建筑工程项目实施状态的诊断方法研究(1)——诊断指标的理论分析

Research on the diagnosis method of implementation status in construction engineering projects(1)

对中国近年来建筑工程项目管理现状进行了调查.依据调查的分析结果得知,建筑工程项目中较为普遍的且具有代表性的问题表象共计20类261种,其中决策阶段3类20种、准备阶段5类66种、施工阶段8类143种、结束阶段4类32种.参考和借鉴其他学科的诊断思想,通过rough set中的信息约简和降维变换,提取和确定了这些问题表象的特征及其参数.在此基础上,按照集合理论的映射原理,得出了诊断这些问题的113项指标.依据65位项目管理人员对此113项指标的评价结果,确定了各指标相应的权重,建立了建筑工程项目实施状态的诊断指标体系.研究结果表明,诊断思想的引入对深入分析建筑工程项目管理中存在的问题、提高建筑工程项目管理水平具有重要的理论价值和实用价值.

The actuality of constructions management in China is investigated. It is found that the main problems phenomena could be divided into 20 categories and 261 sub- categories, including 3 categories and 20 sub- categories in decisionmaking stage, 5 categories and 66 sub- categories in arranged stage, 8 categories and 143 sub- categories in construction stage, 4 categories and 32 sub- categories in conclusion stage. With the help of diagnosis thoughts in other science sub- jects, the characteristics and parameters of problems phenomena are refined and determined by means of information reduction of rough set. 113 diagnosis indexes are educed by the mapping principle of set theory. The weights of 113 indexes are determined according to the judgment of 65 project management specialists; and the diagnosis index system of construction project is set up. The result proves that the idea of diagnosis can be used to identify the reasons of management problems in construction projects efficiently.
