一类多级系统的多目标多准则决策

本文以吸收制冷系统的方案优选为例,首先建立了系统的热力学双目标优化模型,用多目标方法求解,生成系统的非劣方案集;然后综合考虑影响系统优劣的更多可定量和不可定量因素以及决策者的偏好等,应用模糊决策方法选出最佳权衡方案。本文的决策思想和方法对于其他类型多级系统的决策具有一定的普遍意义。

Multiobjective-Multicriterion Decision Making for Certain Type Multistage System

As an example, the optimization of an absorption system has been used to establish a biob- jective thermodynamics model by the multiobjective method to generate a noninferior scheme set. More quantitative and qualitative factors and the preference of decision makers be considered comprehensive- ly, the best compromise scheme set is selected by applying fazzy decision method. The decision and method mentioned here are of certain universal significance to the optimiztion of other type multistage system.
