Abstract: Changes in the supply chain of one product may affect the price and availability of many other products. Likewise, a product may be composed of a number of smaller parts. Changes in the cost or availability of any of the parts that comprise a product may result in changes in cost or availability of the product as well as many other related products. A supply chain analysis engine is used to model a supply chain. The supply chain analysis engine may identify dependencies between products, sub products, and supply chains. The dependencies may be used to analyze the impact of a change in the supply chain on all relevant products.

Abstract: Various arrangements are presented for performing comparisons of indented cost BOM (bill of material) structures of two or more items in a supply chain management system. By understanding the hierarchical nature of the indented cost BOM structure of each item and various nested relationships, it may be possible to perform complex comparisons that involve multi-level structures.

Abstract: Various arrangements for calculating costs of transferable items in accordance with an iterative periodic average costing model are presented. Indications of a plurality of transfers of transferable items among cost groups of a plurality of cost groups may be received. A plurality of matrices may be created. Elements of each matrix may correspond to iterative periodic average costing equations evaluated for the infinite iteration using the plurality of transfers of transferable items among cost groups and the plurality of cost groups. The cost of each transferable item within each cost group of the plurality of cost groups may be calculated using the plurality of matrices having the elements of each matrix corresponding to the iterative periodic average costing equations evaluated for the infinite iteration.
