1. A forecasting system for predicting demand for products produced by a manufacturing line, the forecasting system comprising:
- a database for storing information related to the volume of orders for products produced by the manufacturing line, wherein there is a plurality of types of products produced by the manufacturing line;
a knowledge base for storing rules relevant to forecasting demand for the products produced by the manufacturing line;
a test knowledge base for storing proposed rules for forecasting demand for the products produced by the manufacturing line; and
a program interface, coupled to the data base, the knowledge base and the test knowledge base, for providing a user interface to the database, the knowledge base and the test knowledge base, the program interface includinggenerating means, coupled to the data base and the knowledge base, for generating forecasts of the future product demand for the products based on the rules stored in the knowledge base and the information stored in the data base,displaying means, coupled to the generating means, for displaying the forecasts generating by the generating means,simulation means for allowing generation of test forecasts using the proposed rules stored in the test knowledge base operating upon the information stored in the database, andupdating means, coupled to the data base and the knowledge base, for updating the database and for updating the rules stored in the knowledge base, wherein updating the rules results in changing the forecasts generated by the generating means.

Abstract
A forecasting system predicts product demand. A database stores information related to the volume of orders for a plurality of products. A knowledge base stores rules relevant to the products. A single program interface accesses the database and the knowledge base, including access screen means for monitoring and for updating the database and the knowledge base, the single program interface also including access screen means for generating forecasts of the future product demand for the products.

4. A method of using a knowledge base to forecast product demand for products produced in a manufacturing environment, including the steps of:
-
(a) collecting in a computer database, sales volume information for the products; (b) generating a reference forecast for the product demand using the sales volume information for the products collected in step (a) and using a first set of rules within a knowledge base; (c) storing the reference forecast; and
,(d) generating a test forecast for the product demand using the sales volume information for the products collected in step (a) and used in step (b) to generate the reference forecast, the test forecast being generated using a second set of rules within the knowledge base. - View Dependent Claims (5, 6, 7, 8)
