These algorithms have laid a foundation for setting up the basic data in MES. The five elements BOM definition used to describe product structure is given in order to reduce BOM quantity and realize BOM consistency effectively. In addition, the mapping algorithm is implemented by five elements BOM, which can make them link seamlessly to transforming from product structure model to procedure model with workflow. It provides a technical foundation to control and management in the product life cycle. And it also meet requirements which include the identicalness, integrality, integration of BOM data in the product life cycle.
