系统可靠性理论与方法是近年来管理科学与系统工程领域的研究热点,引入施工可靠性指标有助于工程项目管理水平的定量评价.结合可靠性概念和工程项目管理的目标体系,提出了工程项目施工可靠性的内涵,基于模糊数学理论对施工可靠性评价标准进行了研究.通过模糊语气算子之间的运算关系获得各模糊子集的隶属函数,根据最大隶属度原则将可靠性取值空间[0,1]分成七个互不包容的评价区间,有助于对工程项目施工状况做出更科学合理的评价,也为工程项目施工可靠性理论与方法研究做了有益的尝试.
The theory and method of system reliability are the research hotspots in the field of management science and system engineering in recent years. The introduction of construction reliability index is helpful to the quantitative evaluation of engineering project management level. Combined with the concept of reliability and the project management objective system, The construction reliability of the project connotation, based on the theory of fuzzy mathematics to evaluate the reliability of construction standards.From the operation of the fuzzy mood operator to obtain the membership function of each fuzzy subset, according to the principle of the maximum degree of membership reliability value The division of space [0, 1] into seven non-inclusive evaluation intervals helps to make a more scientific and rational evaluation of the construction status of construction projects, and also makes a useful attempt for the study of construction reliability theories and methods.
