However the effects of congestion are eroding the significant progress that has been made in inventory management and warehouse control. Two types of changes appear to be happening simultaneously. First reductions in labor costs attributable to inwarehouse efficiencies are being absorbed by the costs of the over-the-road operations more equipment and drivers to deal with congestion and driver hours of service limitations . Second by re-introducing uncertainty in shipping and receiving attributable to the over-the-road and last mile portion of the supply chain system businesses are forced into looser scheduling setting lower delivery targets and adding additional inventory a reversal of recent trends in lowering inventory to allow for uncertainty in delivery times. Impaữed Cross-Docking Operations - Congestion impacts are particularly notable for cross-docking operations. Both the efficiency and feasibility of cross-docking operations are tied to the ability of originators to deliver inbound loads within a given window of time needed to reposition loads for outbound customers - typically very early in the morning. Late inbound delivery creates storage and loading problems. As the communications and inventory control infrastructure required to support cross-docking operations becomes more widespread and more critical to improving efficiency and lowering costs of transportation and logistics delivery reliability will become an even greater issue in the successful adoption of cross-docking in warehouse and logistics management. Insofar as this practice becomes more integrated into transportation and warehousing operations consideration will be given to locating new facilities in places where congestion is less of a factor in creating
