| 摘要: |
| 卫星任务规划与调度是空间资源管理的重要内容之一，其目的在于为卫星系统的任务计划编制提供科学合理的决策手段与依据。卫星任务调度问题的重要特点在于，调度任务存在可见时间窗口约束。只有在可见时间窗口内，调度任务才可能执行并完成。在进行合理假设的基础上，建立卫星任务调度问题的约束规划模型。对基本禁忌搜索算法进行改进，提出了模型求解的变邻域禁忌搜索算法。应用结果表明，约束规划模型的建立与求解是合理的。 |

| Abstract: |
| Mission planning and scheduling of satellite, which is to support task plan making of satellite scientifically, is a main content of space resource management. One of the most important characteristics of satellite mission scheduling is that it is subject to time windows constraint, which means that tasks can only be completed within the given time windows. The scheduling model is formulated based on reasonable assumptions and constraint programming method. The model is solved with Variable Neighborhood Tabu Search (VNTS) algorithm. On the basis of a limited experiment, we observe that the algorithm is very effective in obtaining near-optimal solutions. |
