Abstract: To realize preassembly in collaborative environment, models and information needed for different assembly phases were generalized. An assembly information model, organized in a form of assembly knot, was described. Extraction and organization of a function-oriented assembly repository was also presented. The token ring idea was introduced to restrict collaborative activities of assembly design members. In addition, assembly conflict types were analyzed and a six-step assembly conflict-resolution illustration was brought forward. Based on the above primary technologies, the collaborative preassembly system was developed successfully, in which assembly model in an expression of Virtual Reality Modeling Language(VRML),assembly repository in eXtensible Markup Language(XML), and assembly operation in command/parameter. Simultaneously, a preassembly instance was used to illustrate how to solve component contour's conflicts in assembly route layout process.

Key words: collaboration, preassembly, assembly repository, command/parameter mechanism, conflict resolution
