Development of High Speed and High Volume FMS for Agile Manufacturing

敏捷制造作为一种新的下一代制造理念，能够快速响应客户快速变化和个性化的需求，引起了人们的广泛关注。在这项研究中，大批量制造系统的汽车行业的研究重点是能力，以取代和/或补充大规模生产系统，以实现敏捷制造。研究了该系统的体系结构及其运行系统，以阐明该系统的特点及其与敏捷制造的一致性。该系统的经济方面也进行了比较，与传统的柔性传输线，证明其有效性。主要研究结果如下：1.研究了大批量生产中柔性制造系统对品种和批量变化的敏捷性，提出了一种高速大批量柔性制造系统（HV-FMS）.提出了一种并行和串行的机床布局作为所提出的FMS的系统配置，并开发了一个仿真系统进行性能评估.对HV-FMS和FTL开发模型进行了经济性研究，以评价其经济性。研究表明，在不同的需求情况下，HV-FMS比FTL更经济。提出了一种新的基于拍卖方法的控制方法，用于工件、机器和AGV之间的选择和分配，作为HV-FMS的自主操作系统，并研究了其有效性，为HV-FMS的进一步开发提供了依据。

Agile manufacturing has attracted a considerable attention as a new manufacturing concept for next generation which quickly responds to a rapidly varying and personalizing demands of customers. In this study, a high volume manufacturing system for automotive industries is investigated focusing on the capability to replace and/or to supplement the mass production system in order to materialize the agile manufacturing. The system configuration of the proposed system together with its operational system was studied to clarify the characteristics and the conformity of the system to agile manufacturing. Economical aspect of the system was also compared with a conventional flexible transfer line, demonstrating its effectiveness. The major results obtained are summarized as follows :1. A high speed and high volume FMS(HV-FMS) was proposed, based on the studies on the agility to cope with the variety of kinds and volume in large volume manufacturing.2. A parallel and serial machine layout was proposed as a system configuration for the proposed FMS and a simulation system was developed for performance evaluation.3. Studies on the economical aspects were performed for HV-FMS and FTL developing models to evaluate the economical performance. The studies with various scenarios for long term demands revealed that HV-FMS is more economical than FTL under varying demands both on kinds and volumes.4. A new control methodology based on the auction method was implemented for the selection and assignment among works, machines and AGVs as an autonomous operating system of the HV-FMS, and its effectiveness was studied for further development of HV-FMS.
