On the other hand, we would try to make a simple question if those new generation factories
suffer some sort of a business discontinuity for a reason of some systematic failures or
unobvious reasons. The capacities of those production systems are huge and it’s obvious how
big the economical losses could be if the factory would suffer the frequent stoppage in its
production. This could be some systematic mistake for real, but so commonly the reasons are
more bizarre.

The engineers and technicians working in those high tech factories could believe that they
would suffer the flaws because the technology is still new and many aspects of its design are
still unexplored. Right here, we would point a concern to more obvious physical phenomenon
being the interference. Some researchers would do the great studies about those challenges
being present at the busy places such are the airports. They would indicate that the signal could
get amplified, damped or deformed depending on the sort of interference you are dealing with.

Just try to imagine that you deal with the constructive interference that would so greatly amplify
your signal and make a receiver dealing with so to simply get burnrd because of such a strong
electromagnetic wave. The receiver itself would get in touch with that strong signal and it would
induce electricity it cannot deal with. So, as a consequence of such an occurrence – we could
have a damage of the entire receiving part.

As it’s known – the industrial systems would basically deal with a plenty of sensors, controllers
and actuators. You would agree with us it would not be convenient at all if some of those
subsystems would simply burn for a reason of high voltage. In such a case, we would appeal on
system’s designers to pay attention on a good calibration as well as reliable fusing elements
that would save those segments from damage. Also, it could happen that the interference would
be destructive meaning that the entire signal could get damped.

In that case, nothing would happen or – in other words, the production system would not receive
any signal on. This would get identified as a stoppage in production and the technical service
would spend some time trying to discover what happened for real which would also affect the
business continuity.

Finally, receiving some sort of shifted or deformed signal would damage the information that
would come at its destination causing the flaws in the entire operation.

Through the following series of illustration we would try to demonstrate how constructive,
destructive and inbetween interferences appear in a practice. The illustrations being provided
here are drawn using the GRAPH mathematical tool and their purpose would be to show
through simple periodic functions such as sinus and cosine how it works in a theory.

We would highlight that the cases from the practice are much more complicated and they need
a detailed mathematical analysis to get understanded. Let’s start with the constructive
interference being given in a Figure 1.
