Model-Based Appliances Design Approach

  1. 1. Model-Based Appliances DesignApproachDino BonginiTorino, April 24th 2013
  2. 2. Dedicated to families who find in their home the expression of theirpersonality and their style. People who seek for innovativeappliances that guarantee excellent results.About Indesit Company2Sales in 2012:Euro 2.9 billionOutright leader in:Italy, Russia, the UK, Ukraine.Three Brands, a solution for every lifestyle.
  3. 3. 3Model-Based Appliances Design Approach:Over the years appliance time to market is shortening and the model support inthe appliance design is always increasing its value. Different model typologies arecurrently used in the project development:• Synthesis models are used in the concept phase to support the technologicaldecision making and the component sizing.• Thermodynamic and performance models are a strong support in the dutycycle set up and in the performance optimization. The optimum workingconditions are defined with numerical tests using the DoE approach.• Structural and dynamic models are used in the design definition of thecritical components.The models become a knowledge asset for Indesit Dish Washer and some flashrelating to other wet products and a basis for the future products development.

  15. 15. ConclusionsIndesit is currently implementing a methodological path for the Model-BasedDesign Approach.The models become a knowledge asset for Indesit and a basis for the futureproducts development.Till 2002• Into the singleR&D: it wasused on spot tofix up urgentissues.2003-2010• Centralized: auniquesimulationteam tosupport all theBU. Planningof thesimulations toreduce thedevelopmenteffort and time.From 2011• Into the BU:the knowledgeand simulationmodel Indesitacquired in theprevious yearshave beenintroduced inthe singleproduct lines.
