An Emergency-Oriented Multi-Airship Cooperative Allocation Method for Earth Observation Tasks

Abstract

The invention discloses an emergency-orientated co-cooperation allocation method for multi-airship earth observation tasks, aiming at dynamically performing task allocation, and increasing the scheduling success rate of the tasks as far as possible. In the technical scheme, the co-cooperation allocation method comprises the steps of: firstly, establishing a task set AT to be allocated, performing positive bid inviting on the tasks in the AT, and screening all resources meeting a basic capacity constraint; secondly, calculating the positive bid values of the resources in a resource competition roulette set according to the capacity of a buffer pool, and biding; choosing the biding resources of the tasks by adopting a Max strategy, determining the positive resources winning the bidding of each task, and performing reverse bid inviting on the task; reversely biding the resources and calculating the reverse biding value for each biding task; and choosing the biding tasks by adopting a roulette strategy, finishing reverse bidding winning to obtain a task allocation result. With the emergency-orientated co-cooperation allocation method disclosed by the invention, on one hand, unnecessary calculation time and unnecessary communication traffic can be reduced; and on other hand, the scheduling success rate of the tasks can be increased.

Description

technical field [0001] The invention relates to a multi-airship cooperative assignment method for earth observation tasks, in particular to a method for carrying out airship task cooperative assignment through an improved contract network mechanism based on multi-Agent two-way bidding under emergency conditions. Background technique [0002] In recent years, airship technology has been continuously matured, and the application of airships to earth observation systems to fill the gap between satellites and unmanned aerial vehicles is becoming a new subject of urgent research by countries all over the world. An airship is a maneuverable space vehicle that relies on buoyancy to lift into the air. Compared with unmanned aerial vehicles, airships have a longer battery life and can be used for fixed-point observation for a long time; compared with satellites, airships are more flexible in control, have lower manufacturing and operating costs, and have no time window restrictions o...

AI Technical Summary

Problems solved by technology

[0009] Airship task allocation is an important part of the airship management and control system. In today's environment where emergency needs are increasing, how to effectively allocate airship tasks to meet the needs of users in emergency situations is a key issue that needs to be solved urgently. At present, there is no multi-Agent-based Public Report on the Method of Collaborative Allocation of Airship Tasks Using the Improved Contract Net Mechanism of Two-Way Bidding
