Model Generation in Design

چکیده
In designing a mechanical system, a designer uses various models of a design object . Each of the models represents a specific aspect of the design object, e.g., aspects of dynamics, hydraulics, controlling, oscillation, strength, etc. The designer refines the design object by adding properties to the models, and evaluates behaviors by calculation using the models. At the same time, since the models represents the identical object, the designer must pay attention to the consistency of the models. Although generation and consistency management of aspect-dependent models (aspect models) are central elements to be achieved by CAD, conventional CAD (Computer Aided Design) systems cannot support these tasks very well . Some sys tems can automatically generate, for instance, an FEM (Finite Element Method) model from a geometric model, but it is a fortunate case in which known algorithms work well to convert a model to another and the system does not need to know about the deep reason why the conversion works. Because the system lacks knowledge about physical laws to generate a different aspect model, in most cases the designer must build aspect models separately. ICAD (Intelligent CAD) systems are expected to serve as an integrated modeling environment in which aspect models are automatically generated and their consistency are maintained.

متن کاملDesigning a Third Generation University Model with a Combined Approach in Islamic Azad Universities of Medical Sciences
Introduction: Universities have undergone various stages in their evolutionary development. At the heart of these developments is the debate on academic entrepreneurship under the auspices of a third generation university. The theoretical and practical importance of the subject on the one hand and the lack of infrastructure studies in third generation universities in the country have led to a...
متن کاملA Switchgrass-based Bioethanol Supply Chain Network Design Model under Auto-Regressive Moving Average Demand
Switchgrass is known as one of the best second-generation lignocellulosic biomasses for bioethanol production. Designing efficient switchgrass-based bioethanol supply chain (SBSC) is an essential requirement for commercializing the bioethanol production from switchgrass. This paper presents a mixed integer linear programming (MILP) model to design SBSC in which bioethanol demand is under auto-r...
