A new queuing-based mathematical model for hotel capacity planning: a genetic algorithm solution

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
