| Abstract | Validation of computer system simulation models is a common concern of both the programmer/analyst and the decision maker. This paper addresses the question of what are the major characteristics of the empirical aspects of validation and how one might carry out such a validation process for complex computer system models. Validation is described in terms of verification of the authenticity of the random number and random variate generators and of the independent variables established for the model, a proper choice of dependent (response) variables to observe in both the simulation model and the actual system itself (i.e., two sets of data), a choice of statistical tests for comparing their distributional properties, and the ability to predict system performance based on future changes in the actual system configuration. The concepts of validation are clarified through the example of an actual detailed model constructed for the input/output subsystem for a Burroughs B6700 computer. A validation process is proposed which specifies data that should be collected from the simulation model, which relates experiences with obtaining the coordinate live test data from the actual system under consideration, and finally shows how statistical tests can be applied to verify or reject the hypothesis that both sets of data result from the same population. Empirical data is presented to aid in the understanding of the concepts. |

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.
