| Abstract | Booster stations are fluid systems consisting of interconnected components such as pumps, pipes, valves and fittings. One of their main applications is to supply whole buildings or higher floors with drinking water if the supply pressure of the water company is not high enough to guarantee a continuous supply for all consumers. This means that a booster station must increase the pressure of supplied drinking water at a given time-variant flow rate. The consumer's demands must be matched at any time and the system operation is restricted by the general laws of fluid mechanics. A common approach to handle the corresponding optimization problem is to model it as a mixed integer linear program (MILP) and to solve this program using a standard MILP solver. This approach is not suitable for large problem instances with practical relevance as it is not possible to obtain good solutions in reasonable time. Hence, the main obstacle is the optimization speed. In this work, we present an approach to obtain good solutions in reasonable time even for large practical relevant instances. We do this by addressing the problem with heuristics from both the primal and dual side combined with the use of problem specific and technical knowledge. This approach is based on modeling the problem as a MILP as well as a mathematical graph and using both views simultaneously. |

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.
