System Modeling and Simulation in Computer-Based Systems

Blanchard and Fabrycky define a set of criteria for the use of models during Technical analysis of systems: The model should accurately represent the system configuration’s dynamics, making it easy to understand and manipulate while maintaining closeness to the operating reality for accurate results. The models should highlight those factors that are most relevant to the problem at hand and suppress (with discretion) those that are not as important. Model design should be simple and efficient for timely problem-solving. For complex models, smaller models with interconnected outputs or independent evaluation of system elements may be beneficial, ensuring efficient use by analysts or managers. Model design should allow for easy modification and expansion, often involving trials to identify information gaps and suggest beneficial changes before achieving the overall objective. Modeling the System Architecture: Computer-based systems can be modeled using input-processing-output architecture, with Hatley and Pirbhai extending this to include processing, user interface processing, maintenance, and self-test. These features make system models more robust, allowing engineers to create a foundation for requirements analysis and design steps. Figure 9. Architecture Template To develop the system model, an architecture template is used. The key to effective system engineering hierarchy is to create a clear structure that defines the relationships between different levels of abstraction. This hierarchy helps in breaking down complex systems into manageable components, ensuring a systematic approach to system development. At the top of the system engineering hierarchy is the _________ level, which provides an overarching view of the system's purpose and goals.

System modeling is essential in system engineering as it allows for a detailed representation of the system's components and their interactions. By creating models that accurately depict the system's behavior, engineers can analyze and optimize the system's performance. Domain elements are the fundamental building blocks of a system model, representing the various aspects and components of the system. These elements include input variables, output variables, constraints, and relationships between different parts of the system. By defining domain elements, engineers can develop a comprehensive understanding of the system's structure and behavior, leading to more effective system design and analysis. When creating a system model, it is important to consider the _________ components that make up the system.

Blanchard and Fabrycky emphasize the importance of using models that accurately capture the system's dynamics and configuration. These models should be designed to be easy to understand and manipulate, ensuring that analysts and managers can use them effectively for problem-solving. One key aspect of modeling is to highlight the most relevant factors while suppressing less important ones. This selective emphasis helps in focusing on critical aspects of the system and simplifying the analysis process. When designing a system model, it is crucial to ensure that the model is both simple and efficient to facilitate timely problem-solving. Additionally, the model should allow for easy modifications and expansions to adapt to changing requirements and new information. In system modeling, creating smaller interconnected models or independently evaluating system elements can enhance the efficiency and usability of the models. This approach aids in breaking down complex systems into more manageable components, making it easier for analysts and managers to work with the models. The key to effective system modeling is to strike a balance between highlighting relevant factors and suppressing _________ ones.
