The Holon Type Reconfigurable Shop Floor Management And Control System

With the competitions in global market and the diversification of user requirements,the vendors have to produce a large variety of products in variational batch sizes. Hence,the vendors are increasingly exposed to changes and disturbances. The shop floor is the most important part of a manufactory. Therefore,to develop a universal and adaptive shop floor management and control system that can adapt to changes and disturbances is necessary.There are many factors that can influence the universality and adaptability of the shop floor management and control system. This paper primarily does research on the shop floor's architecture and the implementation technology. We use the holonic theory and component based software development (CBSD) method to introduce the reconfigurability into the system,thereby attaining a universal and adaptive shop floor management and control system.In this paper,the actual status and trend of the research on shop floor management and control system,as well as the functions of Holonic Manufacturing System and Manufacturing Execution System is discussed. In the aspect of architecture,a new holarchy that suit shop floor is presented and virtual shop floor architecture is built according to this holarchy. In the aspect of implementation technology,the functions of the shop floor management and control system is described. The structure of the holonic system management module that achieves the reconfiguration of shop floor organization is discussed in detail. This paper also explains how to use the CBSD method in the course of system development. To show the system's adaptive ability to the changes and disturbances by reconfiguration,an example is given.
