[15:55, 1/15/2018] Mas Ridwan: Indonesia merupakan Negara berkembang yang sedang mengalami pertumbuhan hal ini menyebabkan peningkatan GDP yang signifikan. Target produktivitas Indonesia harus mencapai 60% untuk dapat mempertahankan nilai barang dan jasa sebesar 6% – 7%. Ketidakmerataan pertumbuhan GDP di Indonesia khususnya terjadi pada kawasan di luar pulau Jawa dikarenakan akses yang sulit…
Efficient handling of containers at a terminal can reduce the overall vessel sojourn times and minimise operational costs. The internal transport of containers in these terminals is performed by vehicles that share a common guide path. The throughput capacity of a terminal may increase by increasing the number of vehicles; however, simultaneously congestion may reduce the effective vehicle spee…
One of great challenges in seaport management is how to handle containers under reshuffling, called reshuffles. Repositioning reshuffles in a bay (internal reshuffling) can improve the efficiency of quay cranes and help ports to reduce ship turn-around time. This paper studies the quay crane double-cycling problem with internal-reshuffling operations, and presents a fast solution algorith…
Over the recent years, the use of containers for intercontinental maritime transport has dramatically increased. Figure 1 exhibits the growth of world container turnover. Starting with 50 million twenty feet equivalent unit (TEU) in 1985, world container turnover has reached more than 350 million TEU in 2004. A further continuous increase is expected in the upcoming years, especially between As…
The yard truck scheduling and the storage allocation are two important decision problems affecting the efficiency of container terminal operations. This paper proposes a novel approach that integrates these two problems into a whole. The objective is to minimize the weighted sum of total delay of requests and the total travel time of yard trucks. Due to the intractability of the proposed proble…
Most of the operational problems in container terminals are strongly interconnected. In this paper, we study the integrated Berth Allocation and Quay Crane Assignment Problem in seaport container terminals. We will extend the current state-of-the-art by proposing novel set partitioning models. To improve the performance of the set partitioning formulations, a number of variable reduction techni…
