Investigation on the Software Platform of System Reliability Analysis and Synthetic Evaluation

Reliability analysis and evaluation for large complicated systems is one of the most important investigation directions to promote reliability techniques at all times in recent years. In this paper, a software platform based on Windows 98 (or high version) has been established, using latest reliability analysis theorem, systems estimation techniques and complex language programming method. The platform system consists of six models, which are defined as fault tree analysis, reliability modelling and automatic evaluation, model affirmation, unit evaluation, system synthesis and evaluation, date bank and its manage system. This system has been applied to the manned space flight items of the astronaut system for reliability analysis and system synthesis evaluation. Applications indicate that the software system is credible and practical for using, simple in operation, convenient for maintenance, and can enormously improve the efficiency and precision of evaluation. This platform software can be provided with universal applicability and can be easily popularized to other evaluation systems.
