Performance evaluation of an FMS (Mean-Value Analysis)
Mean-Value-Analysis is applied to compute the exact performance measures of a Flexible Manufacturing System with universal pallets, that is modeled as a product-form closed-queueing network.
The last station (M) is the transportation station (central server). Its relative arrival frequency is always 1.0 (non-editable). Be sure that the relative arrival frequencies of the remaining stations (1 to M-1) sum up to 1.
|m||index of stations|
|e||index of the bottleneck station|
|b(m)||mean processing time of a typical workpiece at station m|
|p(m)||relative arrival frequency of a pallet at station m|
|S(m)||number of servers at station m (machines, vehicles, etc.)|
|N||number of pallets circulating in the system|
