Estimators of parameters of the exponential family distributions and maintenance problem.
In this paper we suggest a tabular structure for maintenance or reliability data. Also we propose a cost implication model of a preventive maintenance policy in which we included the average cost of downtime of the unit. Maximum likelihood and moment methods of estimations are used on some of the Exponential Family distributions; to make comparative study of the estimators and to demonstrate the application of the models presented with an arbitrary sampled data.
