We study a new network design model combining ring and tree structures under capacity constraints. The solution topology of this capacitated ring tree problem (CRTP) is based on ring trees which are the union of trees and 1-trees. The objective is the minimization of edge costs but could also...

Horizontal logistic collaboration leads to large prots when the right coalition is formed. Most of the previous research however explains the profit differences using market conditions on coalitional level. We show that the level of profit is highly dependent on finding a correct combination of...

Distribution companies that serve a very large number of customers, courier companies for example, often partition the geographical region served by a depot into zones. Each zone is assigned to a single vehicle and each vehicle serves a single zone. An alternative approach is to partition the...

This paper proposes a variant of the well-known capacitated vehicle routing problem that models the problem of routing vehicles in the cash-in-transit industry by introducing a risk constraint. In this problem, which is called the risk-constrained cash-in-transit vehicle routing problem...

This paper proposes a variant of the Vehicle Routing Problem in which a particular kind of risk constraint has been introduced to model the problem of routing vehicles in the cash-in-transit industry and a hard time window constraint, with no waiting times, delimits the customer's visit within a...

In this paper, we propose a new metaheuristic to solve the Risk constrained Cash-in-Transit Vehicle Routing Problem (rctvrp). The rctvrp is a variant of the well-known capacitated vehicle routing problem and models the problem of routing vehicles in the cash-in-transit sector. In the rctvrp, the...

Assigning and scheduling vehicle routes in a stochastic time-dependent environment is a crucial management problem. The assumption that in a real-life environment everything goes according to an a priori determined static schedule is unrealistic. Our methodology builds on earlier work in which...
