Fuzzy economic order quantity model with ranking fuzzy number cost parameters [PDF]
Yugoslav Journal of Operations Research, 2012 In this paper, a multi-objective economic order quantity model with shortages and demand dependent unit cost under storage space constraint is formulated. In real life situation, the objective and constraint goals and cost parameters are not precisely

An approach to solve multi-objective linear production planning games with fuzzy parameters [PDF]
Yugoslav Journal of Operations Research, 2018 In this research, n-person cooperative games, arising from multi-objective linear production planning problem with fuzzy parameters, are considered. It is assumed that the fuzzy parameters are fuzzy numbers.

Soft Computing - A Fusion of Foundations, Methodologies and Applications, 2019 The problem of the piecewise linear approximation of fuzzy numbers giving outputs nearest to the inputs with respect to the Euclidean metric is discussed. The results given in Coroianu et al. (Fuzzy Sets Syst 233:26–51, 2013) for the 1-knot fuzzy numbers

On Multidimensional Linear Modelling Including Real Uncertainty
Advances in Electrical and Electronic Engineering, 2014 The theoretical background for abstract formalization of vague phenomenon of complex systems is fuzzy set theory. In the paper are defined vague data as specialized fuzzy sets - fuzzy numbers and there is described a fuzzy linear regression model as a ...

International Journal of Computational Intelligence Systems, 2016 In this paper, the researcher proposed a method to cardinal, median value, variance and covariance of exponential fuzzy numbers with shape function . The covariance used in this method is obtained from the exponential trapezoidal fuzzy number, first by ...

Technological and Economic Development of Economy, 2015 In the present paper, we propose a new approach to solving the full fuzzy linear fractional programming problem. By this approach, we provide a tool for making good decisions in certain problems in which the goals may be modelled by linear fractional ...
