Abstract: A method of operating a laboratory sample distribution system is presented. The system comprises container carriers, a transport plane, and drive elements. The container carriers carry sample containers. The transport plane supports the container carriers. The drive elements move the container carriers on the transport plane. The method comprises planning a movement path for a container carrier from a start to a goal on the transport plane modelled by nodes. The nodes are free for one time-window or reserved for one-time window. The planning comprises analyzing the reachability out of a free time-window of one node to free time-windows of a next node and an over-next node such that planned movement of the container carrier is nonstop. The method comprises reserving the planned movement path comprising a sequence of time-windows of nodes and moving the container carrier along the reserved movement path on the transport plane by a drive element.
