The operation of container handling vehicles and remotely operated specialized container handling vehicles are controlled by a method such that total elapsed time or waiting time cost for transferring specified storage containers between them is minimal or optimal. The specialized container handling vehicles are operating at a level below an automated storage and retrieval system having a framework structure defining a storage grid for storing storage containers in grid cells. The storage containers are stored and retrieved by container handling vehicles running on top of the storage grid. At least one operational controller, which is in communication with a first type of controller in each container handling vehicle and a second type of controller in each specialized container handling vehicle, performs the followings steps: when a specified storage container is to be transferred from a storage column and its corresponding grid cell to a specialized container handling vehicle: assigning and instructing a container handling vehicle to pick up the storage container from the grid cell and lower it to a selected port, located at the lower end of an identified free delivery column by transmitting instructions to the first type of controller of the assigned container handling vehicle, where the port selected is included as a variable in a weighting function together with time and waiting cost to derive a trade-off of the container handling vehicle and the specialized container handling vehicle having the best matching travel time to the port; moving the container handling vehicle to the grid cell, picking up the storage container and transporting it to a grid cell of the delivery column where the port is; transmitting a signal to the specialized container handling vehicles comprising information of the selected port at a first location and when the storage container will be available at the port; based on responses from the specialized container handling vehicles, assigning and instructing a specialized container handling vehicle to retrieve the specified storage container at the selected port; moving the assigned specialized container handling vehicle to the selected port at the first location, picking up the storage container and bringing it to a second location; and/or, when a specified storage container is to be transferred to a grid cell, for storage in its corresponding storage column, by a specialized container handling vehicle: determining which port at a first location that is to be used, where the port selected is included as a variable in a weighting function together with time and waiting cost to derive a trade-off of the container handling vehicle
