| Abstract | There are two problems of the traditional life and reliability estimation methods of Accelerated Life Test (ALT): one is the difficulty to establish the accelerated model and another is the complex computing of multiple likelihood equations. In this paper, we proposed a new prediction method of life and reliability for the constant stress accelerated life test using Grey RBF Neural Network. The accelerated stress levels and reliability are used as the training input vectors, while well-regulated failure data operated by Grey Accumulated Generate Operation (AGO) principle as training target vectors. Then RBF neural net is established and trained. Eventually, the failure data under normal stress can be predicted by putting the normal stress levels and the reliability into the model, and reliability curves can be drawn if life distribution is known. A simulation case is conducted and results are compared to that of BP algorithm, which demonstrates the validation of this model. |

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.
