【摘要】 为在保证精度的前提下实现明细表数据有效管理，在基于面向对象建模技术和约束网络理论的基础上，提出了采用通用明细表对产品数据进行管理，并通过约束网络实现从通用明细表到用户明细表的转换，实现了产品明细表的动态存储，减少了大部分的存储量．结果表明，通用产品结构明细表是变型产品设计数据管理的一种有效模式．更多还原

【Abstract】 Bill of materials structures describe the componet structure of a product. Most current bill of material structures have many disadvantages in customer oriented product environment. BOM data would become very large if the product data are describled precisely. A concept of general BOM and constraint model is introduced. A conversion from general BOM to specific BOM is implemented by constraints network. The data model of customer oriented bill of materials is a good tool for data integrating of varied design and product manage system.更多还原
