Abstract
As current practice of product design involves numerous number of engineers and multiple disciplines, which makes management of design process much difficult. System modelling has been introduced to provide holistic view of a product and thus to ease the management. However, depending on how a product is captured as a model, benefit of system modelling could be diminished. There are certain trait that insightful models should have. In this paper, traits of appropriate models are discussed. Further methodology for system modelling to ensure descriptions to be appropriate is proposed. To ease the modelling, computational methods to support describing appropriate model are proposed as well. Modelling of a solar boat is demonstrated as a case study.
