| Abstract: | Based on belief reliability theory, this paper proposes a reliability evaluation model for complex equipment supply chain considering its development characteristics and uncertainties. The reliability evaluation indexes of member enterprises are established from three dimensions of quality reliability, delivery reliability and development cost reliability. Then the reliability evaluation model of general parts suppliers and newly developed parts suppliers are built based on probability measuring and uncertainty measuring respectively. On the supply chain system level, the reliability interaction between newly developed parts suppliers that results from shared knowledge and information is eliminated by calculating cumulative reliability. The reliability evaluation model of complex equipment supply chain is presented with system structure function. Considering supply chain cost, two mathematical programming models are established to maximize supply chain reliability and minimize additional cost budget respectively. The optimal capacity improvement and budget supplement strategies of supply chain members are obtained. A simplified aircraft development supply chain is analyzed to verify the feasibility and effectiveness of the model. The results show that supply chain reliability can be guaranteed even if alternative suppliers with low reliability are selected, and the increasement of supply chain reliability is diminishing with the increase of additional cost budgeting. This paper will provide a theoretical support for evaluating the reliability of complex equipment supply chain, identifying system weak links and implementing reliability optimization. |
