The invention relates to a satellite task support efficiency evaluation method, which comprises the following steps of: 1, performing multi-dimensional decomposition on a satellite task according to basic information of a satellite; 2, performing digital representation on complex expert experience by using an evaluation experience knowledge extraction method based on a Bayesian network; and 3, performing probabilistic reasoning on the Bayesian network established in the above step by using satellite health state telemetry data which is reasonably quantified and normalized, and finally obtaining an efficiency evaluation result of each dimension of a satellite task. According to the method, the Bayesian network is used as a data extraction and decision inference mode, and digital representation of complex expert experience and decision evaluation of a task scene are achieved. 本发明涉及一种卫星任务支持效能评估方法，包括以下步骤：步骤一、依据卫星的基础信息，将卫星任务进行多维度分解；步骤二、利用基于贝叶斯网络的评估经验知识提取方法，对复杂的专家经验进行数字化表征；步骤三、利用合理量化并归一化处理的卫星健康状态遥测数据，对上述步骤中建立的贝叶斯网络
