Abstract

The invention provides a pointer neural network-based single-satellite emergency task planning method and system, belonging to the technical field of satellite dispatching. The method includes forming multiple pieces of training data from the task requirement data set; generating an emergency task planning scheme; judging whether the number of iterations is greater than or equal to the number threshold; in the case of judging that the number of iterations is less than the number threshold, calculating the benefit; judging whether the number of iterations is equal to the initial value; when it is judged that the number of iterations is equal to the initial value, update the parameters according to the income; when it is judged that the number of iterations is not equal to the initial value, update the parameters according to the smoothed income; update the number of iterations; when it is judged that the number of iterations is greater than or equal to the number threshold, test The pointer neural network is used to judge whether the accuracy requirements are met; when the accuracy requirements are not met, the number of iterations is reset to the initial value; when the pointer neural network is judged to meet the accuracy requirements, the actual task requirements are received; the pointer neural network is used to generate emergency Mission planning scheme.

Description

technical field [0001] The invention relates to the technical field of satellite scheduling, in particular to a single-satellite emergency task planning method and system based on a pointer neural network. Background technique [0002] Imaging satellites are an important means of obtaining ground image information, and have important strategic value and wide application requirements. The satellite emergency mission planning technology is located at the center of the imaging satellite mission management and control platform. It is mainly responsible for solving resource contention and mission conflicts, optimizing the use efficiency of satellites, and facing the current situation of limited satellite resources, numerous imaging requirements, and strong response timeliness. important. [0003] The satellite emergency mission planning problem is a kind of combinatorial optimization problem with high complexity and high timeliness. Although the traditional exact solution algor...
