Model Based on Failure Rate

One of the important issues in the supply chain is the selection of reliable and efficient suppliers, which improves performance and competitive advantage. Therefore, the aim of this research is to implement two evaluation models based on failure rate and NDEA with the approach of choosing the right supplier in 7 separate supply chains of an electrical appliance manufacturing company in Shiraz. In this direction, a series-parallel system was used to evaluate based on the failure rate, which at the first level examines the reliability of the suppliers and at the second level examines the reliability of the devices required for the production of electrical appliances. And in order to calculate the efficiency of suppliers, the NDEA model was also used. The results showed that both presented approaches are suitable for evaluating the performance of the supply chain, because the performance rating of both models has high resolution.
