WebThe container relocation problem (CRP) is concerned with finding a sequence of moves of containers that minimizes the number of relocations needed to retrieve all containers, while respecting a given order of retrieval. However, the assumption of knowing the full retrieval order of containers is particularly unrealistic in real operations.

An exact approach for the Blocks Relocation Problem

WebContainer relocation problem (CRP) involves the retrieval of all containers from the container yard with a minimum number of relocations. The CRP is an NP-hard problem such that the large-scale instances cannot be solved to optimality by exact solution methods within a reasonable computational time. WebJun 15, 2015 · Abstract: The block relocation problem, which is also known as the container relocation problem, is an optimization problem to find an optimal sequence of operations for retrieving blocks (containers) from a container yard in a given order. The objective function to be minimized is the number of necessary relocations. c ou shift
