A Reliability Model of Truck Transportation Using FMEA and FTA

Nowadays the reliability of the logistics in Supply Chain (SC) is realized as an important factor in order to provide high quality of service to customers. The trend of globalization and the development of the communicational technique led to the needs of the high quality of logistics service and the complexity of supply chain. In fact, the better service that customers require, the more important is the reliability of the logistics. Therefore, measuring the reliability of the specific supply chain that differs from industries or products is needed. This paper describes the transportation model. For measuring the transportation reliability, the Fault Tree Analysis (FTA) and Failure Mode and Effect analysis (FMEA) are applied. By identifying the failure events and assessing the evaluation factor, the quantitative reliability of a link is obtained. The classification of the failure is catastrophe and event which could happen in the transportation situation. And each of the failure event is calculated and aggregated based on the severity, occurrence possibility and detection possibility.
