- The following instances are originally presented in the working paper "High-density storage with mobile racks: Picker routing and product location" written by Foroughi, Amir, Boysen, Nils, Emde, Simon, and Schneider, Michael. The data corresponds to 360 instances each in its own file. Each file is structured as follows: The first line contains: the number of racks, the number of locations in each rack. (Please note that the number of aisles in each instance is the number of racks minus one) Then there follows a line with the name of each SKU. Then a line with waiting time in seconds (the time it takes for an aisle to be opened) Then a line with the distances from the aisle cross to the depot for each aisle. Then a line with the driving time between two consecutive aisles. It means how long it takes for the SRV to travel from one cross aisle to the next cross aisle. Then the lines for the location of SKUs in each rack, where each line is associated with one rack. In each pair of numbers, the first number is the name of SKU and the second number is the position of that SKU in the rack. For example, in the first rack, 3 1 5 3 2 4 means SKU 3 is in location 1, SKU 5 is in location 3, and SKU 2 is in location 4. All numbers in the same line are separated by spaces.
