Abstract

The invention provides a task importance evaluation method and system based on task attribute priority mapping, a storage medium and electronic equipment, and relates to the field of satellite task importance evaluation. The method comprises the following steps: constructing a task attribute dynamic fact library, and storing task attribute priority information; performing association mapping on the satellite task and the fact library to obtain an attribute score of the satellite task; obtaining an index weight of the satellite task according to an expert scoring result and a structure entropy weight method; and according to the attribute scores and the index weights of the satellite tasks, obtaining task basic priorities, carrying out hierarchical priority mapping is carried out, and obtaining priority information. The defect that the importance of part of qualitative indexes cannot be directly measured is avoided, the value domain of the value of each qualitative index can be determined, and the difference between the indexes and the information uncertainty are reduced; and layering and non-intersection of task importance evaluation under different task scenes are considered, non-spanning of task evaluation scores among different scenes is realized, and support is provided for a planning stage.

Description

technical field [0001] The invention relates to the technical field of satellite task importance evaluation, in particular to a task importance evaluation method, system, storage medium and electronic equipment based on task attribute priority mapping. Background technique [0002] For the complex and changeable scenarios of moving target planning, various satellite attributes, and complex target behaviors, and the high requirements of satellite task planning for planning accuracy and emergency response capabilities, when users put forward task requirements, resource loads, station network resources, etc. , time window, etc. for quick calculation and screening to generate a planning plan. Therefore, in order to improve the efficiency and accuracy of satellite planning and task arrangement, it is necessary to carry out accurate grading and evaluation of requirements and tasks. [0003] The current evaluation of the satellite field includes four processes: establishment of an...
