| The market competition gets more intense than traditional markets because of the glob-alization of the market economy and the development of electronic information technolo-gy.Enterprises have joined the supply chain system to resist the risks and shocks caused by various uncertain factors.However,in the process of increasingly tight integration of supply chain node companies,the demand for users is greatly diverse,the homogeneity of products and services is serious,the international political situation is complicated,and the trade fric-tion is normalized,which makes the supply chain system increasingly complex.Therefore,it is great theoretical and practical significance to study the reliability analysis of supply chain systems and the optimize system repair strategies.This paper builds a supply chain system model with two buyers,two manufacturers and one retailer as the supply chain system model based on the background of business to cus-tomer model.The paper proposes the model and describes the normal,abnormal and fault states during the operation of the system by considering internal and external risks.Further different assumptions about the supply chain system,analyze the system reliability of the Markov process firstly,and use the example to solve the reliability indexes,analyze the im-pact of changes in failure rate and repair rate on steady-state availability.Then the gen-eralized Markov process is obtained by the supplementary variable method to study the more generalized supply chain system model.Next,the paper draws the state transition prob-ability map,establishes the state transition differential equation,uses the laplace transfor-m,probability analysis and other methods to solve the state of transition probability.Finally,the reliability indexes of the supply chain system model under the B2C business model are solved from the dimension of system state and the node enterprise,and the calculation results are used to solve the intra-system revenue. |
