The CC technique accounts for more than 60% of total liquid steel in the world. Thus, the applied reliability modeling and analysis of a CC plant is of great importance; and hence, the paper explores a real, case specific modeling and analysis of a CC plant, where two 200 ton (unit I) and two 100 ton (unit II) EOT cranes are operating in parallel. Both units operate at full installed capacity and priority for maintenance and operation is given to the unit with higher installed capacity. When a unit fails, it is inspected to decide the type of maintenance job to be performed. The components are then repaired, replaced or reconditioned/reinstalled as required. Optimized reliability indices of the plant are obtained using semi-Markov processes and regenerative point techniques. Profit incurred to the CC plant is also evaluated and graphs pertaining to these indices are plotted
