The Optimization of Trucks Fleet Schedule in View of Their Interaction and Restrictions of the European Agreement of Work of Crews

Abstract

The importance of compliance with the schedule of work of road trains on the highway transport network of the European Union is shown. The possible options for work and rest modes for truck drivers on international routes have been analyzed. A model for optimizing the truck fleet operation plan has been developed. This model has two levels, that is, the general graph contains subgraphs designed with incompatible vertices to determine the active and shortest schedule. Each of the subgraphs reflects alternative routes and schedules of a truck. The model also includes restrictions on the total cycle time and active period duration of available unloading points. To find the shortest schedule, integer programming with a guaranteed optimal solution was applied. Testing of the proposed algorithm was performed for the example of serving orders for international freight transportation between the cities of Ukraine, Poland, and the Czech Republic. The active schedule is based on the criterion of the minimum of the total duration of drivers' work. The results obtained are valid, consistent with the rules of the European Agreement. They indicate that the choice of the best schedule for a single car on a unitary route is not the best solution for the entire truck fleet and the entire flow of orders.

Cross-docking cargo delivery routing for guaranteed minimum period

“…The limitation (12) means that the total number of flows ending in each j-th node must be equal to the specified number of flows to be executed.…”

“…The article review [10] found that the number of publications related to truck scheduling and scheduling is much higher than the number of articles related to cargo delivery planning in general. The most prominent of them use the methods of modified mathematical programming [11], simulation modeling [12], genetic algorithms. However, publications that would apply the principle of continuity of material flow and would consider the process of goods delivery as discrete, and as a whole are still unknown.…”

Network Applications (NetApps) as a 5G booster for Transport & Logistics (T&L) Services: The VITAL-5G approach

“…We discuss these issues further in the context of a very specific example, such as T&L operations in the river/sea ports. In particular, Aroca et al and Oliskevych et al [4,5] show that a highly specialized personnel in T&L industry (e.g., vessels captains, pilots, equipment, or train operators) is idle between 15-50% of the time, being conditioned by the availability of their assigned equipment. As the operational activities such as loading/unloading, and cruising on auto-pilot, do not require any intervention, this means that personnel can be engaged more efficiently with the help of new network capabilities, thereby including them in the remote operation of equipment as well.…”
