Designing a Model to Determine the Reliability and Ranking of Suppliers of Electronic Components Based on the Failure Rate

Choosing the right suppliers is the basis of a successful supply chain and a key factor for improving competitiveness. Therefore, the purpose of the present study is to investigate the quality and failure rate of the parts that provided by the suppliers. In doing so,  the evaluation approach based on the failure rate was used and the reliability of the suppliers was determined and their ranking was done. As a result, the research method used is applied in nature and its method is contextual-case. Moreover, for the purpose of a case study, the suppliers of seven separate supply chains of an electrical appliance manufacturing company in Shiraz were examined that each of the chains included eight suppliers. Besides, in order to evaluate and establish the supplier's reliability model based on the failure rate, a parallel system was used. Finally, by calculating the reliability, the failure rate of the supplier's manufactured product was obtained. The results showed that this failure rate is a suitable criterion for comparing the output quality or the products of suppliers. Thus, it is possible to rate the suppliers based on this obtained model.
