The International Workshop on Reliability Theory and Survival Analysis (IWRTSA-2023) will be held during 20-22 December, 2023 at the Department of Mathematics, MIT, Manipal. This workshop intends to reach out to the community of researchers and scholars working in the broad area of Reliability Theory and Survival Analysis and also to the community in Industries and Medical Organizations involved in the applied aspect of this area. To this end, this workshop features tutorial-type lectures on engineering reliability spread over all the three days, review lectures and lectures on the application of reliability and survival analysis in industry and medical sciences. In addition, we also plan for talks on new areas of Data Science including Machine Learning and Artificial Intelligence in Reliability / Artificial Intelligence through invited/ contributory lectures emphasizing more on problem-description and their importance with a brief discussion on the corresponding solution. A limited number of research scholars will be admitted in the workshop. The interested participants are advised to register online.
