Model-Based Appliances Design Approach:
Over the years appliance time to market is shortening and the model support in
the appliance design is always increasing its value. Different model typologies are
currently used in the project development:
• Synthesis models are used in the concept phase to support the technological
decision making and the component sizing.
• Thermodynamic and performance models are a strong support in the duty
cycle set up and in the performance optimization. The optimum working
conditions are defined with numerical tests using the DoE approach.
• Structural and dynamic models are used in the design definition of the
critical components.
The models become a knowledge asset for Indesit Dish Washer and some flash
relating to other wet products and a basis for the future products development.

Synthesis models to
validate the feasibility
of the concept and to
define the general
characteristics of the
product.
Concept Development
Dynamical and structural models to support the designers in the
components definition. Fluid dynamic models to verify circuits
feasibility. Thermodynamic models to test the design performances.
Design
Syhthesis model for the virtual
evaluation of the performance
and the duty cycle set up.
Technical demonstrator
Production Ramp-Up
Virtual lab for the use interface and esthetics verification and set up.

CONSORZIO ITALIANO DI RICERCA SULLA DOMOTICA
Start up in April 2011
President: Andrea Merloni
The main aim of the consortium is to promote:
• research, innovation and technological development among
the various products and services within the home
• promote the introduction, management and dissemination of
new technologies related to the world of domestic dwellings
and all the related aspects
• consumption reduction, energy efficiency, micro-
generation of energy, remote control and home
automation, support and monitoring of people with reduced
mobility / cognitive, the active and passive safety

Conclusions
Indesit is currently implementing a methodological path for the Model-Based Design Approach.
The models become a knowledge asset for Indesit and a basis for the future products development.
Till 2002
• Into the single R&D: it was used on spot to fix up urgent issues.
2003-2010
• Centralized: a unique simulation team to support all the BU. Planning of the simulations to reduce the development effort and time.
From 2011
• Into the BU: the knowledge and simulation model Indesit acquired in the previous years have been introduced in the single product lines.
