- Abstract:
- Efficient scheduling algorithm plays a key role in improving the efficacy of tracking and data relay satellite system (TDRS). Scheduling of TDRS aims to scientifically allocate TDRS resources according to the task application information from the users, such that maximal task requirements are met and the optimal activity schedule is made for the TDRS system. The mathematical model is constructed for the TDRS scheduling problem with the consideration of multiple slide windows in real-world requirements. The objective of the model is to maximize the task completion rate and the expectation satisfaction degree of users. The involved constraints include task requirement constraints and resource using constraints. A heuristic algorithm based on time freedom degree is proposed to solve the model, which includes four operators, i.e., evaluation of the time freedom degree of each task, matching between tasks and resources, task insertion and resource update. At last, extensive experimental simulation demonstrates the effectiveness of the proposed algorithm.
