95-462: Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design, integrate, and manage complex systems over their life cycles . At its core, systems engineering utilizes systems thinking principles to organize this body of knowledge . The individual outcome of such efforts, an engineered system , can be defined as a combination of components that work in synergy to collectively perform
190-399: A system is in the field of systems engineering. Below are a few authoritative definitions: Systems engineering processes encompass all creative, manual, and technical activities necessary to define the product and which need to be carried out to convert a system definition to a sufficiently detailed system design specification for product manufacture and deployment. Design and development of

This has happened in painting (with cubism ), physics, poetry, communication and educational theory . According to Marshall McLuhan , this paradigm shift was due to the passage from an era shaped by mechanization , which brought sequentiality, to the era shaped by the instant speed of electricity, which brought simultaneity. An article in
380-425: A Joint Cognitive System (JCS) has in particular become widely used as a way of understanding how complex socio-technical systems can be described with varying degrees of resolution. The more than 20 years of experience with CSE has been described extensively. Like systems engineering, configuration management as practiced in the defense and aerospace industry is a broad systems-level practice. The field parallels

Depending on their application, although there are several models that are used in the industry, all of them aim to identify the relation between the various stages mentioned above and incorporate feedback. Examples of such models include the Waterfall model and the VEE model (also called
570-475: A better comprehension of the design and developmental control of engineering systems as they grow more complex. Popular tools that are often used in the systems engineering context were developed during these times, including USL , UML , QFD , and IDEF . In 1990, a professional society for systems engineering, the National Council on Systems Engineering (NCOSE), was founded by representatives from
665-440: A branch of engineering in the classical sense, that is, as applied only to physical systems, such as spacecraft and aircraft. More recently, systems engineering has evolved to take on a broader meaning especially when humans were seen as an essential component of a system. Peter Checkland , for example, captures the broader meaning of systems engineering by stating that 'engineering' "can be read in its general sense; you can engineer
760-453: A broad range of complex systems. Lifecycle Modeling Language (LML), is an open-standard modeling language designed for systems engineering that supports the full lifecycle: conceptual, utilization, support, and retirement stages. Many related fields may be considered tightly coupled to systems engineering. The following areas have contributed to the development of systems engineering as a distinct entity: Cognitive systems engineering (CSE)
855-422: A collection of separate models is needed to provide all of these outcome variables. The heart of any mathematical model is a set of meaningful quantitative relationships among its inputs and outputs. These relationships can be as simple as adding up constituent quantities to obtain a total, or as complex as a set of differential equations describing the trajectory of a spacecraft in a gravitational field . Ideally,

For example, interdisciplinary faculty are usually recruited to a joint appointment , with responsibilities in both an interdisciplinary program (such as women's studies ) and a traditional discipline (such as history ). If
1045-475: A common task. The epidemiology of HIV/AIDS or global warming requires understanding of diverse disciplines to solve complex problems. Interdisciplinary may be applied where the subject is felt to have been neglected or even misrepresented in the traditional disciplinary structure of research institutions, for example, women's studies or ethnic area studies. Interdisciplinarity can likewise be applied to complex subjects that can only be understood by combining

