ISM方法在航空母舰评估指标体系构建中的应用

Application of ISM on the Construction of Aircraft Carrier Evaluation Index Systems

由于航空母舰系统的复杂性及作战任务的特殊性,需在总体设计阶段进行初步方案论证以保证设计的合理性,而相应评估指标体系的建立是进行方案论证的前提。以ADC效能模型为基础,参考一般水面舰船指标体系并针对航空母舰的特殊性,选取影响航空母舰固有能力的主要指标要素,引入解析结构模型分析法(ISM),将指标要素间的关系转化为矩阵元素,通过矩阵布尔运算建立航空母舰固有能力的结构模型。从评估指标体系的决策应用出发,分析由结构模型转变为评估指标体系的若干要点,建立适用于总体方案决策的航空母舰评估指标体系。通过与既有评估指标体系对比分析发现,在指标要素一定的情况下,根据上述过程建立的评估指标体系具有较好的稳定性和合理性。该方法既可直接用于评估指标体系构建,也可用于对既有指标体系的合理性检验。

Due to the system complexity and the mission particularity of aircraft carriers,a plan demon-stration needs to be conducted during the preliminary design stage in order to ensure design＇s rationality,where the relevant evaluation index system is a precondition for such a demonstration program. Based onthe Availability,Dependability,and Capacity（ADC）model,the key performance indicators for carrier＇scapacity are selected by referencing to the evaluation index system of general surface ships and consideringaircraft carriers＇ particularity. Interpretative Structural Modeling（ISM）is then introduced to convert theseindicators into matrix elements. The structural model of aircraft carriers＇ capacity is also constructedthrough Boolean operation of the matrix. With the decision-making applications in the evaluation index sys？tem,certain elements are analyzed during the conversion between the structural model and the evaluationsystem. Finally,the evaluation system for the overall decision-making of aircraft carrier design is estab？lished. Compared with conventional evaluation index systems,the proposed system demonstrates superiorstability and rationality. The presented method is not only applicable to the construction of evaluation indexsystems,but also to the validation of present index systems.
