The article „An interactive algorithm for large scale multiple objective programming problems with fuzzy parameters through TOPSIS approach“, by authors Mahmoud A.ABO-SINNA, Tarek. H.M.ABOU-EL-ENIEN,published in YUJOR, Vol 21, No 2, 2011, was retracted at the request of the editors because the authors infringed professional codes by submitting the above article to YUJOR after their substantialy the same article, with the same title „An interactive algorithm for large scale multiple objective programming problems with fuzzy parameters through TOPSIS approach“, was accepted for publication and published in another journal, Applied Mathematics and Computation,Volume 177, Issue 2, 15 June 2006, Pages 515–527. Članak “AN INTERACTIVE ALGORITHM FOR LARGE SCALE MULTIPLE OBJECTIVE PROGRAMMING PROBLEMS WITH FUZZY PARAMETERS THROUGH TOPSIS APPROACH”, autora Mahmoud A.ABO-SINNA, Tarek. H.M.ABOU-EL-ENIEN, štampan u YUJORu, Vol 21, No 2, 2011, povlači se na zahtev urednika jer su autori prekršili profesionalni kodeks podnoseći navedeni članak redakciji YUJORa, iako se on najvećim delom preklapa sa njihovim člankom pod istim naslovom „An interactive algorithm for large scale multiple objective programming problems with fuzzy parameters through TOPSIS approach“, a koji su isti autori već dostavili i publikovali u časopisu Applied Mathematics and Computation,Volume 177, Issue 2, 15 June 2006, Pages 515–527.
