Disturbances that spread plant-wide in a chemical process pose challenges to maintenance staff. Connections within the plant and the presence of multiple causal paths mean it is not straightforward to locate the root disturbance because the effects can propagate and be detected elsewhere. Measurementbased methods use quantitative process history to generate(More)
This contribution describes how disturbances in a control system can be isolated and diagnosed automatically based on plant topology. In order to demonstrate this, a prototype software has been designed and implemented which, when given an electronic process schematic of a plant and results from a data-driven analysis, allows the user to pose queries about(More)
Faults and disturbances in chemical process plants provide great challenges to maintenance staff in terms of the time and expenditure spent on trying to locate the root causes. Due to the complex connection of units within any plant and the numerous loops that may be present, the process of managing these faults is a large task and it is a challenge to(More)
