| Abstract | This paper investigates the preventive age replacement policy for a system subject to random failures. According to such a policy the system is replaced by a new one, either at failure or at given age T, whichever occurs first. The system is assumed having experienced its mission under a given operating environment and then conducted to fulfill its mission under a new operating condition. This later could be more or less severe that the first and does impacts the system lifetimes distribution. In this paper unlike of the most existing approaches, the system lifetimes distribution is assumed unknown but rather estimated from lifetime data. To estimate the reliability of the system, the Kernel methods is exploited. Such a method offers the advantage of non-parametric estimation methods and in addition to be easy to implement. First, we show that the smoothing parameter of the Kernel estimator has no effect on the estimated values of the system reliability. Second, a mathematical cost model is derived on the basis of Kernel estimator so as to evaluate the optimal preventive age replacement of the system under the new operating environment. The impact of the variability of Kernel smoothing parameter on the cost model is studied, and conditions under which an optimal preventive maintenance age exists, are provided. A numerical example is given to illustrate the proposed work. |

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.
