Abstract

Abstract A conceptual tool for inventory cost analysis based on an engineering change request for an item. The invention is a conceptual tool that uses both existing and new product structure in which an engineering change is requested on the item. Based on the product in which the item in question is being used, the system would identify all affected products (active and inactive), evaluate the on- hand inventory costs of raw material and finished products by accessing an inventory database. The system automatically designs an inventory model to evaluate the work-in-process inventory for all products affected by the change through direct access to item and process parameter data from an engineering database. A consolidated inventory cost for raw material, work-in-process and finished goods is derived based on the engineering change request and advises the user of the cost impact.

Claims Analysis

Total Claims: 5

Claim 1

Independent Claim 89 words

An automated method implemented on a computer for evaluating inventory impact due to an engineering change to an item, said method providing for an inventory cost analysis due to the engineering change, said method automatically performing the following steps in response to a user inputing a part number identifying the item affected by the engineering change: retrieving from a bill of materials database all parts affected by the engineering change to the item; and displaying a list of affected part numbers and the costs due to the inventory change.

Claim 2

Dependent Claim 89 words

Claim 3

Dependent Claim 70 words

The automated method as recited in claim 1 wherein the step of retrieving is performed by product group including raw materials, work-in- process inventory and finished goods inventory, said method further comprising the steps of: computing finished goods inventory costs; generating an inventory model and evaluating work-in-process inventory costs; accessing raw material costs; and totaling inventory costs by adding finished goods inventory costs, work-in-process inventory costs and raw material costs.

Claim 4

Dependent Claim 40 words

The automated method recited in claim 2 wherein the step of displaying the list of affected part numbers and the costs due to the inventory change is performed by product group including raw materials, work-in-process inventory and finished goods inventory.

Claim 5

Dependent Claim 61 words

The automated method recited in claim 2 further comprising the step of detemining if other parts are to be tested to provide alternative inventory impact changes due to varied engineering changes and, if so, repeating the steps of retrieving all parts affected by the engineering change and displaying a list of affected part numbers and costs due to the inventory change.
