| Abstract | Models are often used to characterize a complex system in analysis problems. In modeling process, it is very difficult that model parameters are determined. So, a maximum likelihood parameter determination method for complex system modeling is presented to solve this problem. Therefore, a merge method is adapted to achieve the model parameter for complex systems. The presented method is a kind of merge way and a statistics mode. The parameter values are obtained by having datum is summarized. In this text, the distribution function of unit life is established according to their probability properties. The expressions of the unit failure probability are gotten respectively. Because electromechanical system lifecycle always follows the Weibull distribution, and there are these limitations of small sample and incomplete data, the exponential distribution function is applied as a special way to determine parameter values. Then an extrapolation mode is adapted for the parameter computing. Finally, an example is explored to illustrate the proposed methods. This result is shown that presented methods are effective and feasible. And this method can be widely applied in model parameter determination for another complex system. |

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.
