Research on Planning Method and Application of In-orbiting Science Experiment Mission of China Space Station

摘要:

为保障中国空间站平台稳定运行,使得在轨设施利用率维持较高水平,建立空间站科学实验任务规划模型,基于冗余原则设计最大时间冗余度下的任务规划方案。考虑设备支持、上下行、功率、工时等复杂约束,优化空间科学应用项目的在轨设施规划,得到制约应用效益最大化的主要因素。以中国空间站建造期生命科学与生物技术方向实验项目为例的算例实验结果表明,规划方案能够实现在轨设施利用率最大化,为在轨资源扩展、上下行能力提升以及地面项目培育等提供参考。

Abstract:

In order to ensure the stable operation of China Space Station and maintain a high utilization rate of the in-orbit facilities, we established a scientific experiment mission planning model of the space station and designed a task planning scheme with maximum time redundancy. Considering complex constraints such as uplink and downlink, power and working hours, we optimized the in-orbit facility planning of the space science application project to obtain the main factors that restrict the maximization of application benefits. Taking the life science and biotechnology experimental project during the construction of China"s space station as an example, the experimental results illustrated that the planning scheme can maximize the utilization rate of in-orbit facilities and effectively improve the application efficiency of the space station. Our study sheds light on expansion of the in-orbit resources, uplink and downlink capacity improvement, and project nurturing on Earth.
