Supply management system
First Claim
1. A data processing system comprising:
- a stock level data store containing stock level data for an item comprising current stock level data, stock demand data and stock replenishment data;
at least one processor coupled to the stock level data store; and
storage media coupled to the at least one processor and containing programming code for causing the at least one processor to perform processing comprising;
calculating predicted stock level data for said item using said current stock level data, said stock replenishment data and said stock demand data, said predicted stock level data comprising a date and/or time and a predicted number of stock units available for meeting a demand for the item at said date and/or time; and
graphically outputting changes in the predicted stock level data over a future period of time.

Abstract
A data processing system comprises a stock level data store for storing stock level data for a stock item or part comprising current stock level data, stock demand data and stock replenishment data; a program store storing code for a processor; and a processor coupled to the data store for accessing the stored data and coupled to the program store for implementing the stored program code. The code causes processing comprising calculating predicted stock level data using the current stock level data, the stock replenishment data and the stock demand data, said predicted stock level data comprising a date and/or time and a predicted number of stock units available for meeting a demand for the stock item or part at said date and/or time, and, graphically displaying changes in the predicted stock level data over a future period of time. The data processing system assists a supplier in planning inventory management, allows a supplier to predict when there is a risk of letting a customer down, and allows a supplier to estimate the effect of a batch of work-in-progress not being completed on time.

8. A stock planning tool to graphically output predicted stock level changes for an item over a period of time, the stock planning tool comprising:
-
computation means to calculate a predicted stock level for the item at a future time by adding an initial stock level to a predicted cumulative additional stock level at the future time and subtracting a cumulative stock demand at the future time; and
graphing means, in communication with said computation means, for providing a graphical output of variations of said predicted stock level over time. - View Dependent Claims (9, 10, 11, 12, 13)

14. A supply planning method for assisting identification of a potential date and/or time at which there is a risk of a level of stock of an item falling below a threshold value, the method comprising:
-
reading initial stock level data from a data store, the initial stock level data comprising data indicating an initial stock quantity of the item;
reading customer demand data from a data store, the customer demand data comprising data indicating at least one order for a demanded quantity of the item and a corresponding date and/or time for meeting the order;
reading stock replenishment data from a data store, the stock replenishment data comprising data indicating at least one stock replenishment event increasing a stocked quantity of the item at a corresponding date and/or time;
calculating a cumulative item demand at a future data and/or time by summing demanded quantities data of the item preceding said future date/time;
calculating a cumulative stock level at a future data and/or time by summing said initial stock quantity and increases in stocked quantity of said item preceding said future date and/or time;
calculating a predicted level of stock by subtracting said cumulative item demand from said cumulative stock level;
repeating said predicted level of stock calculation for a plurality of different future dates and/or times; and
graphically outputting a plurality of predicted levels of stock for a corresponding plurality of different future dates and/or times.
