Cost Function Analysis Based on Parameter Sensitivity
Various cost function models have been proposed in the process of studying system reliability allocation,but currently,the applicability of these cost functions is not clear,leading to confusion among researchers and engineering technicians when selecting cost functions.Therefore,this article has organized five three parameter reliability cost models,and conducted feasibility parameter sensitivity analysis,respectively.Subsequently,the characteristics and applicability of various cost functions were discussed.The research results indicate that the curve characteristics of the y3 cost function are more in line with the construction criteria of the cost function and can be used for estimating relative costs.The research results can be provided reference for future scientific research and engineering practice.
