Articles in Press, Accepted Manuscript, Available Online from 09 July 2022

  This paper provides an integrated model for a two-stage assembly flow shop scheduling problem and distribution through vehicle routing in a soft time window. So, a mixed-integer linear programming (MILP) model has been proposed with the objective of minimizing the total cost of distribution, holding ...  Read More

Saeed Khalili; Masood Mosadegh Khah

Volume 7, Issue 3 , September 2020, , Pages 203-220

  This study presents a new mathematical optimization model using queuing theory to determine the hotel capacity in an optimal manner. For this purpose, a Knapsack model based on the queuing theory is proposed. In this regard, after simulating a hotel's reception system with the help of queuing models ...  Read More
