Abstract

Loading containers into a vessel can be delayed because of inefficient processes in the container yard. These container yard inefficient processes can be caused by inappropriate stacking position and inefficient crane operation. Inappropriate containers stacking positions may need some preparatory jobs of rearranging containers ahead of loading time to reduce delays in the process. The method will allow preparatory jobs to be scheduled together with main jobs to optimize use of the idle time of ASCs. This research aims to find a better scheduling strategy of twin ASCs as well as improving land utilization in a vertical-layout container yard to minimize delays in containers loading process. The uncertainty of truck arrival is accomodated by implementing iterative rescheduling in look-ahead planning horizon. The algorithm finds the optimal position of the container in the yard by implementing scoring function for each available slot. Finally, some numerical experiments are conducted to prove the performance of the algorithm.

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.
