Is it a management system which, according to a set of rules and trends, controls complex systems. One type of regulation is program regulation which uses the right order of condition in a given time. The program regulation is one of the easiest regulations for users.

Of course there are many more devices which use program regulation, for example the kettle, but I think that washing machine is a great example to show how work program regulation.