Interdisciplinary programs sometimes arise from a shared conviction that the traditional disciplines are unable or unwilling to address an important problem. For example, social science disciplines such as anthropology and sociology paid little attention to
1235-564: A discipline in engineering. The aim of education in systems engineering is to formalize various approaches simply and in doing so, identify new methods and research opportunities similar to that which occurs in other fields of engineering. As an approach, systems engineering is holistic and interdisciplinary in flavor. The traditional scope of engineering embraces the conception, design, development, production, and operation of physical systems. Systems engineering, as originally conceived, falls within this scope. "Systems engineering", in this sense of
1330-455: A job. At this point starting with a trade study, systems engineering encourages the use of weighted choices to determine the best option. A decision matrix , or Pugh method, is one way ( QFD is another) to make this choice while considering all criteria that are important. The trade study in turn informs the design, which again affects graphic representations of the system (without changing the requirements). In an SE process, this stage represents
1425-511: A meeting or a political agreement." Consistent with the broader scope of systems engineering, the Systems Engineering Body of Knowledge (SEBoK) has defined three types of systems engineering: Systems engineering focuses on analyzing and eliciting customer needs and required functionality early in the development cycle , documenting requirements, then proceeding with design synthesis and system validation while considering
1520-641: A number of U.S. corporations and organizations. NCOSE was created to address the need for improvements in systems engineering practices and education. As a result of growing involvement from systems engineers outside of the U.S., the name of the organization was changed to the International Council on Systems Engineering (INCOSE) in 1995. Schools in several countries offer graduate programs in systems engineering, and continuing education options are also available for practicing engineers. Systems engineering signifies only an approach and, more recently,
1615-437: A particular profession. These requirements are intended to encourage professionals to expand their foundations of knowledge and stay up-to-date on new developments. Depending on the field, these requirements may be satisfied through college or university coursework, extension courses or conferences and seminars attendance. Although individual professions may have different standards, the most widely accepted standard, developed by
1710-403: A process under multiple constraints. Interdisciplinary Interdisciplinarity or interdisciplinary studies involves the combination of multiple academic disciplines into one activity (e.g., a research project). It draws knowledge from several fields like sociology, anthropology, psychology, economics, etc. It is related to an interdiscipline or an interdisciplinary field, which
1805-405: A project or system are considered and integrated into a whole. The systems engineering process is a discovery process that is quite unlike a manufacturing process. A manufacturing process is focused on repetitive activities that achieve high-quality outputs with minimum cost and time. The systems engineering process must begin by discovering the real problems that need to be resolved and identifying
1900-528: A project whose consequences are not clearly understood can have enormous implications later in the life of a system, and it is the task of the modern systems engineer to explore these issues and make critical decisions. No method guarantees today's decisions will still be valid when a system goes into service years or decades after first conceived. However, there are techniques that support the process of systems engineering. Examples include soft systems methodology, Jay Wright Forrester 's System dynamics method, and
1995-658: A regularly updated directory of worldwide academic programs at suitably accredited institutions. As of 2017, it lists over 140 universities in North America offering more than 400 undergraduate and graduate programs in systems engineering. Widespread institutional acknowledgment of the field as a distinct subdiscipline is quite recent; the 2009 edition of the same publication reported the number of such schools and programs at only 80 and 165, respectively. Education in systems engineering can be taken as systems-centric or domain-centric : Both of these patterns strive to educate

Interdisciplinary research is also key to the study of health sciences, for example in studying optimal solutions to diseases. Some institutions of higher education offer accredited degree programs in Interdisciplinary Studies. At another level, interdisciplinarity

Georgetown University , Michigan State University , and the University of Denver have benefited from non-credit programs as it relates to strengthening partnerships with corporations and government agencies, helping to inform and shape
2280-435: A single disciplinary perspective (for example, women's studies or medieval studies ). More rarely, and at a more advanced level, interdisciplinarity may itself become the focus of study, in a critique of institutionalized disciplines' ways of segmenting knowledge. In contrast, studies of interdisciplinarity raise to self-consciousness questions about how interdisciplinarity works, the nature and history of disciplinarity, and
2375-551: A single program of instruction. Interdisciplinary theory takes interdisciplinary knowledge, research, or education as its main objects of study. In turn, interdisciplinary richness of any two instances of knowledge, research, or education can be ranked by weighing four variables: number of disciplines involved, the "distance" between them, the novelty of any particular combination, and their extent of integration. Interdisciplinary knowledge and research are important because: "The modern mind divides, specializes, thinks in categories:
2470-414: A system can be divided into four stages, each with different definitions: Depending on their application, tools are used for various stages of the systems engineering process: Models play important and diverse roles in systems engineering. A model can be defined in several ways, including: Together, these definitions are broad enough to encompass physical engineering models used in the verification of

This section focuses on the last. The main reason for using mathematical models and diagrams in trade studies is to provide estimates of system effectiveness, performance or technical attributes, and cost from a set of known or estimable quantities. Typically,

Issues such as requirements engineering , reliability, logistics , coordination of different teams, testing and evaluation, maintainability, and many other disciplines , aka "ilities" , necessary for successful system design , development, implementation , and ultimate decommission become more difficult when dealing with large or complex projects . Systems engineering deals with work processes, optimization methods, and risk management tools in such projects. It overlaps technical and human-centered disciplines such as industrial engineering , production systems engineering , process systems engineering , mechanical engineering , manufacturing engineering , production engineering , control engineering , software engineering , electrical engineering , cybernetics , aerospace engineering , organizational studies , civil engineering and project management . Systems engineering ensures that all likely aspects of

As such, both fields are distinguished by the scope of their projects rather than the methodology of their practice. Operations research supports systems engineering. Operations research, briefly, is concerned with the optimization of

Interface design and its specification are concerned with assuring that the pieces of a system connect and inter-operate with other parts of the system and with external systems as necessary. Interface design also includes assuring that system interfaces are able to accept new features, including mechanical, electrical, and logical interfaces, including reserved wires, plug-space, command codes, and bits in communication protocols. This

