Viewpoint on ISA TR84.0.02 Simplified Methods and Fault Tree Analysis

Abstract: ANSI/ISA-S84.01-1996 and IEC 61508 require the establishment of a safety integrity level for any safety instrumented system or safety related system used to mitigate risk. Each stage of design, operation, maintenance, and testing is judged against this safety integrity level. Quantitative techniques can be used to verify whether the safety integrity level is met. […]

Virtualization allows one computer to take the place of multiple computers, resulting in greater efficiency.

Virtualization Simplifies Computer Maintenance and Delivers High Performance

The process of virtualization works by inserting a thin layer of software called the hypervisor directly into the computer hardware. The hypervisor layer presents multiple sets of “virtual hardware,” which contain the same components as a regular machine (e.g., motherboard, chipset, etc.). To an operating system, virtual hardware is indistinguishable from a regular machine. … […]

Training Improves with Virtual Reality

Utilizing the increased power of computers, virtual reality (VR) simulates real or imaginary environments and situations with a high degree of realism and interactivity. VR is particularly good for improving the multimedia aspects of training, process design, maintenance, and safety, which are currently based around conventional 2D equipment views. Real-time rendering of equipment views places […]
