Abstract: The objective of this paper is to design a suitable maintenance schedule by assessing the condition of the buses using TTT and Weibull’s plots and finding out Toptimal period of buses. Toptimal  period helps in fixing the maintenance schedule of each bus. This will help in improving the availability of buses for operation and hence to the productivity improvement of the organization.

Key Words: Reliability, TTT plots, Weibull’s plots, Toptimal, Maintenance schedules
