Research on Supplier Selection Based on Supply Characteristics

Abstract

Aiming at the decision of raw material ordering and transportation of building materials manufacturing enterprises, this paper deeply excavates data and analyzes the construction model. The model is based on five secondary indexes: default rate, undersupply rate, supply deviation degree, relative supply capacity and sufficient supply rate.Finally, the supplier importance evaluation model is constructed based on TOPSIS method, and the suppliers are ranked according to the score. Then, the supplier supply quantity estimation model and the transport operator attrition rate estimation model are established based on the progressive weighted average, and the estimated quantities of supply quantity and attrition rate in the next 24 weeks are given. Considering ordering decision and transportation decision step by step, this paper calculates the number of suppliers needed by enterprises under the guarantee of weekly capacity demand.The supplier evaluation and selection model proposed in this paper can provide better solutions for related enterprises and has practical application value.
