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...

We focus on the D-optimal design of screening experiments involving main-effects regression models, especially with large numbers of factors and observations. We propose a new selection strategy for the coordinate-exchange algorithm based on an orthogonality measure of the design. Computational...

The Vehicle Routing Problem with Backhauls (VRPB) is an extension of the VRP that deals with two types of customers: the consumers (linehaul) that request goods from the depot and the suppliers (backhaul) that send goods to the depot. In this paper, we propose a simple yet e ective iterated...
