Three-stage decision method for production scheduling under uncertainty
不确定条件下生产调度问题的三阶段决策方法

A novel three-stage decision method considering multiple sorts of uncertainties for production scheduling is proposed. Firstly, the decision process for production scheduling under uncertainties is analyzed and divided into three stages, which are basic scheduling, on-line adjusting and recourse. Secondly, the variables are divided into three sorts according to the three stages. Then, two kinds of three-stage mathematical models based on scene-analysis and (approximate) optimal solution are presented, along with the methods for handling variables and solving the problem. These methods for solving problem by stages constitute the basis of the decision making. To illustrate the process of modeling and decision, a chemical batch process is considered as an example.
