Abstract | Regular preventive maintenance scheduling (PMS) of generating units is required in order to prolong their life expectancy so as to ensure safe operating conditions, and most importantly to reduce the risk of unplanned outages due to failures. The decision making of PMS is related to the measures of economic dispatch and other planning activities that necessitate an exact mathematical PMS model. Traditionally, generator PMS problem is based on levelling the spinning reserve. However, in practical, levelling the reserve is not alone good enough. Including a probabilistic model along with the deterministic model is a welcome perspective. In this study, a new multi-objective model combining deterministic/probabilistic models is proposed. Furthermore, the generating unit failures have been incorporated in PMS to realise their impacts on reliability objectives. These aspects will increase further the complexity of the solution procedure. The advantages of modern bio-inspired algorithm, namely ant lion optimiser (ALO) attracts to use it as a main optimisation tool. The fuzzy decision mechanism is incorporated in the ALO to extract the best compromise solution in the multi-objective solution space. The standard test systems are used for implementation. Numerical simulation results indicate that the intended method has the capability of obtaining best compromised solution. |

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.
