Abstract— This paper proposes a simple analytical model called time-scale Markov Decision Process (MMDP) for hierarchically struc-tured sequential decision making processes, where decisions in each level in the -level hierarchy are made in different discrete time-scales. The MDP explicitly attempts to match staffing with demand, has a statistical discrete time Markov chain foundation that estimates the service process, predicts transient inventory, and is formulated for an inpatient unit. Abstract — Markov decision processes (MDPs) are often used to model sequential decision problems involving uncertainty under the assumption of centralized control. Two attack scenarios are studied to model different knowledge levels of the intruder about the dynamics of power systems. Such performance metric is important since the mean indicates average returns and the variance indicates risk or fairness. The rewards axe time discounted. In this paper, we formulate the service migration problem as a Markov decision process (MDP). To represent probabilities that are needed when planning under uncertainty, we introduce factored Petri nets; we then describe the conversion of factored Petri nets in Markov decision processes.

The best actions by the defender can be characterized by a Markov Decision Process in a case of partially observability and importance of time in the expected … Abstract: This paper presents a novel method-continuous-time Markov decision process (CTMDP)-to address the uncertainties in pursuit-evasion problem. An MDP is a tuple, (S , A, P a ss0, R a ss0, ⇥ ), where S is a set of states, A is a set of actions, P a ss0 is the probability of reach-ing state s0 after taking action a in state s, and Ra ss0 is the reward received when that transition occurs, and ⇥ ⌅ [0, 1] is a discount rate parameter. The processes are assumed to be finite-state, discrete-time, and stationary. In this paper, we first study the influence of social graphs on the offloading process for a set of intelligent vehicles. Bayesian hierarchical models are employed in the modeling and parametrization of the transition probabilities to borrow strength across players and through time.

Paolucci, Suthers, & Weiner 1996) and item recommendation (e.g. Lastly, the MDP application to a telemetry unit reveals a computational myopic, an approximate stationary, … R. On each round t, A mode basically indexes a Markov decision process (MDP) and evolves with time according to a Markov chain. We propose an online Markov Decision Process to model the stochastic dynamic decision making process of condition-based maintenance assuming bathtub shaped failure rate curves of single units, which is then embedded into a non-convex MINLP (DMP) that considers the trade-o among all the decisions. framework of partially observable Markov decision pro-cesses (POMDPs2) [9]–[11]. In this paper, we consider a Markov decision process (MDP) in which the ego agent intends to hide its state from detection by an adversary while pursuing a nominal objective.

Numerical … Mobile Edge Offloading Using Markov Decision Processes, Smart grid-aware radio engineering in 5G mobile networks. Abstract In this paper we show that for a finite Markov decision process an average optimal policy can be found by solving only one linear programming problem. In this paper, we introduce the notion of a bounded-parameter Markov decision process(BMDP) as a generalization of the familiar exact MDP. that is, after Bob observes that Alice performs an action, Bob is deciding which action to perform, and further Bob’s execution of the action will also affect the execution of Alice’s next action. Want create site? Introduction Process reliability is important to chemical plants, as it directly impacts the availability of the end product, and thus the pro tability. This paper focuses on the linear Markov Decision Process (MDP) recently studied in [Yang et al 2019, Jin et al 2020] where the linear function approximation is used for generalization on the large state space. However, the variance metric couples the rewards at all stages, the … [0;1], and a reward function r: SA7!
