Problem instances for scheduling personnel for the build-up of unit load devices at an air cargo terminal with limited space

We randomly generated problem instances for the problem of scheduling the build-up of unit load devices at an air cargo terminal under space and personnel constraints (ULDSP in the following) which are used in the working paper "Emde, S., Abedinnia, H., Lange, A., and Glock, C. (2018): Scheduling personnel for the build-up of unit load devices at an air cargo terminal with limited space. Working paper TU Darmstadt". In total there are 60 problem instances which are divided in three datasets (small, medium, large) each of which contains 20 problem instances.
