

Since supplier selection is an important part in management fields, thisresearch focuses on weighted non-hierarchical fuzzy model to increase supplychain management performance. Supplier selection researches havesignificantly increased but most of methods have been focused on hierarchicaldetermination of indices. This article by use of a multiple objective functiontried to present a method that can consider non-hierarchical determination ofindices in specific conditions. This research by use of deliverable indices ofsupply chain management tries to select the best suppliers. In this paper it isassumed that all suppliers have the ability to supply needed items but client canonly make a product they provide. Quality of supply chain deliverable, supplychain reliability and supply chain visibility names indices have been selected toincrease efficiency in the supply chain. This approach presents local optimalsolutions by use of a heuristic logic in supply chain management. These indicesare used as fuzzy to select the appropriate suppliers. By this fuzzy method,appropriate supplier can be set for each of the items. The presented approachhave been introduced a weighted indices to determine best supplier in specificconditions. In this research weighted non-hierarchical fuzzy sets have beenused to select appropriate suppliers. This method is useful for supplier selectionproblems
