Here we attach the instances that are refered to in the paper "Satisfying flexible due dates in fuzzy job shop by means of hybrid evolutionary algorithms".

File format:

=======================================================

The instances are formatted as follows:

- The first two lines indicates the number of jobs

- The next two lines indicates the number of resources/machines

- The following is the machine requierement matrix

- The number in row "r" and column "c" is the machine required by the "c"-th task of job "r".

- The last matrix cotains the task durations

- The TFN in row "r" and column "c" is the duration of the "c"-th task of job "r".

- Last two rows contain the flexible due-dates foe each job
