Simulation Model Approach for Evaluating and Improving KPIS of Barge Shipment Operations in Coal Industry
Abstract
PT. XYZ has a new coal mine in Kalimantan Island. Therefore, a new track for shipping the coal is also made. The shipment is conducted with two cycles. The upper cycle is done by transhipping to the intermediate stockpile through the new track in Barito River, while then it continued by the lower cycle which goes to the mother vessel in high seas using a bigger barge before it is delivered to the customers. However, there are a lot of constraints existed in the new track, such as the tidal condition of the river which may affect the possibility of shipping, and the long queuing of unloading the barge in ISP which impacting a long cycle time. Therefore, the logistics department already has KPIs for the cycle time and the target of tonnage that should be delivered to the ISP. However, the recent KPIs are still made by manual calculation based on the historical data of shipment and the old data of sailable probabilities of Barito River, which are not fit with the current situation. The research is focussing on evaluating and improving the KPIs with the tool of simulation model using Flexsim Software to simulate the barge shipment operations. The results might be a recommendation for the logistics department for future logistics planning.
