【摘要】：精益生产在当今市场竞争激烈的环境中越来越被各个行业,尤其是制造业所认可并成为一种科学的生产管理模。在我国改革开放的宏观背景之下,精益生产的思想被引入到国内,一些大中型企业积极学习与效仿精益生产方式。在不断学习的同时,一些企业与专家学者也开始了对精益理论广泛应用的研究。国内外对精益理论的研究目前大多数都集中在三个方面：一是对于丰田精益生产理论的研究与发展；二是将精益生产理论应用在制造行业的研究,例如汽车、阀门、发动机等制造领域；三是将精益生产理论应用到其它非制造行业的研究。对于精益理论在产品开发设计阶段的研究尚处于起始的阶段。本文基于对精益理论在生产制造领域的认识归纳出在产品研发与设计过程中会产生的浪费的十二种类型,即：文件与数据传递的浪费;过度的质量要求；等待；过多的重复性任务：经常出现的启动与停止：非标准化的浪费：重新创造的浪费；缺乏系统的执行准则；经常改变的流程与目标；生产阶段的技术修改；一次性发布大量数据；非并行结构的设计流程。在此基础上,本文通过应用价值流理论定义出在A企业产品开发与设计的过程中存在的浪费类型,并将流程从纸面上的文字转化为反映产品开发与设计中的价值流图,用图示的方式将每个流程用供方、输入、流程、输出以及客户这五个方面来表示并从中分析出流程中的不增值项。本文还介绍了A企业进而针对在产品开发与设计阶段的浪费与不增值项所采用的Creo参数化设计、Windchill PDM Link文件管理软件、标准化、可视化、A3报告以及TPM等精益工具或由精益思想得出的有效方法以及这些工具和方法的优势,并得出了应用这些方法可以消除A企业在产品开发与设计中的浪费,同时培养相关员工在设计与研发活动中的精益思维方式,为A企业产品开发与设计流程不断更新与改进奠定了基础的结论。本文还对精益产品开发与设计应用于非标产品的研究提出了展望。在产品生产制造之前的开发与设计流程,能影响最终的生产成本,并且只有在产品开发与设计阶段中,才能使产品获得竞争优势的机会最大化的得到提升。为此,研究精益产品开发与设计理论,使其与其它理论相结合,或是将精益理论软件化,在方便企业使用的同时,也使精益理论以一种可视化的方式呈现在学习者和使用者面前。
[Abstract]:Lean production is more and more recognized by various industries, especially manufacturing industry, and has become a kind of scientific production management model in today's competitive market environment.Under the background of China's reform and opening up, lean production is introduced into China, and some large and medium-sized enterprises actively learn and emulate lean production.At the same time, some enterprises and experts have begun to study the wide application of lean theory.At present, most of the researches on lean theory at home and abroad are focused on three aspects: first, the research and development of Toyota lean production theory; second, the application of lean production theory to manufacturing industry, such as automobile, valve, etc.The third is the application of lean production theory to other non-manufacturing industries.The study of lean theory in product development and design stage is still in the initial stage.Too many repetitive tasks: recurring startup and discontinuation: non-standardized waste: wasteful re-creation; lack of systematic implementation criteria; frequently changed processes and goals; technical changes in the production phase; one-time release of large amounts of data;Design flow of non-parallel structure.On this basis, this paper defines the waste types in the process of product development and design of enterprise A by applying the theory of value flow, and converts the flow from the words on the paper to the value flow graph that reflects the product development and design.Each process is represented and analyzed in terms of supplier, input, process, output and customer in a graphical manner.This paper also introduces the Creo parameterized design of windchill PDM Link file management software, which is used by Enterprise A for waste and no value added in the stage of product development and design.Visual A3 reports and lean tools such as TPM or effective methods derived from lean ideas, and the advantages of these tools and methods, and the application of these methods can eliminate waste in product development and design in enterprise A.At the same time, we cultivate the lean thinking mode in the design and R & D activities, which lays a foundation for the product development and design process renewal and improvement of Enterprise A.The research prospect of lean product development and design in non-standard products is also presented in this paper.The process of development and design before product production and manufacture can affect the final production cost, and only in the stage of product development and design, can the product get the most opportunity to gain competitive advantage.Therefore, we study the theory of lean product development and design, combine it with other theories, or software lean theory, which is convenient for enterprises to use.Lean theory is also presented to learners and users in a visual way.
