Abstract
As an archipelago country, sea transportation plays a vital role in Indonesia. This condition challenges Indonesia’s companies which offer sea transportation service to fulfill customer needs yet still maintain profit maximization. Shipping lines companies are examples of sea transportation service companies. PT Salam Pacific Indonesia Lines (SPIL) is one of the Indonesian private shipping lines company which operates at least 25 ports with 3 homebases across Indonesia. In PT SPIL, the sub-division of Container Inventory Control (CIC) has the responsibility to control and manage all containers, including empty container inventory level, in ports and homebases. In other words, CIC needs to balance the empty container inventory level among ports and homebases in order to minimize the possibility of empty container overstock and shortage. The current empty container inventory control system in PT SPIL is centralized in homebases, so there is no exact calculation for determining inventory parameter in ports. This research is focused on improving the performance of the current inventory control system in PT SPIL by proposing a discrete event simulation model of empty container Reorder Point (ROP), in which uncertain empty container demand and lead time, empty container inventory level and reorder costs, as well as initial ROP using exact formula are used as input variables. Using Arena simulation software, initial ROP in 5 ports (Banjarmasin, Jayapura, Samarinda, Timika, and Ternate) and 1 homebase (Surabaya) is evaluated in 10 scenarios. Those scenarios are justified using 2 response variables, average inventory level and total empty container reorder costs. It is expected that recommended ROP will affect in low inventory level as well as total reorder costs. By considering those factors, after a year simulation, the recommended ROP scenario for Homebase Surabaya, Port Banjarmasin, Port Jayapura, Port Samarinda, Port Timika, and Port Ternate are consecutively 500 units, 133 units, 63 units, 94 units, 8 units, and 7 units. Compared to the initial scenario, the average inventory level reduction ranges from 22.66% to 89.39% with the biggest empty container reorder costs reduction of 100%.
