A Decentralized Partially Observable Markov Decision Model with Action Duration for Goal Recognition in Real Time Strategy Games

Discrete Dynamics in Nature and Society, Volume 2017, Issue 1, 2017., 2017
Multiagent goal recognition is a tough yet important problem in many real time strategy games or simulation systems. Traditional modeling methods either are in great demand of detailed agents’ domain knowledge and training dataset for policy estimation or lack clear definition of action duration.

A Semi‐Markov Decision Model for Recognizing the Destination of a Maneuvering Agent in Real Time Strategy Games

Mathematical Problems in Engineering, Volume 2016, Issue 1, 2016., 2016
Recognizing destinations of a maneuvering agent is important in real time strategy games. Because finding path in an uncertain environment is essentially a sequential decision problem, we can model the maneuvering process by the Markov decision process (MDP). However, the MDP does not define an action duration.

Transient Analysis of a k‐out‐of‐n:G System with N‐Policy, Repairmen’s Multiple Vacations, and Redundant Dependency

Discrete Dynamics in Nature and Society, Volume 2015, Issue 1, 2015., 2015
This paper analyzes a k‐out‐of‐n:G repairable system with N‐policy, repairmen’s multiple synchronous vacations, and redundant dependency. When there is no failed component in the system, the repairmen leave for a vacation, the duration of which follows a phase type distribution.

A Logical Hierarchical Hidden Semi‐Markov Model for Team Intention Recognition

Discrete Dynamics in Nature and Society, Volume 2015, Issue 1, 2015., 2015
Intention recognition is significant in many applications. In this paper, we focus on team intention recognition, which identifies the intention of each team member and the team working mode. To model the team intention as well as the world state and observation, we propose a Logical Hierarchical Hidden Semi‐Markov Model (LHHSMM), which has advantages ...

Phase‐type models involving restarting and instantaneous transitions, with applications to degradation and maintenance

Applied Stochastic Models in Business and Industry, Volume 40, Issue 3, Page 668-683, May/June 2024.
Abstract A phase‐type distribution is the distribution of time to absorption for an absorbing continuous‐time finite state Markov chain. The paper first reviews the extension of the phase‐type setting to modeling of competing risks by introducing multiple absorbing states.

Análisis de trayectorias estudiantiles mediante distribuciones de fase discretas acíclicas

Revista Latinoamericana de Estudios Educativos
En este trabajo se analizan las trayectorias estudiantiles mediante mezclas de distribuciones de fase discretas acíclicas. El modelo propuesto combina una distribución de Coxian discreta para estimar las probabilidades de deserción en los semestres ...

On the reliability of a renewable multiple cold standby system

Mathematical Problems in Engineering, Volume 2005, Issue 3, Page 269-273, 2005., 2005
We present a general reliability analysis of a renewable multiple cold standby system attended by a single repairman. Our analysis is based on a refined methodology of queuing theory. The particular case of deterministic failures provides an explicit exact result for the survival function of the duplex system.
