A contract network mechanism-based dynamic planning method for earth observation resources

Abstract

The invention belongs to the field of satellite remote sensing, and discloses a contract network mechanism-based earth observation resource dynamic planning method, which adopts a distributed collaborative planning architecture from bottom to top and a collaborative planning process based on a contract network; and carrying out dynamic allocation on the large-scale concurrent tasks through a multi-round incomplete combination allocation method. On the basis of analyzing an existing planning system and a resource operation mode, the method starts from an underlying architecture; A bottom-up distributed contract network collaborative planning framework is provided and a planning process is given by breaking through the thinking theorem of a top-down inherent planning mode and combining the distributed computing advantages of the contract network to the dynamic planning problem of air-space-ground heterogeneous resources, so that the computing advantages of the distributed resources are brought into full play, and the task allocation efficiency is improved. On the basis, a large-scale task-oriented multi-class incomplete combination distribution method is provided by adopting three strategies of combination task segmentation, multi-task set synchronous distribution and multi-level matching, so that a large number of concurrent tasks can be quickly distributed.

Description

technical field

[0001] The invention relates to a method for dynamic programming of earth observation resources based on a contract network mechanism. Background technique

[0002] Air-space-ground integrated earth observation, including observation resources such as satellites, drones, and ground sensors, plays a key role in many aspects such as environmental monitoring, disaster assessment, urban analysis, and national security. Different application fields have different requirements for observation resources in terms of spatial resolution, time window, and spectral band. With the improvement of industrial production and observation means, earth observation is becoming more and more refined, in order to meet the different needs of earth observation in various fields. However, due to the limitations of its inherent observation methods and observation capabilities, a single resource cannot meet the needs of many heterogeneous observations. Therefore, the collaborative plan...
