Although the reliability synthesis problem has solved and obtained the application in the project when the system is composed of different distribution units

the conventional model cannot describe system’s overall characteristic.Based on the minimal path sets theory

synthesized the various units’ life random value which is produced by Monte-Carlo method

an analog simulation model is presented.It can effectively extract system’s overall life distribution characteristic.The contrast confirmation proves that the simulation result is ideal.The statistical inference process can realize on the computer

and is convenient for project application.
