The use of such mathematical models and simulations avoids actual experimentation, which can be costly and time-consuming. Users should be able to perform system analysis, create dependency matrices, run simulations, and produce a view of the system for every stakeholder. Models can be composed of different units (models at finer granularity) linked to achieving a specific goal; for this reason they can be also called modeling solutions. A successful example to be copied, with or without modifications. One example is heteroskedasticity and using WLS to address it. A particular version or design of an object that is made in multiple versions; as, the 1993 model of the Honda Accord; the latest model of the HP laserjet printer.
