This research: (1) treats variations in the "design concepts" posed by other members of the design team as "conceptual noise"; (2) shows how to incorporate such noise into "conceptually robust" decisions; (3) describes a method for using the same analysis to provide preference information back to the other team members; and (4) provides a procedure for determining whether to release the conceptually robust design or to wait for further design certainty. Taguchi's approach is used as a starting point because it is widely known. This project generalizes concurrent distributed decision making procedure by employing genetic algorithms. Concurrent engineering processes involve multi-functional teams, which make decisions about many parts of the product\production system and aspects of the product life-cycle simultaneously. This research argues that such concurrent distributed decisions must be based on communications about sets of possibilities rather than single solutions. By extending Taguchi's parameter design concepts, it develops a robust and distributed decision-making procedure based on such communications. That is, it shows how a member of a design team can make appropriate decisions based on incomplete information from the other members of the team.

本研究：（1）探讨“设计概念”的变异 被设计团队的其他成员称为“概念噪音”; (2)显示了如何将这种噪声纳入“概念上的鲁棒性” 决策;（3）描述了一种使用相同分析的方法， 向其他团队成员提供偏好信息;以及 (4)提供了一个过程，用于确定是否释放 概念上稳健的设计或等待进一步的设计确定性。 田口的方法被用作起点，因为它被广泛应用于 知道的 本项目推广了并发分布式决策 采用遗传算法进行程序设计。 并行工程过程涉及多功能 团队，他们对许多部分做出决定， 产品\生产系统和产品生命周期的各个方面 同步 这项研究认为，这种并发 分布式决策必须基于关于集合的通信 而不是单一的解决方案。 通过扩展 田口的参数设计概念，它开发了一个强大的， 基于这种通信的分布式决策过程。 也就是说，它展示了一个设计团队的成员如何 根据不完整的信息作出适当的决定， 团队的其他成员。
