Fault Finding Troubleshooting Flowcharts for Online Diagnostics

Decision Tree Prescriptive Analytics

VisiRule can be used for the following categories of analytics:

• Descriptive Analytics
  Model output to provide insight into the past and answer: “What happened?”

• Diagnostic Analytics
  Mine and model insight into the past and answer: “Why, How did it happen?”

• Predictive Analytics
  Use forecasting rules to understand the future and answer: “What may happen next?”

• Prescriptive Analytics
  Capture advice on possible outcomes and answer: “What can we do about it?”

 

Diagnostic Fault Finding using Troubleshooting Flow Charts

You can map out the logic needed to diagnose faults using a diagnostic fault finding flow chart or flowchart. A fault finding diagnostic flow chart provides an excellent way to capture and share the process logic that can identify the root cause and most suitable resolution. Decision tree logic flowcharts provide a natural way to direct the troubleshooting investigation.

Interactive Online Troubleshooting Guides

Questions can have links to help files, manuals, KBs, images, pictures and other useful material. Users are only ever asked questions which are relevant and will contribute to an appropriate solution being found. Using the browser, they can go back and change their mind, and see what other questions and conclusions might be considered relevant. All of this makes for a rich, interactive walk-through of the online troubleshooting process.

​

This works as both proactive and prescriptive maintenance.

 

What are Diagnostic Flow Charts?

A diagnostic flow chart is a diagram depicting a process, a system or a computer algorithm. It is a diagrammatic representation of the solution to a given problem but, more importantly, it provides a breakdown of the essential steps to solving the problem. VisiRule allows you to rapidly turn troubleshooting flowcharts into an online troushooting guide to enable staff and customers tap into the expert knowledge of your most seniors troubleshooters.

​

Why Diagnostic Expert Systems?

Expert systems have been widely used to help find faults in industrial and electrical equipment as well as deliver diagnostic advice in areas such as healthcare and customer support. Expert systems provide a systematic way to reason, extract, store and manage the expertise and know-how of senior personnel, engineers and management. This knowledge can then be used and shared with a wider range of less experienced or less specialist staff, and/or provided directly to consumers using simple interactive question and answer sessions.

 

How Can Diagnostic Expert Systems be Integrated?

Expert systems can interface to modern equipment and data feeds such as SCADA systems, PLCs and industrial controllers. Modern sensor technology and vibration data coupled with wireless or wired networks means that the intelligent remote monitoring and diagnosing of machinery is now viable. Intelligent diagnostic systems can shorten system downtime by helping identify worn parts and likely causes of failure BEFORE a part fails.

 

Knowledge Retention

Valuable knowledge can be shared and retained, even when staff members retire or leave. Prolonging the life of old equipment and being able to provide accurate and effective maintenance support systems can be aided greatly by VisiRule.

Decision Graphs - More Powerful than Decision Trees

By allowing the merging of divergent branches within the diagnostic trees, VisiRule charts support paths which join up, so reducing the unnecessary duplication of sub-trees. This 'convergence' provides a far more compact representation than traditional decision trees which are prone to 'exponential explosion'.
