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

Hamiden Abdelwahed Khalifa

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

  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
