Application of ordered fuzzy numbers to modeling of market equilibrium

Summary/Abstract: The paper considers a linear model of market equilibrium in which real numbers are taken as parameters. In the model, it is assumed that demand and supply depend only on price, while other (nonprice related) determinants do not change. However, to get a more realistic model, the author takes into account the impact of other (non-price related) determinants on demand and supply. In this way, a model with fuzzy parameters is obtained, which can be represented by means of ordered fuzzy numbers. In order to determine the fuzzy market equilibrium of such a model, a fuzzy linear system of equations must be solved.
