A next generation manufacturing control system for a lean production environment

This thesis focuses on addressing the need for a new approach to the design and implementation of manufacturing control systems for the automotive industry and in particular for high volume engine manufacture. Whilst the operational domain in the automotive industry has moved to lean production techniques, the design of presentday manufacturing control systems is still based on systems intended for use in a mass production environment. The design and implementation of current manufacturing control systems is therefore inappropriate when viewed from a business context. The author proposes that it is possible to create a more appropriate manufacturing control systems based on an optimised use of advanced manufacturing technology within the complete business context. Literature is reviewed to provide a detailed understanding of the relationship between modem operating practices and the application of contemporary control systems. The primary tasks of manufacturing control systems, within the context of a structured systems approach to manufacturing technology, production management and industrial economics are identified. A study of modem manufacturing control system technology is carried out, highlighting the fundamental principles that influence application engineering in this area. The thesis develops a conceptual design framework that aids the identification of attributes required of a next generation manufacturing control system (NGCS), in order to enhance the business performance of lean automotive manufacturing. The architecture for a next generation control system is specified and a Proof of concept system implemented. Potential advances over contemporary practice are identified with the aid of a practical implementation at a major automotive manufacturer.
