生产调度的稳定性研究

Study of Stability of Production Scheduling

生产调度中存在着大量的约束条件 ,它是否可行完全取决于所有约束条件是否都满足。文章研究了面向约束的调度稳定性问题。给出了硬约束、软约束和约束满意度的定义 ,提出了调度稳定度的概念 。

A production scheduling solution involves a great deal of constrains, which determine the feasibility of the solution. So the study of the stability orientated to constrains is the focus of this paper. The definitions of the satisfaction degree of hard constrains and soft constrains are presented, and a concept of stable degree of production scheduling is proposed. A simulation result demonstrates the significance of the stability degree of scheduling in practical production processes.
