The characteristic of the fuzzy model among operating modules

Piech H., Machura M.

In this paper we refer to models characterizing successive use of means in indirect modules. Intermodular flow balance is characterized by Leontief's model. On its basis it is possible to estimate the initial value, indirect operating levels and the final value. In existing publications we deal with deterministic knowledge relating to initial, final and transferred values. In this paper we will take the mentioned parameters as fuzzy parameters. The problem is set to find a simple and fast method to select optimal parameters from fuzziness ranges for which the assumed criteria will be fulfilled. One of the criteria can be the minimal initial value, the maximal final value or the minimal diffusion of operation.

Metoda oceny współczynników kapitałochłonności w okresie prognozowanym

Zaprezentowano metodę oceny elementów macierzy współczynników kapitałochłonności w dynamicznym modelu Leontiefa.

A method of estimating the elements of the matrix of capital intensity coefficients in a dynamic model of input-output relations in the forecast period has been presented. In the presents method, the estimations of these elements have been treated as the realizations of a stochastic process, generated by the representation of the process which is determined by the eigenvalues and eigenfunctions of the Freedom integral equation of the second kind.
