A computer implemented method for determining a transport instruction for an automated vehicle which transports a pallet with goods in a pallet rack channel, wherein the pallet rack channel is a shelf in a pallet rack which accepts a plurality of pallets to be stored sequentially along one direction between a load end of the pallet rack channel and a far end of the pallet rack channel, wherein the automated vehicle is a vehicle which can automatically transport the pallet from the load end to a pallet position by driving in the pallet rack channel, wherein the pallet position is a position of the pallet along the one direction between the load end and the far end, and wherein the transport instruction is an instruction to the automated vehicle to transport the pallet to the pallet position, the method comprising: determining a pallet depth, wherein the pallet depth is a measure of a space that the pallet with goods will occupy along the one direction of the pallet rack channel when the pallet is stored in the pallet rack channel; determining a first pallet position, wherein the first pallet position is the pallet position furthest from the load end which is free to accept a pallet to be stored; determining a firebreak zone, wherein the firebreak zone is a region in the pallet rack channel and along the one direction of the pallet rack channel in which no pallet with goods is allowed to extend, the firebreak zone being wider than a spacing between pallet depths of consecutive pallets stored inbetween two firebreak zones; calculating a second pallet position from the determined pallet depth, the determined first pallet position and the determined firebreak zone, such that the second pallet position lies between the load end and the first pallet position and such that the pallet with the pallet depth does not extend into the firebreak zone when it is stored at the second pallet position; forming the transport instruction based on the second pallet position such that the automated vehicle can transport the pallet to the second pallet position; determining a pallet depth, wherein the pallet depth is a measure of a space that the pallet with goods will occupy along the one direction of the pallet rack channel when the pallet is stored in the pallet rack channel; determining a first pallet position, wherein the first pallet position is the pallet position furthest from the load end which is free to accept a pallet to be stored; determining a firebreak zone, wherein the firebreak zone is a region in the pallet rack channel and along the one direction of the pallet rack channel in which no pallet with goods is allowed to extend, the firebreak zone being wider than a spacing between pallet depths of consecutive pallets stored inbetween two firebreak zones; calculating a second pallet position from the determined pallet depth, the determined first pallet position and the determined firebreak zone, such that the second pallet position lies between the load end and the first pallet position and such that the pallet with the pallet depth does not extend into the firebreak zone when it is stored at the second pallet position; forming the transport instruction based on the second pallet position such that the automated vehicle can transport the pallet to the second pallet position;
