Strategic Manufacturing Initiative: Constraint Nets for Life Cycle Engineering

生命周期工程是同时考虑 在产品功能、设计、 材料，制造工艺和成本，可测试性， 服务性、质量和可靠性。 由于大多数生命周期 在设计阶段就决定了成本，重要的是， 生命周期信息可供设计师访问， 可以影响产品设计。 该项目研究了一种支持生命周期的新方法 工程，一个涉及使用约束网络 技术，为设计师提供生命周期信息。 约束网络表示约束影响 从产品生命周期的各个方面， 他们必须对产品本身，并必须满足的参数， 整个系统。 有了这样的约束网络， 设计师有一种方法，他可以访问和考虑 产品生命周期所有阶段的信息，例如， 标准和法规、公司政策、制造 能力、可测试性要求、可靠性和 可服务性、成本和交付期限考虑。 该项目是科学家的跨学科奋进， 来自工业界和大学的工程师， 来自主要国家实验室的支持和投入， 程序.

Life-Cycle Engineering is the simultaneous consideration during the product design stage of product function, design, materials, manufacturing processes and cost, testability, serviceability, quality, and reliability. Since most life-cycle costs are dictated in the design phase, it is important that life-cycle information be accessible to the designer so that it can influence product design. This project investigates a new way to support Life-Cycle Engineering, one that involves using constraint network technology to provide the designer with life-cycle information. The constraint network represents the constraining influences from various aspects of a product's life-cycle that exert themselves on the product and must be satisfied by the parameters of the overall system. With such a constraint network, the designer has a means by which he can access and take into account information from all phases of the product life cycle, e.g., standards and regulations, company policy, manufacturing capability, requirements for testability, reliability, and serviceability, and cost and delivery deadline considerations. The project is a cross-disciplinary endeavor of scientists and engineers from industry and the university, with technical support and input coming from major national laboratories and programs.
