We present a hybrid approach to solve the log-truck scheduling problem (LTSP), which combines routing and scheduling of forest vehicles and includes aspects such as multiple products and inventory management. The LTSP is closely related to some routing problems encountered in other industries, in particular, so called “pick-up and delivery problems”. In general, the LTSP are more complex than classical PDP, since in the LTSP we must synchronise trucks and log-loaders to avoid as much as possible waiting times.
