This research seeks to propose innovative routing and scheduling strategies to help city couriers reduce operating costs and enhance service level. The strategies are realized by constructing a new type of routing and scheduling problem. The problem directly takes into account the inherent...

In this paper, an approach based on Ant Colony Optimisation (ACO) is described for one-sided time constraint Vehicle Routing Problem (VRP), where the delivery of products from the depot to distribution centres has to take place within the maximum permissible time. The problem is described with...

In this paper, the value of correctly addressing uncertainty and risk in operational planning is studied in the context of the Vehicle Routing Problem with Stochastic Demands (VRPSD). The main issues analysed in this paper concern (1) the evaluation of different risk attitudes in planning...
