1. Continuous Energy Values of 3-Amino-4-Nitraminofurazan Molecule by Modern Optimization Techniques

Ahmet Sahiner; Fatih Ucun; Sumeyya Koman

Volume 9, Issue 2 , Autumn 2017, , Pages 69-77

  The conformational energy values of 3-amino-4-nitraminofurazan (C2N4O3H2) molecule changing with two torsion angles were firstly calculated using density functional theory (DFT) with Lee-Young-Parr correlation functional and 6-31 G(d) basis set on Gaussian Program. And then, these obtained discrete data ...  Read More

2. A fuzzy multi-objective model for a project management problem

S.M. Mirmohseni; S.H Nasseri

Volume 9, Issue 2 , Autumn 2017, , Pages 107-117

  In this research, the multi-objective project management decision problem with fuzzy goals and fuzzy constraints are considered. We constitute α-cut approach and two various fuzzy goal programming solution methods for solving the Multi-Objective Project Management (MOPM) decision problem under ...  Read More

4. Supplier selection among alternative scenarios by Data envelopment analysis

Mohsen Vaez-Ghasemi

Volume 7, Issue 2 , Autumn 2015, , Pages 815-821

  A considerable problem in competitive trade world is choosing the best supply chain. As a result in much more serious circumstances of competitions looking for the best supplier for manufacturing, for preparing raw material, is very significant. Meantime suppliers have different scenarios to be fulfilled, ...  Read More

5. A new approach to fuzzy quantities ordering based on distance method and its applications for solving fuzzy linear programming

S.H Nasseri; E. Darban Jafari; R. Chameh

Volume 7, Issue 2 , Autumn 2015, , Pages 849-855

  Many ranking methods have been proposed so far. However, there is yet no method that can always give a satisfactory solution to every situation; some are counterintuitive, not discriminating; some use only the local information of fuzzy values; some produce different ranking for the same situation. For ...  Read More

6. AIDS Epidemic Modeling With Different Demographic Structures

Agraj Tripathi; Ram Naresh

Volume 7, Issue 1 , Spring 2015, , Pages 785-813

  The most urgent public health problem today is to devise effective strategies to minimize the destruction caused by the AIDS epidemic. Mathematical models based on the underlying transmission mechanisms of the AIDS virus can help the medical/scientific community understand and anticipate its spread in ...  Read More

7. Linear Programming, the Simplex Algorithm and Simple Polytopes

Das Sashi Bhusan; Biswal Bagaban; J.P Tripathy

Volume 6, Issue 1 , Winter 2014, , Pages 702-719

  In the first part of the paper we survey some far reaching applications of the basis facts of linear programming to the combinatorial theory of simple polytopes. In the second part we discuss some recent developments concurring the simplex algorithm. We describe sub-exponential randomized pivot roles ...  Read More
