Query: A Framework for Plant Topology Extraction Using Process Mining and Alarm
  Data   Industrial plants are prone to faults. To notify the operator of a fault
occurrence, alarms are utilized as a basic part of modern computer-controlled
plants. However, due to the interconnections of different parts of a plant, a
single fault often propagates through the plant and triggers a (sometimes
large) number of alarms. A graphical plant topology can help operators, process
engineers and maintenance experts find the root cause of a plant upset or
discover the propagation path of a fault. In this paper, a method is developed
to extract plant topology form alarm data. The method is based on process
mining, a collection of concepts and algorithms that model a process (not
necessarily an engineering one) based on recorded events. The event based
nature of alarm data as well as the chronological order of recorded alarms make
them suitable for process mining. The methodology developed in this paper is
based on preparing alarm data for process mining and then using the suitable
process mining algorithms to extract plant topology. The extracted topology is
represented by the familiar Petri net which can be used for root cause analysis
and discovering fault propagation paths. The methods to evaluate the extracted
topology are also discussed. A case study on the well-known Tennessee Eastman
process demonstrates the utility of the proposed method.
