“…"Graphics" are widely used to express complex relationships between various engineering entities, because they can intuitively reflect the relationships between engineering objects [16]. Graphics generally consists of two parts: the complete geometric information of the building (the external contours) and the topological information of the building (the relationship formed by the graphic elements).…”

The structural components of large-scale public construction projects are more complex than those of ordinary residential buildings, with irregular and diverse components, as well as a large number of repetitive structural elements, which increase the difficulty of BIM-modeling operations. Additionally, there is a significant amount of inherent parameter information in the construction process, which puts forward higher requirements for the application and management capabilities of BIM technology. However, the current BIM software still has deficiencies in the parameterization of complex and irregular structural components, fine modeling, and project management information. To address these issues, this paper takes Grasshopper as the core parametric tool and Revit as the carrier of component attribute information. It investigates the parametric modeling logic of Grasshopper and combines the concepts of parameterization, modularization, standardization, and engineering practicality to create a series of parametric programs for complex structural components in building projects. This approach mainly addresses intricate challenges pertaining to the parametric structural shapes (including batch processing) and parametric structural attributes (including the batch processing of diverse attribute parameters), thereby ensuring the efficiency in BIM modeling throughout the design and construction phases of complex building projects.

“…At that time, a redesign of the system to eliminate the design flaws is often very expensive or even too late. Model-based systems engineering (MBSE, [5]) and corresponding tools [6] support the human engineer by allowing him to predict non-functional properties based on mathematical or simulation models, thus reducing the risks in early design decisions significantly. For safety-critical systems and highly reliable designs such properties are of equal importance as the functional requirements, especially when a certification is necessary before use -as it is often the case in train control or avionic systems.…”

Finding a good solution to an engineering problem under given constraints can be formulated as an optimization problem over a set of parameters. Existing (semi-)automatic methodologies for this task usually assume that these design parameters form a homogeneous set. The paper analyses the structure of design space and introduces the formal concept of existence-dependent parameters, which appear for instance in the optimization of system architectures. The corresponding nested optimization problems can be solved more efficiently considering the dependency relations, and will often require a mix of models and optimization algorithms. The paper proposes a completely model-driven integration methodology for such problems and a prototype tool combining several existing domain-specific tools. An application example from the area of distributed embedded systems design of hardware architecture and software mapping demonstrates the applicability.
