Minimal Instrumentation May Compromise Failure Diagnosis With an Ecological Interface
Interfaces designed according to ecological interface design (EID) display higher-order relations and properties of a work domain so that adaptive operator problem solving can be better supported under unanticipated system conditions. Previous empirical studies of EID have assumed that the raw data required to derive and communicate higher-order information would be available and reliable. The ...
متن کاملDesigning a Process Flowsheet
The appearance and form of piping and instrumentation diagrams (P&IDs) have changed little over time, despite decades of technology improvements. A P&ID created 60 years ago on the drawing board, using ink pens on linen sheets, describes a process the same way as one created today using modern computer-aided design (CAD) software. P&IDs continue to be fundamental references for any process faci...
متن کاملAutomated Cause & Effect Analysis for Process Plants
Cause & Effect (C&E) analysis for process plants is one of the tasks associated with Process Control Engineering (PCE). With the availability of electronic Piping and Instrumentation Diagrams (P&IDs), a Computer-Aided tool is developed to carry out the analysis automatically by encoding knowledge related to PCE in rules so that they can be applied to a given set of P&IDs to produce the correspo...

متن کاملPossibilistic Influence Diagrams
In this article we present the framework of Possibilistic Influence Diagrams (PID), which allow to model in a compact form problems of sequential decision making under uncertainty, when only ordinal data on transitions likelihood or preferences are available. The graphical part of a PID is exactly the same as that of usual influence diagrams, however the semantics differ. Transition likelihoods...
