Mold Enterprise Key Equipment To Update The Risk Decision-making Research

Machines renewal is one of many important problems in equipment management. And it becomes the effective approach to enhance the core manufacturing capacity. The mould & die manufacturing is the representative of customer-driven manufacturing. The key machines, as the bottlenecks of the mould & die enterprises, take on irreplaceability and costliness and randomicity of their operation hours. The high decision making risk of the key machines renewal is determined by the two conflicts, which one is betweer tightness of the time limit for mould & die product and the irreplaceability of the key machines and the other is between one-of-a-kind and the costliness of the key machines. So the factors to consider here are much different from those to consider in the mass or batch production. To solve these, after the objective incorporates the lowest total machines running cost and the best degree to satisfy the production and the fewest machines investments, the Entropy Weight Theory and Analytic Hierarchy Process are adopted to calculate the weight of each objective and the Utility Theory is provided to optimize the potential actions, Which is made up of the risk decision-making model of the key machines renewal in the mould & die enterprises. Next, a machine center of a mould & die enterprise is chosen to take as the object of a case study, and the above model is used to make the decision, and the effectiveness and the applicability of the methodology above are illustrated. In the end, based on the business rules of equipment management of a mould & die enterprise, the decision-aiding prototype systems of the machines renewal is developed, which can be served as the decision-making of machines renewal in engineer-to-order with resource-oriented.
