The flexible job shop scheduling problem considering the on-site machining fixtures (FJSP-F) benchmark test suite is provided in this file [1]. The LLG-F includes 20 instances (LLG-F1 to LLG-F20) with various scales ranging from three jobs, four machines, and two fixtures to 20 jobs, ten machines, and 12 fixtures. ------------------------------------------------------ The meaning of the main variables:1. dt: The delivery time of each job2. Jm: The eligible machine set of each operation.3. JmNumber: The total number of the machines4. Jf: The eligible fixture set of each operation.5. pjob: The priority of each job.6. rt: The release time of each job.7. T: The processing time of each operation.8. fixnumbegin: The number of Type I fixtures of each fixture (The number of each fixture in inventory)9. fixnumend: The sum of the number of Type I fixtures and Type II fixtures of each fixture (The number of each fixture after the production)10. fixtype1: Categories of Type I fixtures11. fixtype2: Categories of Type II fixtures12. fixtype1seq: Sequences of Type I fixtures13. fixtypewseq: Sequences of Type I fixtures [1] J.
