合理下料问题的多目标规划模型

The Goal Programming Mathemntical Model of Cutting Stock Problem Reasonably

本文从现有的四种合理下料问题的单目标线性规划模型中,发现在有关合理下料的问题中并非仅含有一个目标,而是具有双重目标,一个是余料最少;一个是下料最少。这两个目标在一般情况下并非一致的。因此,在此基础上提出了关于合理下料问题的多目标规划模型,并给出了有效解的判定方法及实际中寻求满意解的途径。

The Goal Programming Mathematical Model Ctting Stock Problem Reasonable. The main ontent: this essay deals with the subject that there a re more than one goal in the problem at utting stock reasonably during the research at four singlc goal line programming mathematical odels which are known to us. There are double goals: one is the goal of minimum material left, nother is that at minimum material invested. In most cases, these two goals are not ecessarily onsisteut. For this reanon, we put forward the multigoal programming model about the easanable utting stock problem and come up with the way of judgement of effective answers and The way of inding out the satisfied answer in practice.
