| Abstract | This paper introduces and solves a new practical variant of integrated routing and loading problem called the capacitated vehicle routing problem minimizing fuel consumption under three-dimensional loading constraints (3L-FCVRP). This problem requires to design routes for a fleet of homogeneous vehicles located at the central depot to serve all customers, whose demand are formed by a set of three-dimensional, rectangular, weighted items. Different from the well-studied problem: capacitated vehicle routing problem with 3D loading constraints (3L-CVRP) in literature, the objective of 3L-FCVRP is to minimize the total fuel consumption instead of travel distance. The fuel consumption rate is assumed to be proportionate to the total weight of the vehicle. A route is feasible only if a feasible loading plan to load the demanded items into the vehicle exists and the loading plan must satisfy a set of practical constraints. To solve this problem, the evolutionary local search (ELS) framework incorporating with recombination method is employed to explore the solution space and an open space based heuristic is used to examine the feasibility of solutions. To verify the effectiveness of our approach, we first test ELS on the instances of 3L-CVRP, which can be seen as a special case of 3L-FCVRP. The results demonstrate that ELS outperforms all existing approaches on average and improves the best known solutions for most of the instances. Then, we generated data for 3L-FCVRP and reported the detailed results of ELS for future comparisons. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
