摘要: 以西北锆管有限责任公司的MIS系统(NWZ–MIS)的开发为背景,详细讨论了一种用于混合流程企业的实用调度算法。该算法的内容主要体现在以下几个方面:合并工艺文件中的相关工序,生成大工序工艺文件,使混合型加工从大工序的观点来看可近似为离散加工;以各工序的动态优先级和加工准备时间为参考完成静态调度;最后,讨论了算法中为增强调度柔性以解决该类企业加工调度中的某些特殊问题而采用的几种处理方法。

Abstract: According to the characteristics of mixed processes, a practical scheduling method is proposed. The method contains three parts. First, a macro process planning is obtained by merging some relevant process steps. On the basis of this macro process planning, mixed processes are regarded as discrete processes. Second, by referring to priority and setup time of process steps, static scheduling is completed. Third, in order to solve some specific issues in the mixed processes and improve the flexibility of the proposed method, some key points are discussed. The method has been used in Northwest Zirconium Co. Ltd. And running results illustrate its effectiveness.

Key words: Macro process planning Priority, Mixed processes Batch processes
