Inventory Valuation via Stage-Specific Identifier Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional inventory management systems fail to account for unfinished goods in the production process, leading to incomplete asset valuation as these goods are not considered until they are fully completed and added to the finished goods stock, resulting in an incomplete picture of asset value.
Innovation Solution
Assigning identifiers to goods entering the production process that contain information about their stage and characteristics, allowing for tracking and valuation of goods in progress through regular updates, with each stage having a designated price based on the value added, enabling comprehensive valuation of all goods, including raw materials, unfinished products, and finished products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional inventory management systems are used to track only raw materials and finished goods, then the system simplicity is maintained, but the asset valuation completeness deteriorates because Work in Progress items are not accounted for
Solution Approach 1:
The production process is divided into discrete stages, with each stage assigned a specific identifier and valuation price. This segmentation allows WIP items to be tracked at each production stage rather than only at raw material and finished goods levels, improving asset valuation completeness while maintaining manageable system complexity through structured breakdown
Solution Approach 2:
An intermediary computer system is introduced that automatically tracks and values WIP items by receiving data from production stages and calculating valuations based on assigned prices. This intermediary handles the complexity of WIP tracking, allowing the overall system to achieve complete asset valuation without requiring manual intervention at each production stage
2Measurement precision
If manual tracking of Work in Progress items is implemented, then the asset valuation completeness improves, but the labor requirements and operational complexity increase
Solution Approach 1:
The system enables self-service tracking where WIP items automatically generate and update their own identifiers as they move through production stages. Detectors and sensors at each stage automatically capture item movement and trigger valuation updates without manual intervention, achieving accurate inventory tracking while simplifying operations
Solution Approach 2:
Manual mechanical tracking of WIP items is replaced with automated electronic detection systems and computer-based valuation calculations. The computer system automatically calculates valuations by multiplying quantity of items at each stage by their assigned prices, eliminating manual counting and calculation while improving tracking accuracy
3Measurement precision
If identifiers with detailed stage information are assigned to each item, then the valuation accuracy improves, but the data processing complexity increases
Solution Approach 1:
Each WIP item receives an identifier with stage-specific information appropriate to its current production stage. The identifier contains only the necessary valuation data for that specific stage, not all possible production information. This local quality approach maintains valuation accuracy by providing stage-appropriate detail while reducing overall data processing complexity through selective information capture
Solution Approach 2:
The system dynamically changes the parameters stored in identifiers based on the production stage. As items move through stages, only the relevant valuation parameters are updated and maintained in the identifier. This parameter change strategy ensures valuation accuracy by maintaining appropriate stage-specific data while minimizing data processing complexity by avoiding storage of all possible parameters throughout the entire production process

AI summary
Methods and computer systems are provided managing and valuating inventory. In one embodiment, a computer system may assign every item of goods which is entering a working process to an identifier. The computer system may then track the goods in the working process. Further, the computer system may update a given identifier when the goods assigned to this identifier enter another stage in the working process, assign at least one price to each stage in the working process, determine the content of one or more identifiers, and calculate a price for goods in the working process.
