SPT, which maximizes the number of jobs using the first tool, does well in packing jobs on to these tools. Therefore, after a small and predetermined number of ...

Tool management is also one of the key issues in FMS, which has attracted the attention of many researchers. The problem of switching tools in FMS has been ...
Thus, their tools need to be changed within a pre-determined time. Machines cannot process jobs during the known and constant tool change times [6] , [8].
