AI Technical Summary

Technical Problem

Existing technologies cannot balance time cost and high-performance scheduling results in satellite scheduling. Precise algorithms take too long to compute, and heuristic and metaheuristic methods may get stuck in local optima.

Method used

A hierarchical multi-orbit multi-mission satellite scheduling method is adopted. By using mission priority analysis indicators and optimal orbit allocation tool models, combined with a single-orbit mission scheduling function that determines the time dependence of mission value, the large-scale satellite scheduling problem is decomposed into multiple sub-problems for optimization.

Benefits of technology

It provides high-quality mission orbit allocation schemes in a short period of time, improves the optimal accuracy of mission orbit matching results, conforms to the profit changes of actual satellite mission scheduling, and reflects the time dynamics of model scheduling.
