An input corresponding to a time window is received in an integrated container management system. For containers of a specific container type, a network flow solver implementing a multi-commodity network flow problem is executed based on the input. A graph is generated with nodes representing depot locations, mode of transport locations and customer locations. Arcs connecting nodes, and representing operations and costs associated with the nodes are generated. Pick-up arcs are generated between the depot locations and customer locations. Return arcs are generated between the customer locations and the depot locations. Street turn arcs are generated among customer locations. Unload load arcs are generated between the mode of transport locations and the depot locations. Output tables are generated with values representing functionalities associated with container repositioning, container pick-up and return, and container street turn. Container repositioning, container pick-up and return, and container street turn are optimized based on the values in the output table.
