System Layout

In order to make reconstruction of re-configurable manufacturing system (RCMS) more efficient and fast, a new design method for control structure and system layout is put forward. First, a holon control structure, such as centralized-control, hierarchical control, non-strictly hierarchical control, and distributed control, is introduced. Each function module of the control structure not only has relative independent character and also cooperation with other control structure. It may constitute the required structural according to the market demand at any time to realize re-configurable control goals. At last, the key technology and the implementation method involved in layout design of equipment and system layer are discussed.

This paper analyzes the characteristics of Integrated Fire Control, one of the combat models of the Network-Centric war, and presents the hierarchical control structure of different combat units according to their corresponding functions. The Multi-Agent System structure is also presented, and different Agent models are established according to roles they play in the system. This paper adopts the acquaintance coalition theory and the Contract Net Protocol to realize the negotiation among different hierarchical Agents. The acquaintance coalition has the advantage of reducing the range of bids and costs of communications. The Contract Net Protocol is employed in the three-layer Multi-Agent System, and is an effective negotiation to allocate the missile intercept tasks in real-time and dynamic environment.

We consider the problem of the task-level robot learning from demonstration. In particular, we consider a model that uses the hierarchical control structure. For this model, we propose the problem of selection of action examples. We present a polynomial time algorithm for solution of this problem. Also, we consider some experimental results for task-level learning from demonstration.

To solve the task-process-safety problem of airborne weather radar system, a set of case-inspired safety analysis method is proposed based on the STAMP(Systems-Theoretic Accident Model and Process). Taking weather radar system's task process in approaching stage as an example, a hierarchical control structure is constructed to identify unsafe control actions during the task process, and analyze the potential hazard causes associating with unsafe control actions. Then a safe flight control structure model is constructed and the accident case of Delta Airlines is analyzed to optimize the model. The safety of system task process is improved through putting forward the safe constraints which can control the propagation mechanism of accident. It is indicated through the above analysis that the method can comprehensively identify the potential hazard causes of system, and provide technical support for the safety design of airborne weather radar system.
