By using blackboard-based communication paradigm and shared data structure, multiple decision-makers （DMs） can collaboratively solve the tasks-platforms allocation scheduling problems dynamically through the coordinator. This methodo- logy combined with NGA maximizes tasks execution accuracy, also minimizes the weighted total workload of the DM which is measured in terms of intra-DM and inter-DM coordination. The intra-DM employs an optimization-based scheduling algorithm to match the tasks-platforms assignment request with its own platforms. The inter-DM coordinates the exchange of collaborative request information and platforms among DMs using the blackboard architecture. The numerical result shows that the proposed black- board DM framework based on NGA can obtain a near-optimal solution for the tasks-platforms collaborative planning problem. The assignment of platforms-tasks and the patterns of coordination can achieve a nice trade-off between intra-DM and inter-DM coordination workload.展开更多

A hierarchical structure of decision maker in hybrid control systems is presented in this paper, which is that decision maker consists of two components, i.e., policy decision and coordination. Policy decision can design coordination and digital time box. And policy decision consists of two parts, i.e., steady policy decision and transient policy decision. In general,steady policy decision corresponds to steady requirements and transient policy decision corresponds to transient requirements in systems. A chemical concentration control system severs an illustrative example to show the features of the hierarchical decision maker.展开更多
