This paper described the present risks existing in subway construction and proposed the idea that reliability theory can be applied in the field of subway construction. Based on this, a parallel-series model of risk control system was established. According to the required target of system reliability, combining with the reliability distribution theory, the reliabilities of each subsystem that constituted the parallel-series model can be determined. Aiming at the basic events that constituted the subsystem, average allocation method was taken to solve the basic events reliabilities and an example was given. This studies showed that reliability theory can be successfully applied in the field of subway construction and can fulfill the optimization of construction safety under a given security target.

This work deals with the hesitant fuzzy number and averaging operator and fuzzy reliability with the help of Weibull lifetime distribution. Fuzzy reliability function and triangular hesitant fuzzy number also computed with α-cut set of the proposed reliability function. After applying the averaging operator of hesitant theory, the results are better than simple fuzzy. Also at last, a numerical example has been shown that how the hesitant fuzzy and α-cut work in case of reliability theory.

Objective System

System reliability theory is becoming a focus of international management science and system engineering research, though specific studies are still at a starting stage in the field of engineering project management. According to objective system of engineering project, the connotation of construction reliability is defined and based on principle of network reliability, a method of disjointed minimal paths set is proposed and the symbol expression formula is given to calculate construction reliability. This method is proved efficient and accurate by an example and useful try on theory and method research of engineering project system reliability is made.

Permutation Equivalent

More applications of the principle for interchanging components due to Boland et al. (1989) in reliability theory are presented. In the context of active redundancy improvement we show that if two nodes are permutation equivalent then allocating a redundancy component to the weaker position always results in a larger increase in system reliability, which generalizes a previous result due to Boland et al. (1992). In the case of standby redundancy enhancement, we prove that a series (parallel) system is the only system for which standby redundancy at the component level is always more (less) effective than at the system level. Finally, the principle for interchanging components is extended from binary systems to the more complicated multistate systems.
