Daily concrete orders from construction sites in Quebec, supplied by a concrete producer and processed into instances for the concrete delivery problem, with client and site information anonymised.
This entry has no fetchable recipe yet: Each instance is a MATLAB 5 file whose orders, the nodes with their quantities, mix codes and delivery times, are a MATLAB table of datetime and other class objects, which MATLAB stores in the file's undocumented MCOS subsystem data rather than as arrays; the only plain arrays are the travel time and distance matrices, so nothing at node level can be read without reverse engineering that serialisation.
