Deciding Parameter Values with Case-Based Reasoning

This paper describes an industrial application of case-based reasoning (CBR) in the aluminium die-casting industry: the setting of parameters of a pressure diecasting machine for a specific die. As well as describing the application, the paper shows how the system has evolved. The use of cases has given the system a flexibility which has enabled it to be used in ways that were not foreseen at the outset of the project. The pressure die-casting application is a good example of a common problem: the correct setting of system parameters depending on a set of input values. The paper discusses the general use of CBR for deciding on parameter values, and describes the lessons that have been learned through the construction of the die casting parameter setting system.
