卫星的智能规划与调度

以对地观测卫星为例，分析卫星的结构功能和飞行任务的特点，并在此基础上建立卫星智能规划与调度系统。规划与调度系统由卫星模型和推理机组成，其中模型描述卫星结构功能和各种约束条件，推理机分析并解决这些约束条件，形成一个没有冲突的飞行计划。规划与调度系统还具有修正计划的能力，能满足任务删除、更改和新任务插入等需求。

Intelligent planning and scheduling system for spacecraft operations

An intelligent planning and scheduling system for earth observation satellite is developed. The planning and scheduling system is composed of a spacecraft model and a general reasoning engine. The spacecraft model describes spacecraft's structure, resources, function and all kinds of constraints imposed on the spacecraft. The reasoning engine analyzes these constraints and then solves them to get a rational operation plan. The planning and scheduling system can also iteratively repair the existing plan to get a new one by adding tasks, deleting tasks and changing task of the existing plan.
