Abstract: Space-Based Information System(SBIS) task requirements are complex and inconstant,SBIS task-flow measurement method based on SBIS task-flow model is researched.Two methods respectively based on factors analysis and queuing theory are proposed,which lay the foundation for using task-flow model in solving practical problems.Then the task-flow model is applied in analyzing emergency operations preparation,problem solving models are established for action timing and rapid launch of small satellites,experiments has been done to verify the validity of task-flow method.

摘要: 天基信息系统任务需求具有复杂、多变的特点,在建立天基信息系统任务流模型的基础上,研究了天基信息系统任务流的度量方法,分别基于因素分析与排队论提出了两种不同的度量函数,为应用任务流模型量化分析实际问题奠定了基础。研究了任务流模型在应急作战准备中的应用,针对作战时机选择、快速发射小卫星两个问题,提出了基于任务流模型的分析方法,给出了相应的问题求解模型,通过实验验证了方法的有效性。
