For instance, a diagram that leans strongly towards the con… The idea of decomposing a system’s speci cation along several ‘levels of abstrac-tion’ constitutes good practice in … ). The primary difference between logical and physical architecture documentation is that, while logical architecture's concerns end with identifying functional elements of the system, physical architecture takes an additional step, specifying actual devices that those functional elements execute on. The logical architecture of a system is composed of a set of related technical concepts and principles that support the logical operation of the system. Logical architecture describes how a solution works in terms of function and logical information. Discussion Really, the only limitations are the performance and capabilities of the physical device. The architecture is rooted on F1 that corresponds to the global control-command function. Functional architecture is described as “an architectural model that identifies system function and their interactions. This means that these different … Functional and Logical Structures: A Systems Engineering Approach 2011-01-0517 Mechatronics development continues to be a challenge for automotive OEM's and suppliers. Generally, more than one architecture can satisfy the requirements, Berton Manning for the Department of Defense (DoD). In fact it allows architects to model things both at a high and low levels, depending on the requirements, which makes it very important for the architecture process. It portrays the usage of the layered architecture with the usage of 3-layers. • Derived work products, such as tables and matrices, may be used to manage these relationships and ensure coverage and traceability. From an abstraction level viewpoint, it represents a middle ground, sitting between the Conceptual and Physical architectures. Process, Functional Architecture, Logical Architecture, Technical Architecture, Model-Driven Architecture, Adaptive Cruise Control 1 Introduction Motivation. Architecture • Architecture selects the concept, decomposition and mapping of form to function • Architecture establishes the vector of design variables and operating parameters • Design selects of the values of the vector of parameters • This is what optimization is good for • Some work in “architecture… It includes a functional architecture, a behavioral architecture, and a temporal architecture. Unlike these, however, logical architecture is quite broad in scope. functional decomposition. Design vs. A logical architecture should only be created after the system’s functions and requirements are clearly defined It does not define any particular system implementation, but rather the general guidelines so as to remain solution-neutral Model Based System Engineering Concepts: Functional & Logical Architecture 7 It includes a functional architecture, a behavioral architecture, and a temporal architecture [2]. It defines how the functions will operate together to perform the system mission(s). A sub-function of interest is F1.1 which operates the train and platform doors (i.e., opening, closing, warning, etc. It defines how the functions will operate together to perform the system mission(s). It defines how the functions will operate together to perform the system mission(s). (Created for SEBoK) Sources. A Functional Architecture is an architectural model that identifies system function and their interactions. Generally, more than one architecture can satisfy the requirements. To further the confusion, the word "Architecture" tends to be associated with either “Requirements” or “Logical” whereas "Design" tends to be associated with “Physical.” This probably stems from the fact that we, the I/S community, are starting at Row 3 and in an absolute, Enterprise sense, don’t … The functional architecture includes the system functions and the data-flows between them. ISO 5 defines logical architecture as: The logical architecture of a system is composed of a set of related technical concepts and principles that support the logical operation of the system. In computing|lang=en terms the difference between functional and logical is that functional is (computing) an object encapsulating a function pointer (or equivalent) while logical is (computing) non-physical or conceptual yet underpinned by something physical or actual. Logical Architecture vs Physical Architecture posted by John Spacey , May 30, 2017 Logical architecture is a structural design that gives as much detail as possible without constraining the architecture to a particular technology or environment.
