摘要: | 工程变更是资讯产品生命周期中无可避免且必要之程序,其中的零件变更更是企业维持资讯产品竞争力的有利因素之一。然而,充份提供管理者所需资讯,及良好的决策支援沟通工具,以解决沟通不良的问题,是提升零件变更处理效率的先决条件。此沟通系统应具备两方面的能力:(1)设计与制造资讯间的连结机制,以完整提供变更前后之资讯,并维持其一致性(2)提供工程变更决策程序沟通管道,以免部门间之观点差异,造成决策程序的冗长无效率。因此,本研究从资讯系统规划,与作业执行的观点,提出工作经验与看法,做为比较与参考。 在资讯系统规划阶段,利用资料流程图规划。此规划方法是将变更资料,有系统的转换为资料档或图档,以免除传统以人工转换,所造成的设计/制造资讯的不一致及无效率。此法应用群组装配的概念,将装配程序考虑到途程上以缩减流程,可以简化文书作业的处理,并且减低MRP受变更料件变动的影响;同时,这个规划程序可以在变更前,提供有关工程变更相关料件,及变更件对排程的影响评估资讯,在变更后易于快速的更新设计与制造资讯,以维持其一致性。 在作业执行面方面,本研究提出实际作业流程之说明,提供参考。此流程是经由多项零件变更关键资讯的决定与提供,并且配合各软体功能不同的考虑而决定,以提供管理者零件变更决策支援的沟通管道,有助于提升零件变更执行之效率与决策品质。此外,经由资讯规划面与执行面的决策支援程序之相互配合与参照,可以使零件变更在资讯及程序上,达到充分沟通的目的,进而提升零件变更评估与执行效率,并且有助于维持设计与制造资料的一致性。 Engineering change is the essential and inevitable process to IA product. Rapid and efficient process of proceed Component change is one of favorable Engineering change factors for enterprise keep their product's competitiveness. However, the prerequisite condition that raise the efficiency of process component change is offer the component change keeper sufficient information and well communication system of decision making. This system should provide with : (1)the connect system between design and manufacture information, and consistence before and after change.(2) offer the channel of Engineering Change decision making to avoid long and inefficiency process because of individual unit disagreement of opinion. So, we offer the solution through information system planning and operation for reference. In the stage of planning, we use Data Flow Diagram (DFD).To convert change information to database or figure file, free of mistake by design and manufacture manual work. This concept contain group assemble, to shorten process and paper working also reduce the change impact on MRP system and offer the impact information of scheduling. In the stage of operation, we offer the attention of process for reference. This attention of process composed of many change operation key information and software function. It not only raise the efficiency and quality of change implement but also the communication support system of keeper's decision making. Besides, we can keep the consistence of design and manufacture data through information system planning process and implement support system. |
