Data for order picking in warehouses with decoupling of picker and cart

For most current algorithms, the difficulty of finding an optimal solution increases as the number of cross aisles increases, making order picking with decoupling more difficult in a multi-block layout. To verify the performance of the algorithm, we utilize the instances in Theys et al. (2007) to create new instances for SPRDP.

We organize instances and detailed solutions into benchmarks which can be then made publicly available as validation tools for future research methods.
