Performance Evaluation Model for Subcontractors in Automotive Rubber Part Supply Chain Management

Performance evaluation is the critical method for supply chain management in any industrial sector in order to maintain competitiveness. Subcontractors are important for producing parts to the Tier 1 companies and OEM under the same standardization and delivering the parts on the purchasing schedule. Therefore, the subcontractors need to improve capability, quality and productivity in the level that is accepted from customers. In automotive rubber part supply chain, it includes OEM, Tier 1 companies and Tier 2 companies in order to share resources, information and technology for the whole cluster. This paper proposes the performance evaluation model using ANFIS system to deal with uncertainty and responsiveness. Three major dimensions are measured based on actual sample factory model. They are delivery on time, back order clearance, and quality. The performance evaluation can be evaluated anytime while demands are being changed in order to optimize supplies of the sub-contractors.
