摘要
将复杂系统的可靠性数学模型进行简化计算，然后利用复合函数求偏导的方法求解各部件的概率重要度和关键重要度，根据其值来判别系统中的重要部件和关键部件，以便制订最优的改善和控制措施，获得最佳的经济效益．分析表明，这是改善和控制系统，提高系统可靠性的重要分析方法．并对漳村煤矿的高产高效矿井建设进行了系统可靠性最优改善与控制的实例分析．
The mathematical model of reliability of complicated system is simplified,then probability importance and key importance of various parts by partial differentiation method with compound function are evaluated,the important parts and key parts based on calculated values are determined in order to work out the optimal improvement and control measure and obtain optimum economic result.The analysis shows that this is a important method for improving and controlling the system and improving the reliability of the system.The paper analyzes the optimal improvement and control of system reliability for constructing Zhangcun Coal Mine with high capacity and efficiency.
