| Abstract | In this paper, we study a two-stage capacitated facility location problem with choice of facility size. Given a set of potential sites for plants and a set of potential sites for depots, each of the plants and the depots has several possible sizes, and a set a customers with demands, the aim of the problem is to determine the locations of the plants and the depots as well as their sizes, the product flows from the opened plants, via the opened depots to the customers under the single-sourcing constraints, so that all of the customers' demands are satisfied with the minimum sum of the fixed opening costs of the facilities, the producing costs at the plants, the handling costs at the depots, the transportation costs from the plants to the depots and the customer-depot assignment costs. A mixed integer programming model for the problem is formulated and a LaGrange an relaxation approach is proposed to achieve a lower bound and an upper bound of the problem. The performance of the LaGrange an relaxation approach is evaluated on 200 randomly generated instances. The computational results demonstrate that the LaGrange an relaxation approach is effective with the average gaps around 1.30%. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
