Outline of Final Research Achievements

The block (container) relocation problem and the block (container) pre-marshalling problem were studied. The former problem is to minimize the total number of relocations necessary for retrieving blocks piled up in tiers one by one according to a specified order. The latter is to minimize the total number of relocations necessary for re-ordering blocks in preparation for future retrieval. In this study efficient exact algorithms were proposed for the two problems. An exact algorithm for the block relocation problem to minimize not the total number of relocations but the total crane operation time was also proposed. Extensive numerical experiments showed that the proposed algorithms are much faster than existing algorithms.
