This paper presents a hybrid metaheuristic for solving the static dial-a-ride problem with heterogeneous vehicles and fixed costs. The hybridization combines a reactive greedy randomized adaptive search, used as outer scheme, with a tabu search heuristic in the local search phase. The algorithm...

Four different modes for transporting wood in the first three stages of the wood supply chain are introduced and compared for real-life-based test cases under various scenarios. They include log-trucks and (foldable) containers. Freight forwarders are employed by sawmills to perform the...
