Embodiment Construction

[0102] figure 1 It is a schematic diagram of multi-airship earth observation. figure 1 In , the small red square represents the observation target. Different airships have different coverage of the observation area, and there are overlaps in the observation range of some observation targets.

[0103] figure 2 It is an overall flow chart of the present invention, specifically including:

[0104] In the first step, after the task dynamics are achieved, the newly arrived tasks and tasks waiting to be executed are sorted according to the priority, the task set T is constructed, and the set of tasks to be assigned is set A collection of temporary assignment tasks

[0105] The second step is to add the tasks that meet the basic capability constraints into the task set AT to be assigned;

[0106] The third step is to put the tasks that meet the deadline requirements in the task set AT to be assigned into the temporary task set TT;

[0107] Step 4, if the set of temporarily a...

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...
