对中小型机械制造企业中多级树型层次结构产品的数据在微型计算机中存贮问题进行详细讨论，在分析产品树结构的存贮方法的基础上，结合产品结构树的层次结构特点，提出了产品结构数据的分层存贮法和层次矩阵存贮法，解决了品种多变条件下企业上万种产品结构数据的合理存贮问题，为辅助生产管理提供决策服务．
This paper discusses the storage of data of multi-level tree hierarchy products in small and medium-sized machinery manufacturing enterprises in detail in the microcomputer. Based on the analysis of the storage method of the product tree structure, it combines the hierarchical structure characteristics of the product structure tree. The hierarchical storage method and hierarchical matrix storage method of product structure data solve the problem of reasonable storage of tens of thousands of product structure data under the variety of varieties, and provide decision-making services for auxiliary production management.
