Design Support for "Suriawase" among Several Teams Based on CAD, CAE, Design Knowledge by Agent Technology

日本产品开发的特点之一是产品完整性开发，它可以通过suriawase（日本的设计团队、生产部门、供应商等多个工程师团队从初始设计阶段到细节设计阶段同时进行协商的方式）获得多目标满意的设计解决方案。本研究提出了一种设计支持方法，该方法分为两个阶段。第一阶段采用基于偏好集的设计方法，在不确定设计环境下获得可行的多目标设计域，同时考虑了所有设计者的偏好。设计人员可以将可行的设计域可视化，并在多个设计人员之间相互共享。第二阶段可以显示扩展的设计变量和可能的功能设计领域，如果设计需求领域从第一阶段开始发生变化，可以应用定量依赖关系。本研究提供了几个团队间设计修改的方向建议。在细部设计阶段，设计师能够灵活地适应设计环境的变化。

One of the features of Japanese product development is product integrity development which can obtain a multi-objective satisfactory design solution by suriawase : Japanese way for negotiation among several teams of engineers including design teams, production divisions, and suppliers from the initial design phase to the detail design phase concurrently. This study proposes a design support method for suriawase which consists of two phases. Phase I can obtain feasible multi-objective design domain under the uncertain design environment while incorporating all designers' preference by applying a preference set-based design method. The designers can visualize and share the feasible design domain each other for suriawase among several designers. Phase II can show the expanded design variables and possible design domain for function in case of the change of the design requirement domain from phase I by applying the quantitative dependency. This study provides a suggestion of the direction of design modification for suriawase among several teams. The designers can adapt the change of the design environment flexibly at the detail design phase.
