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. WebThe container relocation problem, also known as the block (s) relocation problem, is one of the most studied optimization problems in container terminals. The problem aims at minimizing the total number of relocations for retrieving containers from a storage yard according to a specific order. WebThe container relocation problem is one of the most relevant problems in the logistics of containers. It consists in ﬁnding the minimum number of moves that are needed to retrieve all the containers located in a bay, according to a given retrieval order. Unfortunately, such an order may be subject to uncertainty. northeast vet clinic el paso texas
