Viewing the Supply Chain Data Model

Once the data is in the database, it can be shown in the SCMB user interface as the supply chain data model (extended bill of material and related details). A supply chain data model is a representation where a supply chain is depicted by relationships between its component data elements. This provides a quick and simple way to get insight into a complex supply chain. The purpose of this is twofold: to calculate some simple performance measures without the need of detailed simulation; to quickly validate the underlying supply chain data model (data relationships) and values before creating the Arena simulation model.

Two different ways/models for the graphical representation of the supply chain data structure are considered. The first one is a model based on the product structure, which is an extension of the Bill of Materials (BOM). The second is a model based on the relations of suppliers for material flows.

The following diagram shows an example of a supply chain data model. The left panel shows the expanded bill of material. It can be expanded or contracted in the usual way, by clicking on the plus or minus symbols. For the selected (highlighted) item in the tree view, a list view at the top frame of the right side shows the product structure for the selected product. A list view at the bottom frame of the right side indicates the detailed component/material supplier information.
