QFD与D-S结合的维修性设计评估方法研究

Research on evaluation method of maintainability design based on QFD and D-S theory

分析了维修性设计评估方法的不足,提出了基于需求分析的质量功能配置(quality function deployment,QFD)与证据理论(D-S theory)相结合的评估方法.该方法能够紧密反映军方需求,综合利用了QFD对需求分析和D-S对不确定性处理的优势.以图表的形式反映整个评估过程,具有一定的工程实用特性.

After analyzing the disadvantages of the existing evaluation methods of maintainability design, an evaluation method integrating quality function deployment（QFD） and D-S based on requirement analysis was proposed. The method combined the advantages of QFD and D-S in dealing with uncertainty and could closely reflect the military demand. The total process was represented by diagrams, which had some engineering practicability.
