Model Joint Economic Lot Size (JELS) pada Kasus Pemanufaktur-Pembeli dengan Permintaan Probabilistik dan Lead Time Variabel
Abstract: We consider a
two-layer supply chain model consisting of a vendor and a buyer. The buyer
observes a probabilistic demand and orders lots from the vendor. We relax the
assumption of deterministic lead time and assume that it is varying linearly
with the delivery lot size. The vendor manufactures the requested product in
production batchs. Each produced batch is shipped to the buyer in lots. We
consider a situation where there are multiple deliveries for one order and the
vendor produces in a multiple integer of delivery quantity and hence, an order
can be split into a number of production runs. A solution procedure is suggested
for solving the proposed model and numerical examples are used to illustrate
the benefit of integration. Numerical results show that the integrated
inventory model will always result in savings in the total joint cost, buyer
cost and vendor cost.
