      Shojaeibarjouei, Abolfazl; Barabadi, Abbas; Tavakkoli-Moghaddam, Reza (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      In this paper, we present a new mixed-integer linear goal programming (MILGP) model for a fuzzy single-source capacitated facility location problem (F-SSCFLP), in which demands are considered as triangular fuzzy values and capacity of facilities are fuzzy constraints. At first, the basic fuzzy model for the given problem is presented. Then, utilizing goal programming (GP) approach and fuzzy principals ...
    • Non-Preemptive Open Shop Scheduling Considering Machine Availability 

      Shojaeibarjouei, Abolfazl; Barabadi, Abbas; Tavakkoli-Moghaddam, Reza (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      This paper considers a non-preemptive open shop scheduling problem (OSSP), in which machines are not available to process jobs on known periodic interval times resulted from periodic service repair, rest period, and so on. Asymmetric transportation time between machines is considered, which can be different from one job to another. The objective is to minimize the weighted mean completion time (WMCT). ...
