摘要
针对航班地面保障过程决策能力不足、运行效率低下的问题,提出一种基于国防部体系结构框架(department of defense architecture framework,DoDAF)的航班地面保障过程决策支持模型。从保障作业、保障资源以及二者间关联关系出发,定量描述航班地面保障过程,将DoDAF与基于模型的系统工程(model-based systems engineering,MBSE)相结合建立航班地面保障过程决策支持模型,建立决策效用函数,分析航班保障各环节综合保障的效用值。对比实际数据与本文决策支持模型得到的数据,结果表明决策后的撤轮挡时间与目标撤轮档时间的平均绝对误差对比实际撤轮档时间和目标撤轮档时间的平均绝对误差降低1.42 min,均方根误差降低0.95 min,对于不同机型航班,决策后的保障服务时间与计划保障时间相对误差对比决策前分别降低31%、17%和42%,同时可以得到保障时间与保障效用的关系,证明本文提出的决策模型的可行性和有效性。
Aiming at the problems of insufficient decision-making ability and low operational efficiency of the flight ground support process,a decision support model of the flight ground support process based on the department of defense architecture framework(DoDAF)is proposed.Starting from the support operation,support resources,and the relationship between them,the quantitative description of the flight ground support process is performed.DoDAF and the model-based systems engineering(MBSE)modeling method are combined to establish a decision support model of the flight ground support process.The decision utility function is established to analyze the utility value of the comprehensive support of each link of flight support.The actual data are compared with the data obtained from the decision support model.The results show that the mean absolute error and the root mean square error between the off-block time after the decision and the target off-block time are reduced by 1.42 min and 0.95 min,respectively,compared to those between the actual off-block time and the target off-block time.For flights of different aircraft types,the relative errors between the support service time and the planned support service time after the decision are reduced by 31%,17%,and 42%compared with those before the decision,and the relationship between support time and support utility can be obtained,which proves the feasibility and effectiveness of the proposed decision model.
