Formulation of MDP problem is presented using the information about the current state of pipe, improvement cost, failure cost and pipe deterioration model. The objective function and detailed algorithm of dynamic programming (DP) are modified due to the difficulty of implementing the conventional DP approaches. The optimal schedule derived from suggested model is compared to several policies via Monte Carlo simulation. Validity of the solution and improvement in computational time are proved. }, journal = {International Journal of Civil and Environmental Engineering}, volume = {9}, number = {4}, year = {2015}, pages = {277 - 282}, ee = {https://publications.waset.org/pdf/10000986}, url = {https://publications.waset.org/vol/100}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 100, 2015}, }
