Abstract
  Investment problem is one of the most important and interesting optimization problems. This problem becomes more difficult when we deal with it in an uncertain and vague environment with chaos data. This paper attempts to study the investment problem with uncertain return data. These data are represented ...  Read More

Volume 5, Issue 4 , December 2018, , Pages 296-305

https://doi.org/10.22105/jarie.2018.151038.1058

Abstract
  In this paper, an interactive approach for solving multi- objective nonlinear programming (MONLP) problem is introduced. This approach is combined with the Reference Direction (RD) introduced by Narula et al. (1993) and the Attainable Reference Point (ARP) method introduced by Wang et al. (2001). In ...  Read More

Fuzzy optimization
On solving fully fuzzy multi-criteria De Novo programming via fuzzy goal programming approach

Volume 5, Issue 3 , November 2018, , Pages 239-252

https://doi.org/10.22105/jarie.2018.148642.1054

Abstract
  In this paper, a Multi-Criteria De Novo Linear Programming (F- MDNLP) problem has been developed under consideration of the ambiguity of parameters. These fuzzy parameters are characterized by fuzzy numbers. A fuzzy goal programming approach is applied for the corresponding multi-criteria De Novo linear ...  Read More

Volume 5, Issue 2 , September 2018, , Pages 110-121

https://doi.org/10.22105/jarie.2018.139816.1045

Abstract
  In this paper, a Fuzzy Multi-Objective Linear Programming (FMOLP) problem having both objective functions and constraints fuzzy parameters is introduced. Theses fuzzy parameters are characterized by trapezoidal fuzzy numbers. The FMOLP problem is converted into the corresponding deterministic MOLP problem ...  Read More
