This is order instances for different order structures and different order numbers, also the fatigue parameters for different workers are given
some explanation on the files:
e.g. in orderset_new_1000 series file, 1000 represent order number. each row is order, each column is item type, and each cell is the item number in the order. First column is order id
e.g. orderset_new_60-12 series file, order number are fixed to be 800, 60 represent 60 item types, and 12 means each item number is less or equal to 12.
