We propose a new manufacturing system for agile manufacturing. It is necessary for an agile manufacturing system to produce a large amount and many kinds of products with high reliability. We propose a new configuration of manufacturing system, which attains the high flexibility for the high volume production. The system, named High Volume Flexible Manufacturing System (HV -FMS), consists of machining centers arranged in aserial and parallel manner. It is also expected to ensure high productivity for the case of machine troubles. Simulation studies are performed to demonstrate the feasibility and the effectiveness of the proposed system.
We focus on the economical aspect of a high-volume flexible manufacturing system (HV-FMS) for agile manufacturing. We develop a model to estimate the economical behavior of HV-FMS and flexible transfer line. Under several demand patterns which have been generated from historical data, both models are simulated to evaluate the effectiveness ofHV-FMS from an economical view point.
Agility in manufacturing requires a quick response to the changes in quantity of products without losing productivity. A high-volume¯exible manufacturing system (HV-FMS) attains the high¯exibility as well as the high volume production. We consider in this paper the energy-saving effect of HV-FMS from the viewpoint of consumed electric power. We take a production system of cylinder heads for automobile engines as a subject in this study, and draw a comparison of the energy-saving effect between HV-FMS and¯exible transfer line to verify the effectiveness of HV-FMS. Moreover, we discuss the economic effect of high-speed processing at HV-FMS. We measure the energy-saving effect by high-speed processing and give the permissible level for additional tooling cost.
