Space-sharing Strategy for Building Dynamic Container Yard Storage Considering Uncertainty on Number of Incoming Containers

Abstract

The implementation of AEC (Asian Economic Community) leads to demand increase at ports in Indonesia. This increasing demand is followed by operational efficiency at the port as well. In fact, ports in Indonesia have an average dwell time for 5 days. One of the causes of this long dwell time is container transfer inefficiencies during loading process. In this research, we will focus in yard management and increasing land utilization. To increase the land utilization, we develop the space-sharing concept to reduce the initial space needed for a given workload. Since the ships arrivals are also varying, this concept will be possible. We develop the concept by adding uncertainty on number of incoming containers at operational level as the determining factor in planning a shared yard area. We propose a simulation approach to evaluate strategies in making yard template.

Dynamic Yard Template Design to Improve Utilization and Operation Efficiency on Vertical Layout-Container Yards Considering Uncertainty of Truck Arrival

“…Because of this problem, yard operators usually open less than 100% of the booked spaced on early booking day. At first, 30% of the booked spaced are opened and the percentage of opened booked space will be added if the incoming containers increase [4]. By this strategy, the land efficiency will increase, but some containers for the same vessel may be placed far from others.…”

“…Dwelling time is defined as the average time of container being in the port. The causes of this long dwell time are the complicated bureaucracies, the scarcity of land for container yard and a container transfer inefficiency during loading process [4].…”

“…Previously, Nurminarsih et al [4] has been developed a sharing-area framework for vertical layout-container yard under uncertainty of the arrival of containers which is adopting the method developed by Jiang et al [7] and Zhen [5]. The research is developed based on real situation in one of port in East Java, Indonesia, which implement vertical layout-container yard.…”

“…This probability is based on historical data of container arrival. Nurminarsih et al [4] only introduced the framework and method for implementing the space-sharing concept without considering the movement of ASC. This research aims to develop the previous research of Nurminarsih et al [4] by taking into account the scheduling of ASCs.…”

Model for scheduling ASCs is adopted from Choe et al [11] while adding the consideration of space utilization as the outcome of sharing-area concept.…”
