| Abstract | Degradation is an inevitable course of any manufacturing tool, machine or system. The degradation of the health state of manufacturing tools results in some sort of an ineludible maintenance action which could be both costly and happening in a critical production time. In most manufacturing systems, a fleet of identical machines are assigned different tasks towards satisfying requirements within the production process. We introduce a degradation-based resource allocation policy to optimally utilize a fleet of identical machines. The policy, denoted as Degradation Based Swapping Optimization (DBSO), incorporates the optimal implementation of swapping scheduled tasks and scheduling maintenance actions throughout a finite time horizon to minimize projected maintenance costs and/or utilize the manufacturing productivity towards pre-specified logistics objectives. A mathematical model for the policy is provided and this model is optimized using elitist genetic algorithm and simulated annealing algorithm where numerical results have been introduced. The proposed policy succeeds in establishing substantial savings in the simulated example which amount to 43% of the estimated maintenance costs in comparison to the scenario where fixed scheduling is applied. |

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.
