Highlights
- Propose a special case of 2E-LRP in cash-in-transit sector combining multiple real-life variants such as multi-echelon, multi-period, capacitated vehicles and distribution centers, different time windows and different conflict objective functions to tackle realistic problems. Then, a mathematical mixed-integer linear programming for this rich LRP is formulated. To the best of our knowledge, this is the first mandatory step to apply the model in real-life problems and, on the other hand, a model with just few constraints even with the best solution approaches cannot be applicable in real-world problems.
- Exploit a solution approach for optimizing the multi-objective mixed integer linear problem with large integer coefficients in order to find the location and number of intermediate facilities among candidate ones, the number of vehicles in each type and in each echelon, the amount of commodities received from the Central Bank and delivered to open logistics center and bank branches/ATMs.
