This paper describes Risk Based Inspection (RBI) methodology which is constructed in one of the units of Tehran Oil Refinery, (ISOMAX unit). The result of RBI Execution is a risk matrix which is constructed with Probability of Failure and Consequence of Failure. To define risk, probability of failure and consequence of failure and active damage mechanism were recognized. Riskwise software was a...
Metaheuristic algorithms are preferred by the many researchers to reach the reliability based design optimization (RBDO) of truss structures. The cross-sectional area of the elements of a truss is considered as design variables for the size optimization under frequency constraints. The design of dome truss structures are optimized based on reliability by a popular metaheuristic optimization tec...
Design and operation of complex engineering systems rely on reliability optimization. Such optimization requires us to account for uncertainties expressed in terms complicated, high-dimensional probability distributions, which only samples or data might be available. However, using often degrades the computational efficiency, particularly as conventional failure is estimated indicator function ...
conclusions: absence of the c allele was significantly associated with failure of response. the presence of c allele was associated with a favorable outcome. afp is a strong baseline predictor of hcv treatment response. a decision tree model is useful for predicting the probability of response to therapy. patients and methods: the study included 263 chronic hcv egyptian patients receiving peg-i...
