BEHAVIOUR-BASED CONTROL FOR UNCERTAINTY MANAGEMENT IN MANUFACTURING EXECUTION SYSTEMS

This paper focuses on disturbances handling and uncertainty management in Manufacturing Execution Systems (MES). In real manufacturing environment there are a lot of disturbances such as priority tasks, machine breakdowns, missing materials, absence of labour, quality issues, job lateness, unexpected events, data management and acquisition errors. Behaviour Based Control (BBC) is a type of adaptive control strategy for uncertainty management. In this paper a new structural and functional model for MES uncertainty management will be presented. An attempt will be made to demonstrate the usability of BBC in the field of MES. Some typical modules which have to be used to support the process management on shop floor level are discussed: 1. Process monitoring; 2. Alarm management and automatic corrections; 3. Diagnostics and action selection; 4. Decision support and cockpit task management components. The structural model which describes the component structure and the joints of components in the proposed system is also presented. Keywords
