Fuzzy logic in rationalization of production systems on the basis of simulation project

The present paper presents a systemic approach to foundry management. Thanks to production process modelling and simulation techniques, an attempt was made to synthesise many interconnected devices and numerous manufacturing stages into one production system. The sheets of multi-criterion evaluation were prepared, where criteria and variants were assessed by means of subjective point evaluation and fuzzy character evaluation. The paper presents an analysis example of finishing activities of castings realized in foundry and in cooperation.
