In this work is presented the application of qualitative models and statistical methods in quality control of production procedures of various components of an automatic industrial press machine. The methodology of creating a descriptive model of a manufacturing process is presented using qualitative methods of description and a qualitative modeling and simulation application (QMTOOL). The simulation of the model allows the redefinition of the initial machine part specifications and model structure and aims to achieve the most efficient functionality of the production procedures. The final analysis of the simulation results is accomplished using statistical and mathematical methods and applications for the evaluation of the final machine components as well as the production procedures. The important role of the qualitative modeling methodologies and the reliability of the statistical functions used are documented with practical case studies carried out in a machines constructions company.
