Analisis Pengendalian Persediaan Bahan Baku Packing Menggunakan Metode Joint Replenishment Problem

PT Out Of Asia is an exporting company that produces handicraft products. All products in the company are semi-finished products from suppliers who performed the finishing and packing stage. The production process system is done by the company varies according to the demand of the consumer, so the raw material of packing needed also vary.
