SECTION 1.2 Refinement for Fault-Tolerance: An Aircraft Hand-off Protocol
Part of the Advanced Automation System (AAS) for air-traffic control is a protocol to permit flight hand-off from one air-traffic controller to another. The protocol must be fault-tolerant and, therefore, is subtle—an ideal candidate for the application of formal methods. This paper describes a formal method for deriving fault-tolerant protocols that is based on refinement and proof outlines. T...
متن کاملRigorous Development of Fault-Tolerant Systems through Co-refinement
With our increasing dependency on computer-based systems, ensuring their dependability becomes one the most important concerns during system development. This is especially true for missionand safety-critical systems. Critical systems typically use fault tolerance mechanisms to mitigate runtime errors. However, fault tolerance modelling and, in particular, rigorous definitions of fault toleranc...
متن کاملFault Tolerant Control for Damaged Aircraft Based on Sliding Mode Control Scheme
In this paper, the problem of structural damage with partial loss vertical tail in aircraft dynamical system is investigated. A linearized aircraft model is introduced firstly, then a damage-tolerant controller based on an adaptive sliding mode control is proposed. Finally, simulations with an aircraft model are conducted to demonstrate the effectiveness and advantages of the proposed design te...
متن کاملComputing Science Refinement Patterns Bibliographical Details Suggested Keywords Refinement Patterns
Formal methods focus on a posteriori analysis and a modeller gets little assistance in constructing a model. Poor methodological and tool support means formal modelling is an expensive and laborious process which can produce poor quality specifications. Refinement patterns offer a constructive top-down approach to formal modelling by guiding a developer and providing reusable design solutions. ...
متن کاملStability Assessment Metamorphic Approach (SAMA) for Effective Scheduling based on Fault Tolerance in Computational Grid
Grid Computing allows coordinated and controlled resource sharing and problem solving in multi-institutional, dynamic virtual organizations. Moreover, fault tolerance and task scheduling is an important issue for large scale computational grid because of its unreliable nature of grid resources. Commonly exploited techniques to realize fault tolerance is periodic Checkpointing that periodically ...
متن کاملIncremental Fault-Tolerant Design in an Object-Oriented Setting
With the increasing emphasis on dependability in complex, distributed systems, it is essential that system development can be done gradually and at different levels of detail. In this paper we propose an incremental treatment of faults as a refinement process on object-oriented system specifications. An intolerant system specification is a natural abstraction from which a fault-tolerant system ...
