- Abstract:

With the ongoing development of aerospace science and technology, satellite clusters consisting of many kinds of heterogeneous satellites have gradually appeared. Compared with traditional satellite systems, satellite clusters have some particular characteristics, including large-scale heterogeneous satellite platforms and various loads. It is difficult to use traditional methods to program satellite tasks. To address the problem of the formation of an agent team for task-oriented satellites, which is one of the key problems of satellite cluster task scheduling, in this study, we built a mathematical model, designed a precise searching algorithm based on branch and bound techniques, and analyzed the associated time complexity. To overcome the high time complexity that characterizes this precise algorithm, we introduced a heuristic pruning mechanism and designed three heuristic algorithms for the formation of the satellite team according to different task sequencing strategies. Finally, we conducted a series of experiments to analyze the performances of the precise search algorithm developed for the satellite team and the heuristic pruning search algorithm and demonstrated the effectiveness and practicability of both the proposed algorithms.
