Abstract | Recently, the increasing focus on environmental protection has led to significant change in logistics processes. Reverse logistics begin to be paid more attention by researchers. In reverse logistics, the customers who have both a pick-up and a delivery demand are serviced with a single stop. In this paper, the reverse logistics problem of simultaneously distributing commodities and collecting re-usable empty packages with a single depot and a fleet of uniform vehicles is studied. Commodities to be distributed are loaded at the depot and delivered to the customers. The empty packages are collected from the customers and transported back to the depot. The objective is to minimize the total distance traveled by all vehicles while servicing all customers. After a simple description of the problem, the vehicle routing problems in reverse logistics is investigated, a mathematic model of the problem is built. Then, a genetic algorithm to the problem is suggested. In this algorithm, the ranking replacement method is used, and the population is partitioned into four subsets with respect to the fitness and unfitness of the offspring. Finally, the proposed genetic algorithm is successfully applied to some problems, and the superiority of the genetic algorithm is proved through the comparison of the genetic algorithms with a heuristic algorithm. |

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.
