Instances for secure container loading under multi-drop and axle weight constraints

The data set can be utilized for loading and packing of rectangular items with multiple customers or item groups as well as weight-related restrictions. Each file is designed as follows: - The first line has two entries which indicate the number of customers/groups and the number of items/pallets. - Each of the remaining lines provide the details of a rectangular item in five entries: item ID, customer/group ID, dimensions in centimeters (long-edge length and short-edge length) and weight in kilograms.

For example, the NII-P7C3M file below corresponds to an instance with 7 items from 3 customers. Items 0 and 1 belong to customer 1, items 2, 3, and 4 belong to customer 2 and items 5 and 6 belong to customer 3. 3 7 0 1 120 80 500 1 1 120 80 500 2 2 120 80 1500 3 2 120 80 1500 4 2 120 80 1500 5 3 120 100 2400 6 3 120 100 2400 The file IDs contain information about the number of items and customers as well as weight and dimension categories.
