PORÓWNANIE ROZWIĄZANIA UKŁADÓW RÓWNAŃ LINIOWYCH O PARAMETRACH ROZMYTYCH OPISANYCH WYPUKŁYMI I SKIEROWANYMI LICZBAMI ROZMYTYMI NA PRZYKŁADZIE MODELU RÓWNOWAGI CZĘŚCIOWEJ
COMPARISON OF SOLUTIONS SYSTEMS OF LINEAR EQUATIONS WITH THE PARAMETERS DESCRIBED BY CONVEX FUZZY NUMBERS AND ORDERED FUZZY NUMBERS EXEMPLIFIED BY THE PARTIAL EQUILIBRIUM MODEL

Summary/Abstract: The paper describes the partial equilibrium model for two goods, leading to a system of linear equations. The system of linear equations with the parameters represented by convex fuzzy numbers (CFN) and ordered fuzzy numbers (OFN) have been considered. In both cases, such systems can be solved by applying α-cuts and interval arithmetic. Additionally, the conditions of existence of solution have been presented.
