Global Optimization of Product Design and Manufacturing Using Concurrent Engineering Principles

产品设计和制造涉及整个设计和制造行业的各种团队努力。这些企业所从事的一些工作实现了计算机化和/或自动化，取得了巨大的成就和进步。然而，为了实现进一步的改进，需要设计和制造的新概念和方法，以获得最优的解决方案，该解决方案考虑到并适应从全球角度看待此类项目时可以看到的无数细节。目标之一是构建系统优化方法，巧妙地管理和系统地考虑与产品设计和制造相关的所有因素。本研究的目的，就是要以连续工程的概念和基本理论为基础，研究和发展这种方法，并将其具体的方法和步骤组合起来，以达到上级产品的目的。迄今为止， ...更多信息 为提高并行设计与制造的能力，构建了一套融合多种观点的方法论和实用系统。(1)建立了一种基于多目标优化方法的产品设计决策方法，该方法对与产品设计相关的多个准则进行并行优化。(2)方法和实用系统的构建，以协助群体决策部门之间有不同的，偶尔竞争的要求。(3)（4）为了获得更好的设计方案，提出了一种产品系统的设计优化方法，该方法首先将可行设计区域扩大，有效地扩大了问题的可能解的范围，然后将扩大的区域收缩到最优解的附近。(5)为了使不同工程背景下的上级企业在开发新产品的同时，最大限度地发挥协同效应，构建了虚拟企业新产品协同开发辅助系统。(6)提出了一种并行设计优化方法，该方法将产品的主观美学因素与产品性能、质量、价格等常规客观因素进行并行评价。(7)提出了一种不同部门访问通用设计模型的协同设计方法，通过对模块的操作，重复自顶向下和自底向上的设计过程，得到更复杂的产品设计方案。(8)本文对上述并行设计系统进行了系统的回顾，并将其集成为一个完整的系统，为突破目前工业条件下的障碍和限制提供了基本的方法。少

Product design and manufacturing engages a wide variety of group efforts across the entire spectrum of the design and manufacturing industries. Great achievements and progress have been made by means of computerization and/or automation of some of the various tasks involved in such enterprises. To accomplish further improvements, however, new concepts and methodologies for design and manufacturing are required, to obtain optimurn solutions that take into account and adapt to the myriad of details that can be seen wiuen such projects are viewed from a global perspective. One goul is to construct system optimization methodologies that deftly manage and systematically consider all fartors related to product design and manufacturing. The purpose of this study was to research and develop such methodologies, to assemble concrete methods and procedures, based on concepts of conoinent engineering and its fundamental theories, which aim toward superior pioduds. To date, the followaig fundamenta … More l methodologies and practical systems, incorporating a variety of viewpoints, were constructed in order to improve the capability of concurrent design and manufacturing.(1) A decision making method based on multi-objective optimization methods was constructed, in which a variety of criteria related to the product designs were concurrently optimized.(2) Methodologies and practical systems were constructed to assist group decision making among divisions having different, occasionally competing requirements.(3) System design optimization methods were constructed for designing products that best suit the environment in which they will be used(4) To obtain better design solutions, a design optimization method for product systems was constructed in which feasible design regions are first enlarged, enlarged, effectively multiplying the range of possible solutions to the problem, and then the enlarged regions are contracted in the vicinity of optimum solutions.(5) A system aiding cooperative development of new products in virtual enterprises was constructed so that enterprises, each of which is superior in a different engineering context, can develop new products while maximizing the benefit of synergy effects.(6) A concurrent design optimization method was constucted in which subjective aesthetic factors were concurrently evaluated together with conventional objective factors such as product performance, product qualities and product price.(7) A concument design method where different divisions access common design models was developed in which more complicated product design solutions are obtained by repeating top-down and bottom-up design procedures, using operators acting upon modules.(8) The concurrent design systems note above were systematically reviewed, and integrated into a total system.Fundamental methodologies for breaking through present barriers and limitations with respect to present industrial conditions were accomplished by this study.
