A Study on Operating Procedure of Flexible Production Systems

由于全球化的出现、客户需求的多样化和世界经济的不稳定，制造业的营商环境面临着巨大的难题。在这个项目中，认识到为了解决这些问题而提高灵活性的必要性，针对给定的生产设施，研究了一些提供生产系统灵活性的操作功能。这些功能以软件管理包的形式表示。该项目考虑的生产系统包括作为核心领域的柔性制造系统(FMS)，作为装配工厂中流行的设施的流水线生产系统，作为过程工业中经常观察到的设备的批量生产系统。结果以18篇论文的形式发表在期刊和精选的纸质书籍上。1)加载子系统涉及的问题：在这一类中，基于K…开发的柔性制造系统加载程序通过对算法的改进，开发了一个稳健灵活的装车计划系统--Shanker。2)调度子系统关注的问题：与第一类目标相同，通过对实际企业使用的调度程序的研究，开发了一个敏捷有效的作业调度系统。3)集成系统关注的问题：在这一类中，集成了装车和调度功能，并开发了一些操作程序，实现了生产系统的整体性能。4)在业务场景中的有效性检验和定位：基于对柔性相关企业的访谈和问卷调查收集到的信息，对企业期望的柔性内容进行了思考和检验。5)其他贡献：作为一个杂类，讨论了与柔性密切相关的精益/敏捷生产等新兴概念，为提高制造绩效提供了新的方向。作为结束语，本项目通过这些结果为提高柔性做出了一定的贡献。较少

Business environment of manufacturing industries is in a huge pile of tough problems due to emerging globalisation, recent diversification of customer' needs and instability of world economy. In this project, recognising the necessity of flexibility enhancement to cope with these problems, some operating functions providing flexibility of production systems is investigated for the given production facilities. These functions are represented in terms of the software management packages. Considered production systems in this project include flexible manufacturing systems (FMS) as a kernel domain, line production systems as the popular facilities in assembly factories, batch production systems as often observed devices in process industries. Obtained results were published in terms of 18 papers in journals and selected paper books. These are classified into the following categories.1) Loading sub-system concerned issues : In this category, based on the FMS loading procedure developed by K … More .Shanker, a robust and flexible loading planning system, which enables to respond volatile market, was developed through algorithm improvement.2) Dispatching sub-system concerned issues : Aiming the same objective as the first category, an agile and effective job dispatching system was developed through investigation of dispatching procedures used in actual firms.3) Integrated system concerned issues : In this category, both loading and dispatching functions are integrated and some operation procedures, which actualise overall performance of production systems, were developed. Especially, these provide a new focusing stand point of hierarchical planning framework., where dispatching functions should seek optimisation under the constraint of the planning result of loading procedures.4) On their validity check and positioning in business scene : Based on the information collected through interviewing and questionnaire sending to the flexibility concerned enterprises, contents of flexibility the firms are desiring were considered and examined.5) Other contributions : As a miscellaneous category, emerging concepts such as lean/agile production, which are closely related with flexibility, were discussed and a new direction for improving manufactureing performance was provided.As the final remark, this project accomplished a certain contribution for flexibility enhancement through these outcomes.
