Problems solved by technology

[0004] At present, the commonly used fuzzy comprehensive evaluation method has two limitations: on the one hand, fuzzy sets can only express two states of support and opposition, and cannot express the state of hesitation between support and opposition, and are restricted in expressing and processing uncertain information. On the other hand, the fuzzy comprehensive evaluation method only uses the membership degree information, resulting in a large discrepancy between the evaluation results and the actual situation

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of aerospace scheduling efficiency, and in particular to a method for evaluating the scheduling efficiency of aerospace measurement and control resources based on Pythagorean fuzzy sets. Background technique [0002] Aerospace measurement and control resources are mainly responsible for spacecraft tracking and measurement, telemetry and remote control tasks, ensuring that spacecraft can complete corresponding missions while operating safely and stably. With the rapid growth of the number of spacecraft, the corresponding resource types become more diverse, the resource requirements become more diverse, and the supporting tasks become more complex. This requires a more scientific and efficient scheduling of management and control resources, and how to reasonably judge the effectiveness of current aerospace measurement and control resource scheduling is the premise and basis for scientifi...
