Reliability analysis considering multiple possible states is known as multi-state (MS) reliability analysis. Multi-state system reliability models allow both the system and its components to assume more than two levels of performance. Through multi-state reliability models provide more realistic and more precise representations of engineering systems, they are much more complex and present major difficulties...
Product's life cycle is a continuous and variational time process and can be divided into a sequence of life phase. In this paper, product development process was viewed as an optimization process to find a process set under given evaluation factors such that the set of evaluation indices of entire life cycle is optimized. Based on this, the digital model of integrated product and process development...
The crankshaft is an important component of diesel engine. In this paper, a three-dimensional model of a diesel engine crankshaft was established corresponding to the practical conditions by Using PRO/E software. Using ANSYS analysis tool, the finite element analysis for the crankshaft was conducted under extreme operation conditions, and the stress distribution of the crankshaft was presented. The...
In this paper, a fuzzy reliability allocation method of product is developed based on the experts' knowledge, where fuzzy set theory and analytic hierarchy process are used to decrease the influence of decision-makers' subjective preferences and the fuzzy and uncertain factors during the decision process. In the reliability allocation process, when selecting the influence factors and determining their...
