Model Penjadwalan Pengiriman Pasokan pada Strategi Multi-Supplier dengan Variasi Harga dan Lead Time untuk Permintaan Stokastik
Abstract: Multi-supplier is
one of the strategies to minimize holding cost and average stock-out cost as
long as to stabilize the supply of raw materials. The common problems that the
firms may face when applying the multi-supplier strategy are determining the
right schedule and quantity ordered for each supplier. Complexity of the
problem increases with the facts that each supplier may have different
parameters, demand is uncertain, and the firms’ constraints. Thus, this research is
done to answer
two main objectives:
(1) to determine
the optimum safety
time (minimum raw material inventory) to prevent the stockout due to the
demand uncertainty and (2) to determine
the right schedule
and quantity ordered
for each supplier
considering the different
suppliers parameters: price, lead time, and supply capacity. The problem is
modeled in Mixed Integer Linear Programming with total minimum inventory cost
as the objective. With the aim of
testing the model,
a case of
multinational company that
apply the multi-supplier strategy is used.
