Systems analysis is the interdisciplinary branch of science, dealing with analysis of systems, often prior to their automation as computer systems, and the interactions within those systems. This field is closely related to operations research. Interdisciplinary work is that which integrates concepts across different disciplines. ... A magnet levitating above a high-temperature superconductor demonstrates the Meissner effect. ... For other uses, see System (disambiguation). ... Operations Research or Operational Research (OR) is an interdisciplinary branch of mathematics which uses methods like mathematical modeling, statistics, and algorithms to arrive at optimal or good decisions in complex problems which are concerned with optimizing the maxima (profit, faster assembly line, greater crop yield, higher bandwidth, etc) or minima...



The terms analysis and synthesis come from classical Greek and mean respectively "to loosen up" and "to put together" . These terms are used in scientific disciplines from mathematics and logic to economy and psychology to denote similar investigative procedures. In general, analysis is defined as the procedure by which we break down an intellectual or substantial whole into parts or components. Synthesis is defined as the opposite procedure: to combine separate elements or components in order to form a coherent whole.[1] Look up analysis in Wiktionary, the free dictionary. ... Synthesis (from the ancient Greek σύν (with) and θεσις (placing), is commonly understood to be an integration of two or more pre-existing elements which results in a new creation. ... This is a list of academic disciplines (and academic fields). ...

The systems discussed within systems analysis can be within any field such as: industrial processes, management, decision making processes, environmental protection processes, etc. The brothers Howard T. Odum and Eugene Odum began applying a systems view to ecology in 1953, building on the work of Raymond Lindeman (1942) and Arthur Tansley (1935). For other uses, see Management (disambiguation). ... Decision making is the cognitive process of selecting a course of action from among multiple alternatives. ... Environmental movement is a term often used for any social or political movement directed towards the preservation, restoration, or enhancement of the natural environment. ... Howard Thomas Odum (1924-2002), commonly known as H.T. Odum or Tom Odum, was an eminent American ecosystem ecologist and a professor at the University of Florida. ... Eugene Pleasants Odum (1913-2002) was an American scientist known for his pioneering work on ecosystem ecology. The average schoolchild of today knows that humans (along with other life forms) depend on adequate conditions of food, water, and shelter from inclement elements, for instance, and also that weather, geological, and... For the journal, see Ecology (journal). ... Please wikify (format) this article or section as suggested in the Guide to layout and the Manual of Style. ... Sir Arthur George Tansley (1871 - 1955) was an English botanist who was a pioneer in the science of plant ecology. ...

Systems analysis researchers apply mathematical methodology to the analysis of the systems involved trying to form a detailed overall picture. Mathematics is commonly defined as the study of patterns of structure, change, and space; more informally, one might say it is the study of figures and numbers. Mathematical knowledge is constantly growing, through research and application, but mathematics itself is not usually considered a natural science. ... Meethodology is defined as the analysis of the principles of methods, rules, and postulates employed by a discipline, the systematic study of methods that are, can be, or have been applied within a discipline or a particular procedure or set of procedures [1]. It should be noted that methodology is...


Practitioners of systems analysis are often called up to dissect systems that have grown haphazardly to determine the current components of the system. This was shown during the year 2000 re-engineering effort as business and manufacturing processes were examined and simplified as part of the Y2K automation upgrades. Current employment titles utilizing systems analysis include, but are not limited to, Systems Analyst, Business Analyst, Manufacturing Engineer, Enterprise Architect, etc. Systems analysis is the science dealing with analysis of complex, large scale systems and the interactions within those systems. ... The term Business Analyst (BA) is used to describe a person who practices the discipline of business analysis. ... Industrial engineering is the engineering discipline that concerns the design, development, improvement, implementation and evaluation of integrated systems of people, knowledge, equipment, energy, and material. ... The Enterprise Architect is one who is responsible for design and management of the the end-to end Technology components (both macro and micro) and provides governance to ensure that they remain aligned to the business objectives. ...

While practitioners of systems analysis can be called upon to create entirely new systems their skills are more often used to modify, expand or document existing systems (processes, procedures and methods). Illustration of a physical process: a geyser in action. Process (lat. ... Look up Procedure in Wiktionary, the free dictionary. ... Meethodology is defined as the analysis of the principles of methods, rules, and postulates employed by a discipline, the systematic study of methods that are, can be, or have been applied within a discipline or a particular procedure or set of procedures [1]. It should be noted that methodology is...

System analysis - Wikipedia, the free encyclopedia (1121 words)
Although many of the methods of system analysis can be applied to non-electrical systems, it is a subject often studied by electrical engineers because it has direct relevance to many other areas of their discipline, most notably signal processing and communication systems.
A system that is not linear is non-linear.
A lumped LTI system is specified by a finite number of parameters, be it the zeros and poles of its transfer function, or the coefficients of its differential equation, whereas specification of a distributed LTI system requires a complete functional description of its transfer function.
