摘要
战时装备维修保障方案制定,需要以保障任务为牵引,逐步将保障任务分解为功能、活动,从而实现对保障过程的建模。以维修保障过程中具有活动约束的任务分解为研究对象,借鉴软件工程中的内聚概念,将基于任务内聚系数的任务分解模型应用到维修保障任务分解。通过对任务、功能内聚系数的公式化计算、定义模型分析的评估准则,为任务分解粒度的控制提供了一种新的分析方法。结合实例计算结果,说明该方法对维修保障过程建模的任务分解粒度确定是有效的。
In wartime, in order to model the equipment maintenance and support process such that maintenance and support plan can be created, the support task should be decomposed to functions and activities. With restrictions in a support process, based on support activities, task decomposition granularity design model is developed in this paper by using the cohesion conception of modularized design in software engineering. By calculating the task and function cohesion metrics, and defining the analysis and evaluation criterion of the model, a new method is proposed for task decomposition granularity design. An example is used to verify the model and method, result shows that it is feasible and effective.
