Abstract: The availability and maintainability of a machine or equipment is the most important parameter in deciding the performance level of any organization. Hence, the managers would be very much interested to keep their machines or equipment available for maximum Hours without any failures. Also proper maintenance of machine or equipment and its periodic conditioning play a vital role in restoring the system after a repair. All these necessitate every manager and engineer to focus on availability and maintainability of machine or equipment. This study was taken up to evaluate the availability and maintainability of TSRTC buses to improve the profits and to minimize the customer dissatisfaction. The data regarding the bus failures for the period of one year has been collected and MTBF and MTTR have been calculated for each bus separately which are essential in finding the availability and maintainability. The results have been categorized as high, medium and low, and arranged in the matrix as a cluster based on their results. The focus on the buses which are at most extremities in the matrix may considerably maximize the availability and also the profits to the organization.
