Optimization of planning and scheduling for phosphor-chemical enterprises

The decision of planning and scheduling for phosphor-chemical enterprise is very complex and difficult, which is a research area that needs to be studied thoroughly. In this paper, a model optimizing planning and scheduling for a phosphor-chemical enterprise is presented in consideration of the operation processes, including mining, mineral processing and chemical fertilizer producing. Also, some numerical examples for the model are computed and analyzed for the purpose of illustration. The results show that it is very useful for an enterprise to optimize production planning and scheduling
