Week 11 - System Architecting

    For this week, we learned about system architecting is the conceptual model that defines the structure, behavior, and more views of a system. An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the system. Architecture is associated with structures, their relationships, and expectation for their design. This applies to complex systems, such as aircraft, power plants, and spacecraft, as much as buildings. 

    There are three types of architecture. The first is functional architecture. Functional architecture is an architectural model that identifies system function and their interactions. It defines how the functions will operate together to perform the system mission. Generally, more than one architecture can satisfy the requirements. Below shows an example of a glucose meter functional architecture. 

    

    The second type of architecture is physical architecture. Physical architecture is the physical layout of a system and its components in a schema. It refers to some representation of the structure or organization of the physical elements of the system. Below is an example of physical architecture.

    The third type of architecture in system engineering is allocated architecture. The allocated architecture integrates the requirements decomposition with the functional and physical architectures. An allocated architecture contains the material needed to model the system's performance and enable trade-off decisions. It divides the design problem into chunks but the chunks are not completely independent. Below shows an example of a glucose meter allocated architecture list and allocated architecture.

    Before ending the class, Sir Zaki instructed us to do functional architecture, physical architecture, and allocated architecture based on our projects. The task should be done in words and to be presented on week 12. For the conclusion, we referred to the booklet given by Sir Zaki titled Systems Engineering Principles and Practice to do the task.
