确定混煤配比方案的灰色优化方法

对于多方案、多状态、多目标的工程问题，可以应用灰色系统理论建立一个以各目标为坐标轴的欧氏空间（ 效果空间） ，并在此空间内定义一个灰靶，将由状态和方案组成的局势，在目标上的观测值向效果空间进行映射，以求得最优方案。本文以电厂混煤燃烧问题为例，在３ 种目标下，对３ 种混煤方案进行了优化选择。

GRAY OPTIMIZED METHOD FOR DETERMINING THE RATIO SOLUTION OF MIXED COAL

For the multi solution and multi goal engineering problem,gray system theory can be used to establish a Europian space(effect space),oriented at each goal.A gray target can be defined in this space.The observation value of the structure on the target can be cast upon the effect space to get the optimized xolution.This structure is made up of status and solutions.In this article the burning of mixed coal in a power plant is taken as an example.Under the circumstance of three goals,optimized choice is made among three mixed coal solutions.
