Abstract | A condition-based maintenance model for periodically inspected systems subject to degradation and random shocks is addressed in this paper. Upon inspection, one will need to determine whether to perform a preventive maintenance, corrective maintenance, or to do nothing. In this paper, we present an expected maintenance cost rate model for systems subject to a degradation process and cumulative shock damage. An optimal maintenance policy consisting of two decision variables such as the preventive maintenance threshold and periodical inspection time, is determined that minimizes the expected long-run maintenance cost per unit time. To improve the search and better ways to obtain the optimum solution, we also propose a heuristic algorithm procedure based on the mean time to first failure concept in order to find the best optimum solution. A numerical example is given to illustrate the ideas of modeling and algorithms. |

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.
