A hybrid adaptive large neighborhood search algorithm for the large-scale heterogeneous container loading problem.

• Investigated a large-scale heterogeneous container loading problem. • Considered weight limits and suspension constraints in this problem. • Integrated ALNS and heuristic packing algorithm for the presented problem. • Performed experiments on real-world instances. • Verified the superiority of HALNS by comparing with existing methods. This paper aims to solve the large-scale heterogeneous container loading problem (HCLP), which is an extensive form of the multiple container loading problem, in a limited time. The target is to choose a set of containers of different sizes to accommodate all products and minimize the wasted space rate. Although the heterogeneous container selection problem is a general problem in the logistics industry, few related studies have been conducted. This study also considers some practical constraints, such as weight limits and suspension constraints. A hybrid adaptive large neighborhood search (HALNS) algorithm, which includes a set of original destroy-repair operators, especially for heterogeneous container selection problems, and integrates a heuristic packing algorithm, is proposed to solve the problem in an acceptable time. To verify the efficiency of the proposed algorithm, computational experiments on real-world instances from a multinational logistics company are performed, and the results are compared with those of other existing algorithms. The results indicate that the proposed algorithm outperforms other algorithms for the HCLP. [ABSTRACT FROM AUTHOR]
