Abstract:

The collaborative task assignment of multiairships in emergency is an important and promising problem which is crucial to improve the observing efficiency of airships. In order to solve the issue, an improved contract net mechanism based on the Agent bidirectional auction is proposed. Then the bidirectional auction method and heuristic rule are explained clearly. A multiple objective constraint satisfaction and optimization model is constructed to meet the realtime requirements of emergent observing tasks. Meanwhile, a fast assignment algorithm named dynamical flexible collaborative algorithm (DFCA) is proposed, which aims at the abundantly dynamical tasks. The result of extensive simulation experiments indicates that DFCA can produce a highquality task assignment decision in short time and provide high schedulability as well as priority benefit.
