Toward an Intelligent Distributed Safety Instrumented Systems: Dependability Evaluation

Dependability Evaluation of Cluster-Based Distributed Systems

Awerbuch and Scheideler have shown that peer-to-peer overlay networks can survive Byzantine attacks only if malicious nodes are not able to predict what will be the topology of the network for a given sequence of join and leave operations. In this paper we investigate adversarial strategies by following specific protocols. Our analysis demonstrates first that an adversary can very quickly subve...

Intelligent Robotic Systems: Safety, Security, Health, and Dependability

Safety Instrumented Systems - Health Monitoring

The unique SIS-Health Monitoring solution is a set of tools and services that enable industry practitioners to measure the status and health of their safety instruments, analyze their reliability and safety integrity, optimize test intervals, and reduce spurious process trips. In addition, the SISHealth Monitoring solution enables the detection of unexpected trends, the maintenance of test freq...

Dependability Evaluation of Fault Tolerant Distributed Industrial Control Systems

Abstract. Modern distributed industrial control systems need improvements in their dependability. In this paper we study the dependability of a fault tolerant distributed industrial control system designed in our university. This system is based on fault tolerant nodes interconnected by two communication networks. This paper begins showing the architecture of a single node in the distributed sy...

Selecting Transmitters for Safety Instrumented Systems

Users design safety systems to mitigate the risk of identified process hazards within tolerable levels, using application-specific risk models, defined user inspection schedules, and safety data for the devices under consideration. Some suppliers provide safety data for their devices. However, supplier data, even when validated by a third party, reflects laboratory results, and can be an order ...
