Machine Diagnostic Expert System Demos
Equipment often malfunctions. Fixing it can be relatively cheap once you have found out what the problem actually is. VisiRule charts map well on to the top-down approach taken by engineers. In a similar way to Field Service Engineers and Support Reps, the expert system asks the most important questions first and gradually guides the analysis to a successful problem resolution.
Once the fault has been diagnosed, VisiRule can make suggestions for how to fix the problem or, in the short term, what compensatory actions can be implemented whilst awaiting a more permanent fix.
Pre-emptive and Predictive Maintenance
There's a well known Chinese saying: "Cure the disease before it has happened". It far more economical to detect an oncoming problem fault in advance and take preemptive actions, as opposed to waiting for the thing to break.
Modern technology can enable product knowledge to be commoditized and offered to a wide audience to win new business and secure existing business. Expert system software has been around for many years and provides a rules-based approach to knowledge capture and execution. Diagnostic expert systems provide a convenient way of making specialist expert knowledge available to a wide audience.
And, where historical data exists, VisiRule can benefit from Machine Learning techniques to help generate the rules for the chart.
VisiRule can also incorporate pre-existing data such as wiring diagrams and user manuals. In fact, the main difference is that, unlike the human expert, the virtual engineer is always available, 24x7, in any location, and, on any device. This means you can provide a guided, interactive service to assist both your staff, agents, dealers and customers alike. This in turn reduces the strain on your own resources whilst increasing customer satisfaction.
Many of the demos on this page come from Morris Rosenthal and his excellent site at www.ifitjams.com.

Do the brakes fail to stop the car?
If you have to step on the brake pedal harder than you want to in order for the brakes to operate normally, the brakes do stop the car. What we're interested in here is when you have to push on the pedal with both feet and the car slowly rolls to a stop rather than locking up the wheels, or when the pedal goes to the floor, won't pump up, and you have to yank the emergency brake or turn the engine off in gear in order to slow it down.
Includes a simple chatbot to fast track you directly to the right part of the diagnostic tree based.
