In this paper, a condition‐based maintenance model for a multi‐unit production system is proposed and analyzed using Markov renewal theory. The units of the system are subject to gradual deterioration, and the gradual deterioration process of each unit ...

Asymptotic Optimality of Semi-Open-Loop Policies in Markov Decision Processes with Large Lead Times
Operational Research, 2023A generic way to verify asymptotic optimality of semi-open-loop policies for a wide class of MDPs with large lead times. In many real-life inventory models, order lead times can result in uncertain effects of inventory decisions.

Policy Gradient Semi-markov Decision Process
2008 20th IEEE International Conference on Tools with Artificial Intelligence, 2008This paper proposes a simulation-based algorithm for optimizing the average reward in a parameterized continuous-time, finite-state semi-Markov decision process (SMDP). Our contributions are twofold: First, we compute the approximate gradient of the average reward with respect to the parameters in SMDP controlled by parameterized stochastic policies ...

Optimal Fidelity Selection for Human-in-the-loop Queues using Semi-Markov Decision Processes
American Control Conference, 2019We study optimal fidelity selection for a human operator servicing a queue of homogeneous tasks. The service time distribution of the human operator depends on her cognitive dynamics and the level of fidelity selected for servicing the task.

Risk-sensitive semi-Markov decision processes with general utilities and multiple criteria
Advances in Applied Probability, 2018In this paper we investigate risk-sensitive semi-Markov decision processes with a Borel state space, unbounded cost rates, and general utility functions. The performance criteria are several expected utilities of the total cost in a finite horizon.

Semi-Markov Decision Process With Partial Information for Maintenance Decisions
IEEE Transactions on Reliability, 2014A critical factor that prevents optimal scheduling of maintenance interventions is the uncertainty regarding the current condition of the asset under consideration, as well as the rate at which deterioration takes place. However, current maintenance modeling and optimization techniques assume that the condition of the asset is either known, or assumed ...
