- Abstract
Problem observed in this research is inspired by distribution of parcels in courier service where city area is divided into service zones based on the historical data of deliveries intensities and city structure. Each service zone is served by own vehicle of known limited capacity. Number of deliveries per zone varies between days, where average intensity is known in advance. Additionally, total number of deliveries can exceed capacity of the vehicle. All exceeded deliveries in service zones must be served by the "sweep" vehicle. Main idea of our paper is to evaluate the impact of fixed and flexible zoning strategies on total traveled distance of vehicles in the parcel distribution. In fixed zoning strategy deliveries cannot be transferred, whereas in flexible zoning these deliveries can be transferred between zones. For the purpose of solving problems of realistic size we use heuristics approach, while Mixed Integer Programming (MIP) model was developed to solving the small scale problems.
