System Reliability Based On Reliability Block Diagram + Simulation Method, Maintenance, Computer Software Development

Calculating the reliability and maintenance indexes of system is an important facet inreliability engineering field. Reliability block diagram(RBD) and simulation experimentation is an effective method to calculate the reliability and maintenance indexes of system. The following work has been done in this paper: Pseudo random number theory and method has been studied by the numbers. A software system based on RBD and simulation experimentation has been developed. Some examples were given to validate the correctness of pseudo random number theory and method. Comparing this software with former version in function. Comparing this software with BlockSim software. Fourteen examples were given. This paper has also done the following work to mend the bugs in the former version: Breaking through the size limit of screen, therefore, it took only one time to form the reliability block diagram(RBD) of a complex system consisting of many components. ;Three kinds of life distributions have been applied: Gamma,Beta,Weibull; Interborough estimate has been done to system MTTF; Optimizing the calculation method of complex system consisting of several sub-systems; Improving calculation speed greatly. A software system based on RBD and simulation experimentation has been developed .It possessed the following functions: calculating the reliability indexes(MTTF,RT) and maintenance indexes(MMT,RMT) of common system(including series,parallel,standby and mixed system) by means of simulating method.Component's life and repair time includes six kinds of distributions :Exponential,Normal,Lognormal, Gamma,Beta and Weibull.
