摘　　要：为使系统可靠性优化配置方法便于在工程中应用和推广,提高运算速度和精度,本文基于工程实际中的两种情形,情形一:总费用限定,求系统最优可靠度;情形二:可靠度限定,求系统最优费用.通过建立数学模型,编制计算机程序,对复杂网络系统进行了优化配置.最后通过实例验证了程序的正确性,为复杂网络系统可靠性优化配置理论在工程实际中应用提供了一定的技术条件.In order to make the method of optimal disposition of system reliability readily applicable to and generalized in the constructional engineering with improved computational speed and accuracy, the optimal disposition of reliability in the complex network system is conducted for two situations in an engineering practice, including development of corresponding mathematic models and computer programs. In case 1: determination of optimal system reliability with a limited overall cost. In case 2: determination of optimal system cost with a limited reliability. The computer programs are justified finally with an engineering practice, providing a definite technical guarantee for the application of the theory of optimal disposition of reliability within a complex network system to the engineering practice.
