2.3. Application example: Smart-Home systems
To better explain the basis of MDE and SPLE, and to
demonstrate the feasibility and economies of our approach,
we consider two examples from two different domains. In this
chapter, we introduce the first one. This is a home automation
system, which is rather a classic application of product lines.
The second one is introduced and developed in Chapter 7. It
has more characteristics of information system applications
where we need to manage, present, and store several pieces
of information of a business domain.
The Smart-Home illustrative example is taken from
the domain of home automation.
“A smart home is a
building for living equipped with a set of electrical and
electronic sensors and actuators in order to allow for an
intelligent sensing and controlling of the building's devices:
windows, heaters, lights, etc.”
[ELS 08]. This application
example was also exploited in several other projects, for
instance in the AMPLE project [RAS 11] and in Pohl's
topic [POH 05b].
2.3.1.
Smart-Home system's domain
Smart-Homes are equipped with a wide range of electronic
and electrical devices, such as light arrays, temperature
sensors, thermostats, electrically steered blinds and windows,
door sensors,door openers,etc.A Smart-Home software system
coordinates and controls such devices enabling inhabitants
to manage them from a common user interface. A Smart-
Home system offers high-level functionality where several
