工程更改研究进展

在产品的生命周期里，多元化的客户需求、生产制造技术工艺的改进等，不断对企业提出新设计更改的要求。在 现有的产品设计信息基础上对产品进行工程更改，是满足复杂多变的市场的重要方法。在研读国内外文献基础上，根据 工程更改中的研究对象不同，从工程更改的过程管理和更改传播技术2个方面对工程更改理论进行归纳概括。从工程 更改的定义、原因、管理原则、产品的生命周期和计算机支持下环境的更改管理系统、更改机制、更改经验，利用零部件间 参数关系、多层网络模型和设计结构矩阵等更改传播的技术等多方面总结了工程更改的理论研究。最后提出未来工程 更改的研究重点是更改管理系统和传播技术与实际应用的结合，在不断应用过程中完善理论。

Review of Engineering Change

Enterprises have to change their design because of customers' multi-requirements and improvement of manufacturing process in product life cycle. In order to meet the customer requirements, engineering change is inevitable and is one of the important parts in product design. Based on literatures and different objectives, theories of engineering change from two aspects process management and communication techniques were summarized. It is also summarized from the definition and principle of engineering change, the engineering change management system supported by computer in product life cycle, the change experience. the parameter relationships between components, multilayer network model and design structure matrix change propagation technology. And the next research emphasis is to improve change management system and change propagation technology in the process of practical application.
