摘要: 再次出动准备时间TAT(Turnaround Time)是衡量军用飞机作战能力的主要参数,针对如何分析计算军用飞机再次出动准备时间这一问题,从军用飞机任务类型、设计特性和使用保障资源三个方面详细分析飞机再次出动准备时间的影响因素,给出了单架飞机再次出动准备时间计算方法.在计算TAT时,综合了飞机的任务类型比,构建了任务类型矩阵和再次出动准备时间矩阵.用矩阵描述再次出动准备时间工作项目之间的逻辑关系,对矩阵节点进行等级划分和拓扑排序.通过计算结果确定关键工作项目,找出影响再次出动准备时间的关键因素,为装备设计改进和使用保障资源规划提供辅助决策.Abstract: The turnaround time (TAT) is one of main measurement parameter for evaluating the fight capability of military airplane. In order to solve the problem of how to analysis and compute military airplane-s TAT, based on the discussion of impact factors on TAT from military airplane-s mission type, design characteristics and operational support resource, a calculation method for one military aircraft-s TAT was provided. While computing the TAT, the airplane-s mission type percentage was integrated and mission type matrix and TAT matrix was constructed. A matrix was used to define the logic relationship between work items of turnaround activity. The elements of this matrix were ranked and ordered topologically, and the results were put in sets for computing. Based on the results critical work items of each mission type TAT were determined, and the critical impacting factors on this mission type TAT were obtained. These factors will provide auxiliary decision for improving military airplane design and operational support resources planning.
