Penjadwalan Batch Dinamis Flow Shop Untuk Meminimasi Rata-Rata Keterlambatan Penyelesaian Order (Mean Tardiness) dan Jumlah Scrap Tuang di CV. Kembar Jaya
Abstract: CV. Kembar Jaya is a
metal casting manufacturing company which applies Make to Order (MTO) system.
It,s characteristic of scheduling is dynamic batch on flow shop production
system. This scheduling method has risen the tardiness of order completion and
high level of pouring scrap. To solve this problem, a rescheduling procedure
which able to increase the system’s performance is needed. To increase the
system performance, a development of batch dynamic scheduling algorithm has
been done to minimize the mean tardiness and total pouring scrap. The algorithm
consists of setting molding area initialization and five sub algorithms. Sub
algorithm of sorting order and determinating batch size will sort and breakdown
the order into batches. Sub algorithm of molding area repairing will determine
molding area allocation for batches. To prevent the drop temperature, sub
algorithm of determination pouring time will identify the pouring temperature
for batches. Sub algorithm of batch scheduling will schedule batch to work
station. Then sub algorithm of rescheduling will accommodate the dynamic
environment when order was inserted. Mean tardiness from the scheduling
algorithm application is 7.39 hours or minimize mean tardiness until 65.72 %,
from the current scheduling algorithm. Application of the scheduling algorithm
can reduce total pouring scrap into 0 kg or 100 %.
