Perishable Shelf Replenishment Using Sales-Triggered Inventory Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inconsistent determination of when to move perishable items from supply rooms to shelf stock in supply chain systems, leading to potential spoilage and inefficiencies.
Innovation Solution
A system that utilizes machine-readable tags on perishable items, a mobile inventory processing device with sensors, and a stock inventory processing device to track inventory levels, historic sales data, and generate real-time alerts for restocking, ensuring efficient replenishment and storage of perishable goods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inventory tracking is used, then device complexity is reduced, but productivity and measurement precision deteriorate due to inconsistent determinations and potential spoilage
Solution Approach 1:
The system enables self-service through automated inventory tracking where the mobile device automatically scans tags, retrieves sales data, calculates restocking values, and generates alerts without requiring manual intervention for each decision, thus improving productivity while managing complexity through automation
Solution Approach 2:
The patent replaces manual mechanical inventory tracking with an automated electronic system that uses mobile devices, sensors, and database queries to track stock levels and generate restocking decisions, substituting human labor with technological systems to enhance efficiency
2Measurement precision
If automated inventory tracking with mobile devices is implemented, then measurement precision and productivity improve, but device complexity increases
Solution Approach 1:
The mobile inventory processing device serves multiple functions including scanning tags, retrieving inventory data, accessing sales history, calculating restocking values, and generating alerts, consolidating these capabilities into a single universal device that improves measurement precision without proportionally increasing complexity
Solution Approach 2:
The system uses a database as an intermediary between the mobile device and inventory data, allowing the mobile device to focus on data collection and alert generation while the database handles storage and complex queries, thus improving measurement precision while managing system complexity through separation of concerns
Data Source
AI summary
System and methods for dynamic replenishment in a facility are disclosed. A mobile inventory processing device reads a machine readable tag affixed to a perishable item and transmits an indication of the perishable item to a stock inventory processing device. The stock inventory processing device retrieves a stock inventory value corresponding to the perishable item and a historic daily sales value for the perishable item from a database. The stock inventory processing device determines a restocking value based on whether the historic daily sales value exceeds the stock inventory value. The stock inventory processing device transmits a second indication to the mobile inventory processing device, The second indication correspond to insufficient shelf stock of the perishable item. The mobile inventory processing device receives the second indication and outputs an auditory alert in response to the second indication.
