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。通过计算机化和（或）自动化这些企业所涉及的一些各种任务，取得了巨大的成就和进展。然而，为了实现进一步的改进，需要新的设计和制造概念和方法，以获得最佳解决方案，考虑并适应从全球角度看待此类项目时可以看到的无数细节。一个目标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有关的所有因素。本研究的目的是研究和发展这些方法，以大陆工程的概念及其基本理论为基础，组合具体的方法和程序，以达到更高的目标。迄今为止，为了提高并行设计与制造的能力，已经构建了更多的方法和实践系统，包括多种观点。(1)构建了一种基于多目标优化方法的决策方法，对与产品设计相关的多种准则进行并行优化。(2)构建了方法和实用系统，以协助具有不同，偶尔竞争需求的部门之间的群体决策。(4)为了获得更好的设计解，构建了一种产品系统的设计优化方法，首先将可行设计区域扩大，将问题的可能解范围有效地乘以，然后将扩大后的设计区域缩小到最优解附近。(5)构建了虚拟企业协同开发新产品的系统，使在不同工程环境下具有优势的企业能够在开发新产品的同时实现协同效应的最大化。(6)构建了一种将主观审美因素与常规客观因素（如产品性能、产品质量、产品价格）并行评价的并行设计优化方法。(7)建立了不同部门访问通用设计模型的连续设计方法，通过操作符作用于模块，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)对上述并行设计系统进行系统审查，并将其整合为一个整体系统。本研究完成了突破目前工业条件下的障碍和限制的基本方法。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.
