摘　　要：系统可靠性理论与方法是近年来系统工程与管理科学领域的一个研究热点,而工程项目管理领域的系统可靠性及其应用研究尚处于开始探索阶段.基于工程项目管理的目标体系,提出了工程项目施工系统可靠性的概念,界定其内涵为工程项目的质量可达性、成本经济性、资源均衡性、工期合理性和施工安全性的总和.根据工程项目施工系统组合性和层次性的特点,构建了施工系统可靠性计算的金字塔模型,运用不交化最小路集法计算工程项目施工系统的可靠性,并给出了系统可靠性计算的符号表达式.最后,工程实例验证了该方法的有效性.为工程项目施工系统可靠性理论与方法研究做了有益的尝试.System reliability theory is becoming a focus of international management science and system engineering research,though specific studies are still at a starting stage in the field of construction project management.According to objective system of engineering project,the connotation of construction system reliability is defined that it is the sum of quality attainability,cost economies,resource equilibrium,working time credibility and construction safety of engineering project.Based on the hierarchy and composability of project construction system,a pyramid model is built.Based on the principle of network reliability,a method of disjointed minimal paths set is proposed and the symbol expression formula is given to calculate construction system reliability.This method proved efficient and accurate by an example and it＇s a useful try on theory and method research of engineering project system reliability.
