Pengembangan Model Variable Review Period dengan Mempertimbangkan Order Crossover
Abstract: In this paper, we
propose a variable review period model using dynamic programming for order
crossover problem. The
proposed model is
compared to an
existing variable review period model and classical review
period in terms of minimum inventory cost. The simulation is applied with
six scenarios and
sensitivity analysis is
also done. The
results show a
variable review period model performs smaller inventory cost for small
variation of lead-time compared to classical
review period model.
On the other
hand, classical periodic
review model is
sensitive with the changes in the variation of demand distribution and
service level. The proposed model gives the better solution compared to
variable review period model for the six scenarios with the inventory cost
saving as 11-42%. The sensitivity analysis for a variable review period model
and a proposed model
are applied and
compared. From sensitivity
analysis, it can
be concluded variable review
period with dynamic
programming gives the
best solution in
terms of the changes of holding cost and ordering
cost. It is also shown the smaller holding cost, the smaller percentage of inventory
cost savings (between variable review model and the proposed model).
