摘要
Abstract
Satellite data transmission scheduling is to program the missions scientifically using limited resources. Because of the conflict between large task numbers and limited resources and restrictions in terms of satellite visibility,the scheduling for satellite data transmission is very complex.In this paper,a mathematical model of the satellite data transmission scheduling is established,considering the features of the missions,setting a goal to maximize the weighted scheduling success rate. And an improved ant colony optimization algorithm is presented to solve the scheduling problem, which introduces mission⁃straight permutation coding. Based on ant colony system,the algorithm introduces an adaptive probabilistic decision model for biased⁃exploration to adjust ant exploration ratio dynamically. Experimental data demonstrate that the algorithm effectively improves the weighted scheduling success rate of satellite data transmission.关键词
