The system is subject to condition monitoring and the degradation process is described by a hidden Markov model. A cost-optimal Bayesian control policy is developed for maintaining the system. The control problem is formulated in the semi-Markov decision process framework. An effective computational algorithm is developed, illustrated by a numerical example. }, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {8}, number = {9}, year = {2014}, pages = {1543 - 1547}, ee = {https://publications.waset.org/pdf/9999273}, url = {https://publications.waset.org/vol/93}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 93, 2014}, }
