    One main group of a transportation network is a discrete hub covering problem that seeks to minimize the total transportation cost. This paper presents a multi-product and multi-mode hub covering model, in which the ...

  • Numerical solution of the one dimensional non-linear Burgers equation using the Adomian decomposition method and the comparison between the modified Local Crank-Nicolson method and the VIM exact ‎solution 

    Haghighi, AR.؛ Shojaeifard, M. (Science and Research Branch, Islamic Azad University, Tehran, Iran Website: ijim.srbiau.ac.ir Address: Science and Research Branch, Shohada Hesarak Blvd, Daneshgah Square, Sattari Highway, Tehran, Iran.

  • A two-stage model for ranking DMUs using DEA/‎AHP‎ 

    Rezaeitaziani‎, T.؛ Barkhordariahmadi‎, M. (Science and Research Branch, Islamic Azad University, Tehran, Iran Website: ijim.srbiau.ac.ir Address: Science and Research Branch, Shohada Hesarak Blvd, Daneshgah Square, Sattari Highway, Tehran, Iran.
