提出了基于工作结构分解和层次分析法动态权重的效能评估方法，根据系统工作原理、信号流程和任务要求建立工作任务结构分解模型，根据子任务时间逻辑顺序建立活动结构分解模型。子任务效能采用ADC模型进行评估，子任务权重采用层次分析法计算，并根据子任务的执行时间区间对每个评估时间点的子任务权重进行动态计算，计算得到的效能时间函数曲线能较好地体现系统效能的动态变化过程。最后给出了评估仿真算例。

A method of effectiveness evaluation based on WBS is proposed in this paper. According to the working principle, signal process and task requirement of ship borne TT&C system, the model of work breakdown structure is established, and the activity structure decomposition model is established according to time logical order of subtasks. The evaluation of subtask effectiveness is based on ADC model. The weight of subtask is calculated using AHP method. Different subtask is executed on different time interval, the weight of subtask should be calculated dynamically on every point. The time function curve can describe dynamic change of the effectiveness. Finally，an application example is given, and the results show that the method is reasonable and effective.
