基于ANP的直升机单机森林灭火训练效能评估

现有的直升机单机森林灭火训练效能评估方法仅针对取水灭火过程,忽视了其他任务环节对训练效能的贡献,并假设指标间相互独立,因此导致评估指标体系不全面、指标权重分配不合理,评估结果的可靠性低。利用离散事件系统建模理论建立的事件活动流将直升机单机森林灭火训练任务分解成若干相关活动,活动映射法对各活动效能要素进行分析并转化为效能评估指标,最终构建出全面的两维度效能评估指标体系;网络分析法(ANP)的使用考虑了评估指标间具有的依赖和相关关系,对指标权重进行重新合理分配,评估方法更符合问题的实际情况,评估结果更加可信。基于超级决策(SD)软件的案例分析表明,所提出的效能评估方法具有工程应用的可行性和参考价值。

Effectiveness evaluation for single helicopter forest firefighting training based on ANP

Existing effectiveness evaluation methods for single helicopter forest firefighting training only aim at process of firefighting and getting water,ignore contributions of other processes during task to the training effectiveness,and assume mutual independence of indexes,which leads to incomplete evaluation index system,unreasonable distribution of indexes' weights and low reliability of evaluating results.The event-activity flow established by using theory of discrete event system modeling divides the task of single helicopter forest firefighting training into several related activities;the method mapping from activities analyzes elements of activities' effectiveness,transforms them into effectiveness evaluation indexes,and finally establishes all-sided two-dimensional effectiveness evaluation index system;with the dependency and relationship between evaluation indexes considered,the use of analytic network process (ANP) reallocates the weights of indexes reasonably,making evaluation method more suitable for actual situation of the problem and results of evaluation more reliable.The analysis of a case based on Super Decisions (SD) indicates that the proposed effectiveness evaluation method possesses feasibility and reference value in engineering applications.
