| process of mapping a source model, called a base_modelinto a target model, called a lumped_model. This process involves grouping base_model elements and combining each such group into a single lumped_modelelement. Grouped elements thus become indistinguishable in the target model. Aggregation is a simplification_procedureand a form of abstraction. usually done with the intention of creating a homomorphic_model representation within an experimental_frame | |||||||||||||||||||
