Reliability has been greater concerned in recent years and allocating proper reliability value to each component of a complex system as an optimization process to reduce cost and rise productivity is very important. This paper presents a reliability allocation method based on Bayesian networks (BNs). In this paper, the approach are presented in two main aspects: modelling aspect and analysis aspect...
Fault tree analysis is very important in the reliability design and analysis program of a product. However, the traditional fault tree construction method is difficult to implement since it requires high capability of the modelers and a long period, furthermore the process is complicated. Compared with this, the Go model is easy to build due to its similarity with the principle diagram of the system...
Many problems have existed in synthesis design of reliability, maintainability, supportability (RMS) and performance, such as RMS design activities are numerous and optional, variable feedback branches can satisfy same RMS requirement, some iteration among RMS and Performance activities is necessary, and many uncertainty exist in the design process. A process reengineering method for synthesis design...
During the failure free operating period (FFOP), products have ZERO FAILURE and not unscheduled maintenance. Comparing with the traditional reliability measurement of mean time between failures (MTBF), the concept of FFOP abandons the hypothesis of random failure. Firstly, the essential features of FFOP are expounded; then a powerful equation is derived for setting quantitative reliability requirements...
