A Step Entity Control System for Concurrent Engineering: SECS/CE

小行星9224783 这是一个为期三年的连续奖励的第一年资助。 该项目正在设计和建立一个原型存档和版本控制系统，通过允许工程师协调对设计的并行更改来促进并行工程。 该系统允许工程师合并并发变更，发现并发变更之间的冲突，询问变更和设计的内容，并解决并发变更产生的设计版本之间的冲突。 该系统使用STEP标准的EXPRESS语言对设计内容进行建模，用于工程产品数据的交换。 EXPRESS模式由存档和版本控制系统以及设计版本本身管理，以便系统的各种工具可以访问数据及其模式。 该系统将通过支持工程师之间的协作，大大推进并行工程和制造的数据管理基础设施，因为他们同时从事产品设计。 ***

9224783 Hardwick This is the first year funding of a three-year continuing award. This project is designing and building a prototype archive and version control system that facilitates concurrent engineering by allowing engineers to coordinate concurrent changes to a design. The system permits engineers to merge concurrent changes, find conflicts between concurrent changes, ask questions about the contents of changes and designs, and resolve conflicts between design versions produced by concurrent changes. The system models the contents of a design using the EXPRESS language of the STEP standard for the exchange of engineering product data. The EXPRESS schemas are managed by the archive and version control system in addition to the design versions themselves so that the various tools of the system have access to both the data and its schemas. The system will significantly advance the data management infrastructure for concurrent engineering and manufacturing by supporting collaborations between engineers as they concurrently work on the design of products. ***
