Supply Chain repairable Model with the Multi-suppliers and Single Demander

This paper studies supply chain repairable system with a number of the same type of independent parts suppliers and the single demander. Suppose that the supply time of the component suppliers has exponential distribution, and the repair/restore time after the supply break has general continuous distribution. Using supplementary variable method, generalized Markov process theory and the Laplace transform technique, the important reliability indices of system are obtained. These indices have significant meaning for evaluating and measuring the supply chain system performance and improving the management level of the supply chain system.
