| Abstract | World steel trade becomes more competitive every day and new high international quality standards and productivity levels can only be achieved by applying the latest computational technologies. Data driven analysis of complex processes is necessary in many industrial applications where analytical modeling is not possible. This paper presents the deployment of KDD technology in one real industrial problem: the development of new tinplate quality diagnostic models.The electrodeposition of tin on steel strips is the most critical stage of a complex process that involves a great amount of variables and operating conditions. Its optimization is not only a great commercial and economic challenge but also a compulsion due to the social impact of the tinplate product-more than 90% of the production is used for food packaging. The necessary certification with standards, like ISO 9000, requires the use of diagnostic models to minimize the costs and the environmental impact. This aim has been achieved following the multi-stage DM methodology CRISP-DM and a novel application of pro-active maintenance methods, as FMEA, for the identification of the specific process anomalies. Three DM tools have been used for the development of the models. The final results include two ANN tinplate quality diagnostic models, that provide the estimated quality of the final product just seconds after its production and only based on the process data. The results have much better performance than the classical Faraday's models widely used for the estimation. |

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.
