Problems solved by technology

The pitch lengthens the visible time window between the satellite and the observation target. Therefore, compared with the general satellite scheduling problem, the decision variable is not only the selected task set, but also the specific observation time, which makes the solution of the agile satellite more difficult.

Embodiment Construction

[0106] The purpose of the present invention is to provide a method for constructing an operator of high-efficiency single-satellite scheduling under the condition of ensuring the quality of the solution.

[0107] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention. .

[0108] In one embodiment, as figure 1 As shown, the operator construction framework of single-satellite scheduling consists of problem classifier, algorithm engine and problem operator knowledge base. The algorithm engine is the core component of the recommendation framework, which provides a logical environment for operators to run, and supports the exchange of information about problems, algorithm...

Abstract

The invention discloses an operator construction method of a single-star scheduling. The operator construction method comprises the following steps that a question classifier which is constructed based on a distribution form of a task set conducts classification on single-star scheduling sub-questions; (2) an ant colony algorithm is constructed; (3) a question operator knowledge base is constructed through question classification, an operator design ruler and a score triple and records the historical performance when each operator design is used for solving each type of questions, and therefore operator design decision support is provided for solution of new concrete questions in the feature. The operator construction method of the single-star scheduling has the advantage that under the condition that solution quality is guaranteed, the solving efficiency is high.

Description

technical field [0001] The invention relates to the technical field of aerospace imaging satellite scheduling, in particular to an operator construction method for single-satellite scheduling. Background technique [0002] In recent years, my country's aerospace technology has developed rapidly. Aerospace technology has rapidly expanded from the field of national defense and military to the field of civilian aerospace. The number of satellites owned by my country has increased sharply, and the development and production of satellites have begun to enter the stage of mass production. The satellite scheduling problem is briefly described as follows: given a set of earth observation satellites and ground targets, each ground target has its own observation revenue, the satellite orbit parameters are known, and the visible time period between the satellite and the ground target can be obtained through data preprocessing. Satellite observations of ground targets must be performed ...
