采矿工业两级供应链中的协调生产计划建模

Modeling of the Coordinated Production Planning of a Two-Stage Mineral Industry Supply Chain

对由一个矿山和一个选矿厂构成的采矿工业两级供应链中的协调生产计划问题进行了研究,建立了相应的线性规划模型·模型的特点是:①集成采选两个环节的生产计划;②将运输问题集成到生产计划中·模型的目标追求供应链总成本最小·模型适用于由一个矿山和一个选厂所组成的两级供应链或者采选联合企业,且能够较容易地扩展到多个矿山和多个选厂的供应链结构·给出了算例以说明模型的应用·结果表明:能够为矿山和选矿厂的协调生产提供决策支持,能够节省总的生产和运输成本,有潜在的应用价值·

The coordinated production planning of a two-stage mineral industry supply chain is studied, in which one open pit mine and one concentrating mill are involved. A linear programming model is then formulated, which covers two characteristics: ①integrating the production planning of two stages, i.e. the mine and concentrating mill; ②integrating transportation planning and production planning. The model's objective is to minimize the total cost of the supply chain, and it is very applicable but unlimited to the two-stage mineral industry supply chain or the integrated mining-concentrating enterprise with one mine and one mill. It can easily be extended to the supply chain with multiple mines and mills. An application example is given to illustrate the model. The solution shows that the model can offer decision support for the coordinated production of two stages, reduce the total cost of both production and transportation and has a potential of application.
