二水平多目标决策方法的研究

STUDY ON TWO LEVEL MULTIOBJECTIVE DECISION METHOD

本文根据对偶理论建立了二水平多目标线性规划的优化模型,提出了计算方法(DMDO法),并对计及炼油厂效益的公司级排产方案进行优化计算。计算表明:采用二水平多目标模型可得到兼顾炼油厂效益的产品结构。本法计算方便,迭代次数少,有实用意义。

This paper presents a model of two level multiobjective linear programming based on dual theorem and a solving process tested on optimal production planning of company level in which the profits of refineries are considered.It has been shown that the optimal product slate with the profit of refineries taken into account can be obtained by two level multiobjecrive model. The proposed solving process is simple in calculation with less iteration operation and has practical meaning.
