Fuzzy mathematical models in economics
Fuzzy Sets and Systems, 1988This paper is a survey of three fuzzy mathematical models dealing with economic choice, economic calculation and general economic equilibrium. They are the elements of a fuzzy theory of value. The aim is to test the efficiency of the application of fuzzy subsets theory to the analysis of the foundations of economics and thus to legitimate its use in ...

A large number of tasks in the economy are aimed at processing little formalized data. These can be tasks of analysis, planning, forecasting in the economy. The solution of these problems is reduced to the formalization of the data flow into a functional dependence.

In the article, we analyzed existing methods for assessing the state of complex economic systems using the example of assessing their sustainable development. The analysis includes two parts. The first part is devoted to the classification of existing methods for assessing the stability of the economic system by the number of model parameters, as well ...

Mathematical Modeling of Economic Order Quantity in a Fuzzy Inventory Problem Under Shortages
2018The purpose of this article is to develop an EOQ model to find the optimal order quantity of inventory items where shortages are allowed. Here shortages are uncertain and characterized by triangular fuzzy number and all other parameters like carrying costs, ordering cost, demand and time are considered as crisp numbers.
