On Application of Two- Stage Stochastic Fully Fuzzy Linear Programming for Water Resources Management Optimization

H. A. Khalifa & M. Al- Shabi · Journal of Advances in Mathematics and Computer Science · 2018

In this paper, a two- stage stochastic fully fuzzy linear programming is developed for a management problem in terms of water resources allocations to illustrate the applicability of a proposed approach. A proposed approach converts the problem into a triple- objective problem an...

An Interactive Approach for Solving Fuzzy Multi-objective Assignment Problems

H. A. Khalifa & M. Al-Shabi · Journal of Advances in Mathematics and Computer Science · 2018

This paper aims to study fuzzy multi-objective assignment (F-MOAS) problem. The problem is considered by incorporating trapezoidal fuzzy numbers. Through the α- level sets, the problem under consideration is converted into the corresponding ( α- MOAS). An interactive approach to...

Solving Investment Problem with Inexact Rough Interval Data through Dynamic Programming Approach

E. E. Ammar & H. A. Khalifa · Journal of Advances in Mathematics and Computer Science · 2015

Finding the best investment is an interesting optimization problem. When we deal with such a problem in an uncertain and vague environment, the optimization problem becomes more difficult. In this paper, we deal with rough data expressed in the form of an inexact rough interval f...
