Work In Process Control for a High Product Mix Manufacturing System

The results obtained show that the CONWIP's regulation of total system WIP reduces throughput time and facilitates the application of sequencing rules in selecting the next product for processing. In real life, this might reduce the time needed by personnel to decide and identify the next product for processing. On the other hand, the Push control delivers a higher throughput rate, but can also lead to the proliferation of WIP which in turn increases the mean and variation of the throughput time. However, the application of the WIP control approach to sequence production under the Push control is able to avoid this negative outcome of the Push control.
