Collaborative Task Allocation of Heterogeneous Multi-Unmanned Platform Based on a Hybrid Improved Contract Net Algorithm

Abstract

On the basis of investigating dynamic collaborative task allocation of heterogeneous multi-unmanned platform, a dynamic collaborative task allocation model was constructed to settle these problems in this paper. Moreover, the contract net algorithm was improved by means of mental coefficients, the blackboard model and the buffer pool mechanism; and a hybrid method of three modified contract net algorithms was applied to dynamic collaborative task allocation of heterogeneous multi-unmanned platform. As a result, not only is the task allocation efficiency raised, but outcomes of collaborative task allocation become more reasonable. As demonstrated by relevant laboratory findings, the corresponding performance is significantly boosted.
