Functional cascading and abstracted energy model in systems engineering and model‐based development

Systems engineering (SE) and model‐based development (MBD) attract attention from manufacturers to produce more complex products with less rework in order to satisfy higher demands. However, concrete methodology is not defined well. This paper proposes a methodology of target assignment with respect to a special functional cascading for integrated atchitectural products. This paper also proposes “abstracted energy model” for assignment in top layer in the cascade. An example for air conditioner development demonstrates the efficiency of this methodology.
