Reliability Analysis Of Supply Chain Based On Majority Voting System

From the beginning of 1980s, the supply chain has been widespread concerned. Scholars and entrepreneurs from all over the world are exploring and researching a lot theoretically and practically. With the recent rise of global economic integration, there is an increase of uncertainty of customers' requirement and changes in the diversity of the external environment. Especially after the "911", the security and stability of supply chain has become an extremely important issue. Reliability as a very important probability could evaluate effectively on the operational status of the supply chain. Especially when the operating conditions of supply chain change under the external factors, the applicability of probability indicators is extremely important. Thereafter, reliability analysis of Supply Chain has important theoretical and practical significance.The current research on the reliability structural model of supply chain are all for the series-parallel model. My thesis holds that the normal work of a single node in Enterprise Supply Chain cannot guarantee the normal work of the whole supply chain system, so the subsystems in parallel relationship between the internal nodes could not completely meet the supply chain operational model. This thesis analyzes the reliability of supply chain based on the theory of Enterprise Supply Chain Management and Mathematical Reliability. The Equivalent node theory in accordance with productive capacity and classification of production scale is mentioned and for the first time the reliability of enterprise supply chain is researched in Majority Voting System model.We also analyze both the irreparable and reparable supply system and get their reliability function and reliability optimization program.Otherwise, we discuss the relationship between reliability and cost which is about taking the reliability of supply chain as the basic condition, in the circumstances of subsystem as voting system model, how to spend the least cost constructing enterprise supply chain and numerically calculating to support the enterprise supply chain construction and management theoretically.At last, we make a conclusion of the whole thesis and hope for further research work.
