Abstract:

A case study of rule knowledge base on developing stress relaxation in welded components is presented in the paper. The procedure of simplified decision support model formulation – including expert knowledge externalization, formalization of knowledge, the selection of variables and identifying domain of attributes is described. A decision tree was used to support creating and visualizing of the model. The result of the work is a set of rules constituting a simplified model to predict the stress relaxation parameters of stress-relief annealing applied to welded components of PZL-10W helicopter engine produced by WSK Rzeszów. Developed application can be implemented in one of the reasoning system shells.
