Method for predicting asset availability
First Claim
1. A method for predicting asset availability, the method comprising the steps of:
- providing a tag on each asset in a plurality of assets;
emitting a signal from each tag;
sensing with a first antenna when an asset in the plurality of assets arrives at one of a plurality of locations, wherein sensing the asset is accomplished by reading the tag signal with the first antenna disposed at a first angle in a range from 25 degrees to 35 degrees measured from a longitudinal line extending through the first antenna to an imaginary line normal to a wall of a structure at each location in the plurality of locations;
updating a database with an incoming time associated with the asset and the location;
sensing with the first antenna when the asset leaves the location;
updating the database with an outgoing time associated with the asset and location;
calculating a dwell time for the asset at the location by comparing the incoming time and the outgoing time;
updating the database with the dwell time associated with the asset and the location;
predicting availability of the asset based on the incoming time and outgoing time maintained in the database, wherein this step of predicting availability is accomplished by forecasting a forecast amount of assets in the plurality of assets available at the location based on the dwell time associated with the asset in the plurality of assets, and comparing a required amount of assets and the forecast amount of assets to determine whether the forecast amount of assets is sufficient; and
adapting to future asset shortages based on predicted availability of the asset.

Abstract
The present invention is directed to a method for predicting asset availability in a supply chain, whereby assets are typically reusable assets such as packaging or bins which are expensive components yet hard to track. The present invention provides a mechanism for passively sensing when an asset enters or leaves a particular location in the supply chain and updates a database accordingly. This location and timing information is thereafter used in the present invention to model future movement of the assets for use in predicting whether a sufficient amount of the assets will be present at any particular location in the supply chain at any particular point in the future. An alert is generated if the modeling determines an insufficient amount is modeled to be present at the particular location. This allows a decision maker to make adjustments to ensure a sufficient amount of assets will be present at the particular location.
