When identifying potential elements, a … Where the interactions are more intense (for example, where continuous information is to be exchanged with other systems), these will have to be recognized as part of a system of systemssystem of systems context and will instead be considered as part of an enterprise systems engineeringenterprise systems engineering approach. Few systems come into existence or operate without interacting with others in a system contextsystem context. OMG. 2012. Depending on whether or not evolution impacts logical architecturelogical architecture model elements, allocations to system elements may change. A physical architecturephysical architecture model is an arrangement of physical elements, (system elementssystem elements and physical interfacesphysical interfaces) that provides the solution for a productproduct, serviceservice, or enterpriseenterprise. Systems and Software Engineering -- System Life Cycle Processes. In essence, a functional architecture is a more holistic view of all factors needed to assemble a functional system. functional decomposition. The best way to do this is to produce several candidate physical architecture models, assess and compare them, and then select the most suitable one. Hoboken, NJ, USA: John Wiley and Sons, Inc, ISBN: 978-1-118-99940-0. Other analyses and assessments require knowledge and skills from the different involved technologies and specialties (mechanics, electronics, software, thermodynamics, electro-magnetic compatibility, safety, security etc.). Either they exist and can be reused or re-purposed, or they can be developed and technically implemented. 2006. The preferred physical architecture model represents the selection of system elements, their physical relationships, and interfaces. Other examples exist in most fields of engineering from nuts and bolts, plumbing, electrical installations, rail gauges, TCP/IP, IT systems and software to modular defense and space systems. ISO/IEC/IEEE 15288:2015. 2015. 1-8. There may be many (physical) ways to establish functions but fewer ways of satisfying non-functional requirements. Adjective (en adjective) In good working order.

They are performed through corresponding specialist analysis of the system. Verify that system requirements are satisfied and that the solution is realistic. For defining controllable architectures, system elements have to be grouped into higher-level system elements known as system element groups, often called sub-systems in industry. The overall Technical Baseline rolls up into the APB and consists of the following configuration baselines:. Thome, B. If a System-of-Interest is intended to be used in one or more service systemsservice systems or system of systemssystem of systems configurations, this will affect its physical architecture model. Constitute several different system element groups corresponding to different combinations of elementary system elements. If the defined element complies with a requirement, the design property will relate to (or may equal) the requirement. Restrict the number of interactions between the system elements and consider the modularity principle (maximum of consistency inside the system element, minimum of physical interfaces with outside) as the right way for architecting systems. At a high level of abstraction of multidisciplinary systems, directly allocating the functions onto technologies of the lowest level of abstraction, such as hardware or software, does not reflect a system comprehension. elements have low interdependence), Resilience (i.e. Architects and/or designers identify these capabilities from requirements and deduce corresponding quantitative or qualitative design properties to properly equip their physical architecture model (e.g., reliability, availability, maintainability, modularity, robustness, operability, climatic environment resistance, dimensions limits, etc.). ), architecture frameworksarchitecture frameworks may provide descriptions that can help to trade-off candidate architectures. One set of system element groups plus one or several non-decomposable system elements forms a candidate physical architecture model of the considered system. TOGAF, version 9.1. Some proven practices gathered from the references are provided in Table 4. Geneva, Switzerland: International Organisation for Standardisation (ISO) /International Electrotechnical Commissions (IEC)/ Institute of Electrical and Electronics Engineers (IEEE). Modeling techniques may be: Depending on the type of domain for which it is to be used (defense, enterprise, etc. Unlike these, however, logical architecture is quite broad in scope. • Derived work products, such as tables and matrices, may be used to manage these relationships and ensure coverage and traceability. Represent the synthesized physical architecture of the considered system built from system element groups, non-decomposable systems, and physical interfaces inherited from the physical architecture model of system element groups. For example, today’s video, hi-fi, and computer systems have all benefited from adoption of interface standards. The architecture is rooted on F1 that corresponds to the global control-command function.
