基于可能－满意度的施工临时设施优选模型

在施工系统中, 重大临时设施厂址选择常常涉及到大量的不确定性因素。本文用可能-满意度指标测度在厂址选择过程中因素的不确定性, 模糊性和决策者的主观性, 并提出可能-满意度的确定方法。采用系统层次分析方法, 建立了厂址优选模型。通过实例分析说明这种决策方法是比较客观、合理的。

A Model of sythetic Evaluation for Location Choice Based on Possibility -Satisfiability

There are a lot of uncertainty factors which affect the location choice of the important temporary facilities in construction system. This paper introduces the possibility-satisfiability index which can measure uncertainty and ruzziness of the factors, and the dexision-maker's subjcetivity in the evaluation of the location choice. It gives the computational methods of possibility-satisfiability in- dex of the factors. A model of synthetic evaluation for location chioce is estabished by means of the analytic hierarchy process, and applied in a power station. The results show thta this decision method is reasonable.
