To control the subdivision of task decomposition, a new method based on cohesion and granularity was proposed to evaluate the task decomposition for operations. First, the task association matrix was obtained based on input and output relationship between tasks. Then, the associated coefficient and reuse coefficient that have effect on task set were analyzed, a cohesion quantized model was established based on task associated matrix. Taking the task quantity and cohesion into account, the task granularity was selected as an important criterion to evaluate task decomposition, and a task granularity planning method was proposed. Finally, an example was given to show the effectiveness and feasibility of this method. The strategy can evaluate task decomposition scheme from task structure, quantity and cohesion.%针对任务分解细化程度难以把握的问题,提出基于内聚度和粒度的作战任务分解评估策略.首先,根据作战任务之间的输入输出关系,映射得到任务关联矩阵.其次,分析影响任务集内聚度的关联系数和任务重用系数,建立基于任务关联矩阵的内聚度量化模型.综合考虑任务数量和内聚度等因素,将任务粒度作为评估任务分解的重要依据,给出了定性与定量分析相结合的任务粒度规划方法.最后通过实例说明了该策略的有效性和可行性.本策略可以从任务结构、数量、内聚度等方面判定任务分解方案的优劣程度,为任务分解提供了一种可比较的评估方法,有利于提高任务分解的可控性.
