总流程优化中的混合整数规划问题

MIXED INTEGER PROGRAMMING IN OVERALL FLOW DIAGRAMS OPTIMIZATION

介绍了在石化工业总流程优化中 ,可以用整数规划来解决的实际问题 ;阐述了在PIMS软件中 ,用EXCEL表格描述这些问题的具体方法 ,以及相应建成的数学模型的表达形式 ;最后给出了在分枝定界法求解中 ,干预PIMS软件求解进程的办法。

Practical problems that can be solved by mixed in teger programming in overall flow diagrams optimization of petrochemical industry are introduced. Concrete methods describing the problems with EXCEL in PMIS software and the relevant mathematical model expression form are expounded as well. In addition, methods intervening the solution process of PMIS software with branch and bonding method are given.
