This question illustrates the effect of different levels of
WIP in a serial production system using CONWIP production control.
Use the Penny Fab simulation (Penny Fab_CW.mox) in the Examples/Models
and Methods folder. Simulate the system with different levels
of WIP with the lowest value set at 1. In each case make 10
runs of 1000 minutes each. Make a plot of WIP versus throughput
rate. Justify Littles law with the data. Comment on the
effects of WIP level on the throughput and cycle time.
