| Abstract | The combined transport appears as a promising alternative to road transportation for containers allocation. It possesses a strong potential market, conditioned by the development of its quality of service (improvement of the system, terminals, and service performances in terminals). Multimodal transport of containers can be an alternative to the road transportation but it requires to be competitive in term of quality of service and price. We address specifically the problem of optimizing container loading on trains in rail-rail trans-shipment shunting yard to minimize the frequency of transfers within yards. In such yards, trains succeed one another upon arrival and departure. Based on their final destination, containers are unloaded from their initial original train by automated handling systems, to be reloaded on a departing train at a defined place. It is discussed how to determine the initial loading place of containers on arriving trains and their reloading place on departing trains. Our primary goal is to minimize the frequency of transfers within a particular yard, the secondary goal is to complete the use of handling equipments. The problem is characterized as problem of minimum cost multicommodity network flow with binary variables, which are often difficult to solve to optimality The problem statement and its mathematical formulation are developed. They can be reformulated, thanks to exact penalty techniques in DC Programming, as a polyhedral DC Program and globally solved by a combination of the local algorithm DCA and B&B. Numerical simulations that show the efficiency of DCA and the combined DCA - Branch and Bound algorithm are reported. |

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.
