|Abstract: ||The number and time of raw material’s arrival can be determined accurately by
calculating the number of raw material which should be ordered to the supplier. The first
step to find out the number of raw material which should be ordered by using Supply
Chain Management method is determines the period and doing demand forecasting.
Then, determines the lead time (L) which the formulation is L =
) ( n n xP L ∑ . The next,
determines starting inventory in each period (I) where It = It-1 – Dt-1 + L t
Q − , calculate
order up to target (R) where
R = D( L + 1) + SS. After that, order quantity (Q) can be found by formulating
Qt = Rt – It – Ot, where Ot (on order quantity) =
. All of the calculation must be
done alternately in each period and entered into supply chain table. The last step is
calculating procurement cost, i.e. ordering, purchasing, holding, and stockout cost.
The result revealed that the SCM method influences the smoothness of raw
material’s supply with 2 days lead time and 2.411 tons safety stock. The raw material
requirement can be determined, so the supplier can allocate the raw material which must
be supplied to the factory, so that lack or surplus of raw material was not happened.
Based on cost calculation, the SCM method can reduce ordering cost by Rp. 440,400.00
and stockout cost can be canceled, but increase the purchasing cost by Rp.
151,830,000.00, so that the total cost can be decreased by Rp. 485,618,400.00 per year.|
