摘要
论文从人的因素、物的因素、信息因素、经济因素、环境因素等五个方面选取了21个评价指标,构建了勘察设计阶段工程质量的指标体系。基于可拓学原理,建立了评价物元模型,并在模型中引入变异系数法确定权重,从而增强了权重的客观性,最后通过关联函数,可以更加精确的确定待评价的项目关于各个评价等级的关联度,从而使工程勘察设计阶段质量等级的评价更加准确全面。
This paper selected 21 evaluation indexes from five aspects, such as human factors, material factors, information factors,economic factors and environmental factors, constructed the index system of survey and design stage of the project quality. Based on the theory of extenics, the matter-element evaluation model was established, and the variation coefficient method was introduced to determine the weight in this model, so as to enhance the objectivity of the weight. Finally through the correlation functions, it can be more accurate for evaluation of the project to determine the correlation of each evaluation grade so that the engineering survey and design stage of quality grade evaluation more accurate.
