Designing and Solving a Routing Model for Transporting Valuable goods by Considering Route Risk(Case Study: Shahr Bank)

.
One of the main processes in the banking system is the planning and transfer of money from the treasury to the branch and its return to the treasury within a specific and limited time frame. Accordingly, the main goal of most banks is to minimize route risk. Because, daily, a large amount of cash is moved by cash vehicles. In this research, a mathematical model for the transportation of physical money has been developed considering the route risk. In the proposed model, three concepts are presented, which are: 1) the vehicle should not travel long distances in the first three trips because it carries more money, 2) a branch should not be serviced on two consecutive days at the same time 3) A route should not be repeated in two consecutive days. This reduces the possibility of determining a fixed pattern for servicing and increases the security of servicing. Also, a genetic meta-heuristic algorithm has been used to solve the model. In order to show the quality of the algorithm's answer, various problems have been solved in various dimensions of production and with GAMS and MATLAB software. The results show that the genetic algorithm has an average of 0.93% and a maximum of 1.87% difference with the optimal solution in these problems.
