The cell is composed of seven machines:

• a loading/unloading unit (M1),
• three assembly workstations (M2, M3 and M4),
• an automatic inspection unit (M5),
• a recovery unit (M6), which is the only manual workstation in the cell, and
• an optional workstation (M7), only usedfor agiven dynamic scenario.

Machines are responsible for the completion of manufacturing operations to do the jobs. Some machines are able to complete the same manufacturing operation (flexibility), while some manufacturing operations can be completed on a single machine.

Supply storage area

Each assembly workstation has also its own supply storage area, which is used for supply purpose in components. Since, in this benchmark, this supply is assumed infinite, this supply storage area is not used in the scenarios.

Manufacturing operation processing times

The following table provides the manufacturing operations feasible on the different machines by providing the corresponding manufacturing operation processing times. Otherwise, these machines cannot carry out the manufacturing operations.
