...‐systems, namely pump and chiller, are supported by stand‐by units with perfect switch‐over devices and the remaining six sub‐systems are prone to failure. Design/methodology/approach Mathematical formulation of the model is carried out using mnemonic rule for these six sub‐systems. Reliability...

...Gamal S. Weheba; Ahmad K. Elshennawy Traditionally, process improvement is considered a defect prevention effort. Current cost models consider the coupled effect of both prevention and appraisal costs on the cost of failure. This paper proposes a new model for the cost of quality, which captures...

The presentation is supported by many empirical data, which show that, in many countries, the phenomenon is going to be close to saturation...

..., the imprecise reliability models of cold standby systems are proposed in the paper. These models suppose that arbitrary probability distributions of the component time to failure are possible and they are restricted only by available information in the form of lower and upper probabilities of some events...
