A Scheduling Model of Coal Supply Chain Based on Supply Chain Management (SCM)

In this paper, we develop a scheduling model based on SCM to deal with the contradiction between scale production and customized demand on coal industry. When analyzing the coal logistics from coal mine to end-customers, we draw an operating flow chart, from which we can find out the relationship among the departments in coal supply chain. According to the flow chart we can describe the input/output (I/O) constraints by algebraic expression. The objective function minimizes the operating costs of every department in coal supply chain, and an optimal solution can be obtained through the use of Mixed-integer linear programming (MILP). In that way we can get a specific task timetable to guild their work and the activities.
