Tool Blocking in Flexible Manufacturing Systems
An analytical procedure to evaluate the performance of a Flexible Manufacturing System (FMS) with a separate tool transportation system is presented. Of particular interest is the tool blocking time, which is defined as the time a machine is idle because it has to wait for the required tools. In order to evaluate this time, both systems of the FMS, the parts transportation system and the tool transportation system, are modelled as two interacting closed queueing networks.
