部件分配问题(CAP)是寻求使系统可靠性最大化的系统中部件位置的最优分配问题。由于相关数据的不充分性和不准确性以及系统的复杂性,在实际工程系统分析中存在着不同类型的不确定性。提出了一种基于扩展Birnbaum重要性(BI)的两阶段启发式算法(EBITS),利用证据网络和区间值BI度量来求解参数和模型不确定条件下的CAPS问题。参数不确定性是关于部件可靠性的不确定性,模型不确定性是关于系统结构的不确定性。将该方法应用于船舶燃油服务系统中阀门的优化配置。
The component assignment problem (CAP) is to find the optimal assignment ofncomponents tonpositions in a system that maximizes the system reliability. Due to the insufficiency and the inaccuracy of related data and system complexities, there are different types of uncertainties in real-world engineering system analysis. This paper proposes an extended Birnbaum importance (BI)-based two-stage (EBITS) heuristic using evidential network and interval-valued BI measures for solving CAPs under parametric and model uncertainties. The parametric uncertainty is the uncertainty about component reliabilities and the model uncertainty is the uncertainty about the system structure. The proposed method is applied to find the optimal assignment of valves in a ship’s fuel service system.
