Development of a multi-objective model for the routing problem of vehicles carrying valuable commodity under route risk conditions (Case study of Shahr Bank)

Mohammad Shafiekhani; Alireza Rashidi Komijan; Hassan Javanshir

Articles in Press, Accepted Manuscript, Available Online from 27 June 2023

  In this paper, a new type of vehicle routing problem in the valuable commodity transportation industry is modeled considering the route risk constraint. The proposed model has two objective functions for risk minimization. In the first objective function, three concepts are presented, which are: 1) the ...  Read More

Optimizing the routing problem in the vehicle carrying cash considering the route risk (case study of Bank Shahr)

Mohammad Shafiekhani; Alireza Rashidi Komijan; Hassan Javanshir

Volume 11, Issue 1 , February 2024, , Pages 143-154

  The process of transferring money from the treasury to the branches and returning it at specific and limited periods is one of the applications of the Vehicle Routing Problem (VRP). Many parameters affect it, but choosing the right route is the key parameter so that the money delivery process is carried ...  Read More

Integration of two-stage assembly flow shop scheduling and vehicle routing using Improved Whale Optimization Algorithm

Vahid Bahmani; Mohammad Amin Adibi; Esmaeil Mehdizadeh

Volume 10, Issue 1 , March 2023, , Pages 56-83

  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

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
