Abstract

An approach to simplify the complexity of controlling a manufacturing system is to break the task into a hierarchy where each level has a narrow responsibility. Among these levels (plant, cell, equipment), the cell is important because it contains hardware and control elements to create a work environment that can run relatively independently of the rest of the factory. In this thesis, an autonomous object-oriented cell control system is designed using object-oriented system to represent the cell hardware knowledge and the cell control knowledge. The cell control system consists of two parts: a core that contains the cell control knowledge, and a shell that allows the core to propagate Itself and to interact with the cell environment. A prototype emulation system is developed on a microcomputer. The prototype system demonstrates the capability of the ICO by running different scenarios. The ICO propagation between cell control computers is also demonstrated by the prototype system.
