Blocks relocation problem

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.
