Deliberation scheduling using GSMDPs in stochastic asynchronous domains

Kurt D. Krebsbach
2009 International Journal of Approximate Reasoning  
We demonstrate a significant improvement in expressibility over previous discrete-time approximate models in which mission phase duration was fixed, failure events were synchronized with phase transitions  ...  We propose a new decision-theoretic approach for solving execution-time deliberation scheduling problems using recent advances in Generalized Semi-Markov Decision Processes (GSMDPs).  ...  Because reasoning about these units of deliberation involves both deciding which actions to take (planning) and when to take them (scheduling), we refer to the problem as one of deliberation scheduling  ...

Fuzzy scheduling of job orders in a two-stage flowshop with batch-processing machines

Alebachew D. Yimer, Kudret Demirli
2009 International Journal of Approximate Reasoning  
In this paper, we present a mixed-integer fuzzy programming model and a genetic algorithm (GA) based solution approach to a scheduling problem of customer orders in a mass customizing furniture industry  ...  A schedule defines the way how the batches are created from the independent jobs and specifies the processing order of the batches and that of the jobs within the batches.  ...  Computational results show that the MIFP model can be solved, in reasonable CPU runtime, for only limited number of jobs.  ...

Belief Scheduler based on model failure detection in the TBM framework. Application to human activity recognition

E. Ramasso, C. Panagiotakis, M. Rombaut, D. Pellerin
2010 International Journal of Approximate Reasoning  
A tool called Belief Scheduler is proposed for state sequence recognition in the Transferable Belief Model (TBM) framework.  ...  The Belief Scheduler makes belief on states smoother, separates the states (assumed to be true or false) and synchronizes them in order to infer the sequence.  ...  We consider the case of EDC modeling (for MLGBT the same reasoning can be applied).  ...

Approximation theorem of the fuzzy transform in fuzzy reasoning and its application to the scheduling problem

Min Liu, Degang Chen, Cheng Wu, Hongxing Li
2006 Computers and Mathematics with Applications  
Then, on the basis of the approximation theorem, a simple fuzzy number transform is constructed in order to implement the fuzzy reasoning based on multiple rules.  ...  At last, the fuzzy reasoning based on multiple rules implemented by a simple fuzzy number transform is applied to machine scheduling problems, and numerical computational results of different scale scheduling  ...  In Section 4, the approximation theory proposed is applied to the fuzzy reasoning based on multiple rules in machine scheduling problems, and numerical computational results of different scale scheduling  ...

On Providing Quality of Service in Grid Computing through Multi-objective Swarm-Based Knowledge Acquisition in Fuzzy Schedulers

R.P. Prado, F. Hoffmann, S. Garcı´a-Galán, J.E. Muñoz Expósito, T. Bertram
2012 International Journal of Approximate Reasoning  
In addition, the fuzzy scheduler with multi-objective learning results are compared to those of classical scheduling strategies in grid computing.  ...  In this sense, the role of scheduling strategies is critical and new proposals able to deal with the inherent uncertainty of the grid state are needed in a way that QoS can be offered.  ...  As studied in this section, the fuzzy rule-based meta-schedulers reasoning strategy is mainly driven by the application of the system knowledge to the system state and this way the quality of this knowledge  ...

VCG is the best anonymous scheduling mechanism

Itai Ashlagi, Shahar Dobzinski, Ron Lavi
2009 ACM SIGecom Exchanges  
Almost all state of the art mechanisms, and algorithms for merely the scheduling problem (without incentives) are anonymous, and there is no real reason to believe that there exists a non-anonymous mechanism  ...  Our main result: No anonymous mechanism for the truthful scheduling problem on unrelated machines can achieve an approximation ratio better than m.  ...

N.Mallikharjuna Rao, D.J.Samatha Naidu, J.Mithun Kumar, S.Noor Jahan
2011 International Journal of Communication Networks and Security  
Re-sults indicate that the approximation is most appropriate for a tandem network but is also reasonable for other two-dimensional topologies.  ...  This study investigates the performance of an analytical approximation for the throughput-delay charac-teristic of a multihop ad-hoc network employing conflict-free time division multiplex (TDM) scheduling  ...  Assumption D is reasonable since the schedule ensures sufficiently low interference between links scheduled to transmit during the same slot.
