Abstract Nowadays in air cargo terminals one of the most important problems is the scheduling of freight handling employees. The build-up and break-down of the unit load devices (ULDs) are the most manpower-intensive operations at air cargo terminals. This particular area is critical for achieving cost reductions while maintaining customer service levels. Efficient management of manpower resources for cargo handling personnel can help terminals improve the manpower utilization and reduce operating costs accordingly. This Master Thesis aims at optimizing the operations of the Spirit Air Cargo Terminal at Kastrup airport in Copenhagen by fully utilizing the manpower resources for cargo handling. Based on the demands of incoming and outgoing cargo and on the handling capacities of the individual build and break workers as well as an effective demand leveling mechanism, an optimization model for personnel scheduling can be formulated. The solution of the optimization model can provide high (well above 90%) manpower utilization and 100% customer service levels (no delayed cargo). Therefore, the manpower cost at the terminal can be reduced greatly while maintaining a high customer service levels. How to perform this theoretical manpower utilization and customer service levels is an important, interesting and challenging subject in practice. The optimization model differs from reality mainly because the aggregate demand for the outgoing and incoming air cargo is in kilograms while in practice the outgoing cargo must be consolidated into individual ULDs by build workers and the incoming cargo must be unloaded from ULDs by break workers at the workstations. Therefore the ULD release mechanismfrom the storage area into the workstations can affect the practical manpower utilization greatly. This thesis integrates the optimization model for manpower scheduling and the simulation model of the air cargo operations to find the best ULD release mechanism in order to efficiently utilize manpower resources in practice while maintaining the customer service levels. Keywords: air cargo terminal, personnel shift scheduling, simulation model, optimization model, manpower utilization.
