2012 Computing  
Moreover, when violations are discovered at runtime, we automatically propose and rank recovery plans which users of the system can then select for execution.  ...  For other violations, such plans include both "going back" and "re-planning" -guiding the application towards a desired behaviour.  ...  Acknowledgements Several people contributed to the ideas presented in this chapter: Shiva Nejati, Yuan Gan and Jonathan Amir were involved in various aspects of defining and building the runtime monitoring  ...

Automated runtime recovery for QoS-based service composition

Tian Huat Tan, Manman Chen, Étienne André, Jun Sun, Yang Liu, Jin Song Dong
2014 Proceedings of the 23rd international conference on World wide web - WWW '14  
In addition, the selection of recovery plans is based on their quality of service (QoS). A QoS-optimal recovery plan allows effective recovery from the state of failure.  ...  In this work, we propose an automated approach based on a genetic algorithm to calculate the recovery plan that could guarantee the satisfaction of functional properties of the composite service after  ...  Acknowledgement This work has been supported in part by research grant IDD11100102 (SUTD).  ...

2010 Proceedings of the eighteenth ACM SIGSOFT international symposium on Foundations of software engineering - FSE '10  
In this paper, we describe a user-guided recovery framework for web services.  ...  When behavioural correctness properties (safety and bounded liveness) of an application are violated at runtime, we automatically propose and rank recovery plans which users can then select for execution  ...  Acknowledgements We thank IBM CAS Toronto (specifically, Bill O'Farrell, Elena Litani and Leho Nigel), members of the IFIP 2.9 WG, and FSE anonymous reviewers for their helpful feedback on this work and  ...

Learning Policy for Robot Anomaly Recovery Based on Robot Introspection [chapter]

Xuefeng Zhou, Hongmin Wu, Juan Rojas, Zhihao Xu, Shuai Li
2020 Nonparametric Bayesian Learning for Collaborative Robot Multimodal Introspection  
In particular, we first diagnose the anomaly as accidental one at the beginning such that the reverse execution is called.  ...  In this chapter, the anomaly recovery would be acted when both of the anomaly monitoring and diagnoses are analysed, which aim to respond the external disturbances from the environmental changes or human  ...  Similarly, a recovery policy by modelling reversible execution of robotic assembly is proposed in [14] .  ...

Semantic-compensation-based recovery in multi-agent systems

A. Unruh, H. Harjadi, J. Bailey, K. Ramamohanarao
2005 IEEE 2nd Symposium on Multi-Agent Security and Survivability, 2005.  
In agent systems, an agent's recovery from execution problems is often complicated by constraints that are not present in a more traditional distributed database systems environment.  ...  An analysis of agent-related crash recovery issues is presented, and requirements for achieving 'acceptable' agent crash recovery are discussed.  ...  Effectively, for this class of repair and recovery approaches, the use of compensation/reversal is employed as a search control heuristic over the plan repair space. In Nagi et al.  ...

We propose a model for characterizing failures using this model and discuss repairs. Simple failures are by far the most common in our WRC system and we also present how we repaired them.  ...  The World Robotics Challenge (2018 & 2020) was designed to challenge teams to design systems that are easy to adapt to new tasks and to ensure robust operation in a semi-structured environment.  ...  In this section we introduce first and higher-order contingencies in the planning for this problem and discuss the recoveries.  ...
