Abstract:
In a batch production series consisting of several
process stages for discrete products, the determination of the transfer
batch size greatly affects the batch waiting time. For production using
a Computer Numerical Control (CNC)-machining center, several
process stages can be carried out on one machine with quick setup.
The use of a single machine for all stages of the process certainly does
not require transfer to the next machine. Thus, there are no material
handling costs. However, the use of a single machine will result in
longer batch waiting times as the production batch size increases. An
increase in the batch waiting time will result in an increase in work-inprocess
(WIP) inventory cost. This research was conducted to reduce
the total variable cost consisting of WIP inventory cost and material
handling cost.
