WebIn this paper, we address the pre-marshalling problem by developing and testing integer linear programming models. Two alternative families of models are proposed, as well as an iterative solution procedure that does not depend on a difficult to obtain upper bound. WebFeb 10, 2024 · The blocks relocation problem requires to find the relocation sequence for each pickup operation so that the number of future relocation moves for accessing blocks of interest is minimized. The application is based on a DP recursion that identifies all possible relocation sequences that can be generated following the known picking list.

An exact algorithm for the unrestricted container relocation problem ...
WebJul 1, 2024 · The purpose of this study is to propose an exact algorithm for the unrestricted block relocation problem with distinct priorities. In this problem, a storage area is considered where blocks of the same size are stacked vertically in tiers. Because we can access only topmost blocks, relocations of blocks are required when other blocks are … WebDownloadable! This study aims at achieving the optimized stowage plan based on the containers’ distribution in the yard and space structure of the ship by integrating the containership stowage problem with the block relocation and loading problem. The containership’s physical structure contributes to a variety of stowage plans, and the … WebMay 16, 2012 · In this paper, we describe and analyze the blocks relocation problem (BRP), in which one is given a block retrieval sequence and is concerned with finding a … heather simonson
