Embodiment Construction

[0047] The manufacturing BOM generally comes from the design BOM / process BOM. This paper implements the conversion algorithm from EBOM / PBOM to MBOM based on the new set relationship. This algorithm is performed on the BOM instance object in the memory, and the BOM instance is generally an object-oriented data model or a semi-structured data model.

[0048] Step1. Obtain a copy of EBOM / PBOM and assign its root node to TempNode,

[0049] Step2. Establish linked lists CoopParts, VirtualParts and SemiParts;

[0050] Step3. Traverse all child nodes ChildNodes of TempNode, assign each node of ChildNodes to SonNode, and judge the ItemType property of SonNode:

[0051] 1) If it is "Outsourcing" or "Procurement", add the node SonNode in CoopParts;

[0052] 2) If it is "virtual", add the node SonNode in VirtualParts;

[0053] 3) If it is "blank", add the node SonNode in SemiParts;

[0054] Step4. Traverse CoopParts: get the i-th CoopPart in CoopParts, and delete the CoopPart node in...

Abstract

The invention discloses a method for producing BOM (Bill of Material) memory model building based on XML (extensive markup language). According to the method, BOM aggregation relationship is redefined, BOM memory model building based on XML is innovatively proposed, the problems of high redundancy and low execution efficiency are solved, ideal experimental effects are achieved according to experimental verification, and new methods and thoughts are proposed in terms of BOM memory model building.

Description

technical field [0001] The invention relates to a method for building a BOM storage model, in particular to a method for building a manufacturing BOM storage model based on XML. Background technique [0002] Multi-variety and small-batch production has become an important production mode for current manufacturing enterprises due to its high flexibility and strong adaptability. In this production mode, many parts are borrowed, and engineering changes are relatively frequent; the same group of parts may form different parts in the BOM due to different assembly locations and models; and although a part can only have one BOM in memory structure, but its storage model may have multiple BOM structures with different versions, views or validity periods. Therefore, in fact, the storage model of BOM is different from the BOM instance of the tree structure in the memory, and it is actually a "graphic structure". [0003] There are two main types of BOM information: one is the attrib...
