Entropy-based multi-item solid transportation problems with uncertain variables
Dalman, Hasan (SPRINGER, ONE NEW YORK PLAZA, SUITE 4600 , NEW YORK, NY 10004, UNITED STATES, 2019)This paper focuses on modeling and optimization of entropy-based uncertain multi-item solid transportation problems (MISTPs), in which direct costs, supplies, demands, conveyance capacities are uncertain nature. The purpose ... -
Interactive goal programming algorithm with Taylor series and interval type 2 fuzzy numbers
Dalman, Hasan; Bayram, Mustafa (SPRINGER HEIDELBERG, TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2019)This paper presents an interactive fuzzy goal programming (FGP) approach for solving Multiobjective Nonlinear Programming Problems (MONLPP) with interval type 2 fuzzy numbers (IT2 FNs). The cost and time of the objective ... -
Multi-objective Solid Transportation Problem in Uncertain Environment
Dalman, Hasan; Sivri, Mustafa (SPRINGER INT PUBL AG, GEWERBESTRASSE 11, CHAM CH-6330, SWITZERLAND, 2017)Although new information technologies decrease information and transaction costs, transportation problem of physical goods is still relevant. Globalization of trade increased the uncertainty that companies are facing, ... -
A simulation algorithm with uncertain random variables
Dalman, Hasan (Ramazan Yaman, 2018)In many situations, uncertainty and randomness concurrently occur in a system. Thus this paper presents a new concept for uncertain random variable. Also, a simulation algorithm based on uncertain random variables is ... -
Some Properties of Pessimistic and Optimistic Values For Uncertain Random Variables
Dalman, Hasan (YILDIZ TECHNICAL UNIV, YILDIZ CAMPUS, BESIKTAS, ISTANBUL 34349, TURKEY, 2018)The optimistic and pessimistic values of uncertain random variable have been presented for handling both uncertainty and randomness. In this paper, some extensions of optimistic and pessimistic values of uncertain random ...
