| Abstract | Major issues of urban drainage are to cope with flooding caused by torrential downpour and water pollution caused by washing load from non-point sources. To reduce the damage of flooding, large-scale trunk sewer and pumping stations are constructed in large Japanese cities. To reduce the damage due to water pollution, these sewerage systems should have additional functions of storage and treatment of the washing load. In such a case, pump operation has key roles for reduction of damages. To obtain the optimal policy of such operation, many types of optimization method have been proposed. Stochastic dynamic programming (SDP) is an excellent method of obtaining the optimal operation policy. Most SDP models assume the state variables such as storage volumes are perfectly observable. However, for actual operation, construction of the observation system to observe state variables perfectly is difficult. Therefore, these facilities should be controlled under imperfect information. The research in this field is not so advanced though such problems are thought to be important in a city, which has many such facilities. The paper shows formulation of such optimal control under imperfect (partially observed) information by using a SDP model. |

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.
