Analysis and implementation of the BOM of a tree-type structure in MRPII

According to the character of the tree structure of a bill of material (BOM) in MRPII, a tree-structure storage model has been proposed. It uses two tables to record the parent components and the child components. Each table has a location point combined by three fields. Other link fields in the child component table present the relationship between levels of a product tree. Compared with Gozintograph mode, the BOM design on tree structure has many merits.
