Reliability study on a sprinkler system based on the new proposal for old high-rise buildings in Hong Kong was carried out. Fault tree analysis was used to analyze the reliability of the sprinkler system. The mean fractional dead time representing the failure probability of the sprinkler system on demand was calculated. It is found that the design is not so promising because of using smaller ta...

Accompanying the unprecedented outburst of Free Trade Agreements (FTAs), scholarly interests in the new wave of regionalism have been flourishing. Yet, notwithstanding its contribution, extant literature has paid little attention to an important aspect of FTA formation: the choice of FTA partners and the underlying structure of the FTA network. While theoretical conjectures about likely FTA par...

Dynamic Fault Trees (DFT) are a generalization of Fault Trees which allows the evaluation of the reliability of complex and redundant systems. We propose to analyze DFT by a new version of time parallel simulation method we have recently introduced. This method takes into account the monotonicity of the sample-paths to derive upper and lower bounds of the paths which become tighter when we incr...

The performances of almost all available fault tree analysis tools are limited by the performance of the prime implicant computation procedure they use. All these procedures manipulate the prime implicants of the fault trees explicitly, so that their complexities are directly related to the number of prime implicants to be generated. This paper presents a new analysis method of coherent as well...

in recent years, many manufacturing industries for promoting their efficiency have tended to use the automatic manufacturing systems. expanding automatic systems and to increase their complexity are representing the necessity of studying a proper functional quality and using reliable equipment in such systems more than ever. in this direction, the technique of fault tree analysis (fta), along w...

Introduction: Chemical industries often have risks for the environment and communities, due to the use of complex facilities and processes. Also, in the ammonia tanks, the probability of risk of explosion is high, owing to their specific characteristics. The aim of this study is to evaluate the risks of explosion scenario at the ammonia tank in the Kermanshah petrochemical complex Material and...
