摘　　要：在系统功能和经济费用双约束的条件下,分析N元并联系统可靠性极值度,如何选取元部件使得系统可靠度达到最大值,在什么情况下系统的可靠度会达到最小值,从而构造系统运行过程中的可靠度上下包络线,并对系统功能和经济性能做量化评估。In this paper,the author analyze the extreme reliability on parallel system with N Element obeying exponential distribution,how to select component parts so that the system＇s reliability can reach maximum,and under what circumstances of the reliability of the system will reach the minimum in order to get the up and low reliability envelope curve in running process,thus make a quantitative assessment on function and economic performance.
