| Abstract | Achieving high reliability of military platforms is critical for reducing operating costs and increasing operational availability and combat readiness. This paper describes results of a comparative analysis of two approaches to improving platform reliability. The first is based on platform inspections (performed at specific time intervals) and replacement of parts whose remaining life is found to be limited. By selecting appropriate inspection time intervals and fraction of remaining life left, various levels of platform reliability are achieved. The second approach utilizes prognostics capability, which provides estimates of remaining useful life based on platform's health state and the upcoming mission duration. In the analysis, the US Army Abrams M1A1 tank reliability data are utilized. Two operational regimes are considered. A steady-state situation develops after the tanks have been operating sufficiently long, and the average operational availability is not a strong function of time. In contrast, pulse reliability is achieved during a mission of limited duration (pulse). Such situations arise, for example, when tanks are selected for a specific mission that is limited in time, but during which repair or replacement of parts is not possible and high platform reliability is required. The presented results can be used for evaluating the benefits of prognostics approach, determining intelligent maintenance procedures, and developing effective strategies for achieving improved operational readiness and required pulse reliability |

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.
