基于改进广义成本函数的可靠性分配优化

摘要

The key point for reliability allocation optimization is the depiction of the relationship between the reliability index and the factors that impact the allocation.Based on the analysis of internal relationship between reliability cost and kinds of impact factors,the general cost function is improved to integrate the impact factors,and a new optimization model for reliability allocation is constructed for the calculation of reliability index.%可靠性分配优化问题的难点在于影响分配的各类因素与可靠性指标间关系的描述与表达.从可靠性成本与各类影响因素的内在关系人手,通过改进广义成本函数进行各类影响因素的融合处理,构建得出新的可靠性分配优化模型实现可靠性指标的综合求解.
