基于模糊层次分析法的工程机械质量评价

工程机械从设计、装配到使用有一个实现过程,每一个环节都包含了多种与机械产品的质量密切相关的评价指标,比较分析这些评价指标,有利于决策者把握重点,提高产品的可靠性和经济性,结合工程机械特点,建立影响机械质量的指标体系,综合运用模糊数学和层次分析结构,建立模糊层次分析模型,提出了隶属度和权重系数的分配方法,通过对某型工程机械的质量评价,对评价方法进行详细介绍,评价结果表明,该方法科学合理,具有较高的实用性和通用性.

Quality evaluation for construction machinery using fuzzy analytic hierarchy process

In an implementation process from design,assembly to usage for construction machinery,the evaluation criteria are contained amongst each process stage.By comparing and analyzing these criteria,it is useful for decision-makers to focus on improving product feasibility and economics.In this respect,a quality-related mechanical evaluation criterion system is established.In details,a fuzzy analytic hierarchy process model,which synthesizes fuzzy theory and analytic hierarchy process,are proposed and investigated via an assignment method for the membership and weighting.Through the quality evaluation for a specific construction machinery,it is found from the evaluation results that this approach possesses its practicality and generality.
