A unified approach for semi-Markov decision processes with discounted and average reward criteria
Proceeding of the 11th World Congress on Intelligent Control and Automation, 2014On the basis of the sensitivity-based optimization, we develop a unified optimization approach for semi-Markov decision processes (SMDPs) with infinite horizon discounted and average reward criteria. We show that the sensitivity formula under average reward criteria is a limitation case of discounted reward criteria.

This paper deals with the ratio and time expected average criteria for constrained semi-Markov decision processes (SMDPs). The state and action spaces are Polish spaces, the rewards and costs are unbounded from above and from below, and the mean holding times are allowed to be unbounded from above. First, under general conditions we prove the existence

Wheels are one of the three components of rail vehicles that are most affected by wear, having significant implications on safety and comfort. For the safety of vehicles, maintenance activities are needed for worn wheels to ensure their normal geometry, where reprofiling plays the most important role in maintenance.

In Figure 4.1(a) a diagrammatic representation of a semi-Markov decision process is presented; special attention to transition probabilities \( \left[ {\mathop p\nolimits_{ij,}^k } \right]\) and waiting time probabilities \( \mathop h\nolimits_{ij(m)}^k \) is given.

Optimality problems in infinite horizon discrete time vector criterion Markov and semi-Markov decision processes can be expressed as standard problems of multiple objective linear programming. “VMDP” is a FORTRAN program for enumerating the objective function coefficients and constraint coefficients in these problems and finding all nondominated ...

Abstract : Semi-Markov decision processes with countable state and action spaces are investigated. The optimality criteria considered are the average cost criterion, the undiscounted cost criterion, and the discounted cost criterion. The common assumption of bounded costs has been replaced by some considerably weaker conditions.
