基于三角模糊数法的外墙保温方案评价研究

Evaluation of Exterior Wall Insulation Scheme Based on Triangular Fuzzy Number Method

在外墙保温配置的决策方案中,需要考虑的许多指标和权重往往是定性的,因此如何较合理的处理这些指标和权重是解决优化配置的关键所在。在外墙保温方案评价中选择五个关键指标,包括全生命周期成本-效益、保温效果、使用寿命、可施工性、防火性等。针对模糊决策问题,提出了一种新的属性权重和属性值均以三角模糊数形式给出的模糊群体决策方法。通过实例计算来表明基于三角模糊数的外墙保温方案优选方法是简单可行的。

In the decision-making exterior wall insulation optimal distribution,many factors need to be involved and these indexes and weights always are qualitative.Therefore how to process these indexes and weights reasonably is the key to solve this kind of questions.Inview of the decision schemes,we choose the five key appraisal indexes,including life-cycle cost,insulation effect,service life,constructionability,fire protection.For the fuzzy multiple attributive group decision making problems,a new method for the fuzzy group multi-attribute decision making that the attribute weights and the attribute values are both in the forms of triangular fuzzy numbers is proposed.The example calculation indicates that decision-making method in this paper is simple and feasible.
