Abstract
South Korea, by NewsRx correspondents, research stated, “In autonomous unloading systems, one of the major challenges is planning the unloading sequence in cluttered logistics container environments.” Financial supporters for this research include Ministry of Trade, Industry And Energy; Ministry of Science, Ict And Future Planning; Korea Ministry of Science And Ict. Our news correspondents obtained a quote from the research from Sungkyunkwan University: “Proper unloading sequence planning is crucial to avoid damage to the packages caused by collision and collapse. At the same time, the planned sequence has to minimize the effort during the unloading process, such as energy consumption, time taken, and distance moved, to enhance efficiency. This paper presents a sequence planning method based on the A-star search algorithm applied to unloading randomly stacked unidentical boxes from logistics containers. To represent the general overlap relationships of boxes in a cluttered environment, we utilize an adjacency matrix structure and involve it in the state of the unloading sequence planning. Moreover, by adopting the A-star search algorithm, the method can minimize the cost of system movement for an efficient unloading sequence. As a result, our method can determine the unloading sequence while considering the relationships between packages.”