Large engineering teams are usually interdisciplinary, as a power station or mobile phone or other project requires the melding of several specialties. However, the term "interdisciplinary" is sometimes confined to academic settings. The term interdisciplinary
3325-399: Is applied within education and training pedagogies to describe studies that use methods and insights of several established disciplines or traditional fields of study. Interdisciplinarity involves researchers, students, and teachers in the goals of connecting and integrating several academic schools of thought, professions, or technologies—along with their specific perspectives—in the pursuit of
3420-529: Is best seen as bringing together distinctive components of two or more disciplines. In academic discourse, interdisciplinarity typically applies to four realms: knowledge, research, education, and theory. Interdisciplinary knowledge involves familiarity with components of two or more disciplines. Interdisciplinary research combines components of two or more disciplines in the search or creation of new knowledge, operations, or artistic expressions. Interdisciplinary education merges components of two or more disciplines in
3515-594: Is given back to the various disciplines involved. Therefore, both disciplinarians and interdisciplinarians may be seen in complementary relation to one another. Because most participants in interdisciplinary ventures were trained in traditional disciplines, they must learn to appreciate differences of perspectives and methods. For example, a discipline that places more emphasis on quantitative rigor may produce practitioners who are more scientific in their training than others; in turn, colleagues in "softer" disciplines who may associate quantitative approaches with difficulty grasp
3610-420: Is inherently complex since the behavior of and interaction among system components is not always immediately well defined or understood. Defining and characterizing such systems and subsystems and the interactions among them is one of the goals of systems engineering. In doing so, the gap that exists between informal requirements from users, operators , marketing organizations, and technical specifications
3705-513: Is known as extensibility . Human-Computer Interaction (HCI) or Human-Machine Interface (HMI) is another aspect of interface design and is a critical aspect of modern systems engineering. Systems engineering principles are applied in the design of communication protocols for local area networks and wide area networks . Mechatronic engineering , like systems engineering, is a multidisciplinary field of engineering that uses dynamic systems modeling to express tangible constructs. In that regard, it
3800-607: Is seen as a remedy to the harmful effects of excessive specialization and isolation in information silos . On some views, however, interdisciplinarity is entirely indebted to those who specialize in one field of study—that is, without specialists, interdisciplinarians would have no information and no leading experts to consult. Others place the focus of interdisciplinarity on the need to transcend disciplines, viewing excessive specialization as problematic both epistemologically and politically. When interdisciplinary collaboration or research results in new solutions to problems, much information

3990-544: Is sometimes called 'field philosophy'. Perhaps the most common complaint regarding interdisciplinary programs, by supporters and detractors alike, is the lack of synthesis—that is, students are provided with multiple disciplinary perspectives but are not given effective guidance in resolving the conflicts and achieving a coherent view of the subject. Others have argued that the very idea of synthesis or integration of disciplines presupposes questionable politico-epistemic commitments. Critics of interdisciplinary programs feel that

The principles of systems engineering – holism, emergent behavior, boundary, et al. – can be applied to any system, complex or otherwise, provided systems thinking is employed at all levels. Besides defense and aerospace, many information and technology-based companies, software development firms, and industries in the field of electronics & communications require systems engineers as part of their team. An analysis by

Education in systems engineering is often seen as an extension to the regular engineering courses, reflecting the industry attitude that engineering students need a foundational background in one of the traditional engineering disciplines (e.g. aerospace engineering , civil engineering , electrical engineering , mechanical engineering , manufacturing engineering , industrial engineering , chemical engineering )—plus practical, real-world experience to be effective as systems engineers. Undergraduate university programs explicitly in systems engineering are growing in number but remain uncommon,

When it was no longer possible to rely on design evolution to improve upon a system and the existing tools were not sufficient to meet growing demands, new methods began to be developed that addressed the complexity directly. The continuing evolution of systems engineering comprises the development and identification of new methods and modeling techniques. These methods aid in
5035-420: The V model). System development often requires contribution from diverse technical disciplines. By providing a systems ( holistic ) view of the development effort, systems engineering helps mold all the technical contributors into a unified team effort, forming a structured development process that proceeds from concept to production to operation and, in some cases, to termination and disposal. In an acquisition,

For example, the subject of land use may appear differently when examined by different disciplines, for instance, biology , chemistry , economics , geography , and politics . Although "interdisciplinary" and "interdisciplinarity" are frequently viewed as twentieth century terms, the concept has historical antecedents, most notably Greek philosophy . Julie Thompson Klein attests that "the roots of

The development of smarter control algorithms , microprocessor design , and analysis of environmental systems also come within the purview of systems engineering. Systems engineering encourages the use of tools and methods to better comprehend and manage complexity in systems. Some examples of these tools can be seen here: Taking an interdisciplinary approach to engineering systems
5510-408: The ascendancy of interdisciplinary studies against traditional academia. There are many examples of when a particular idea, almost in the same period, arises in different disciplines. One case is the shift from the approach of focusing on "specialized segments of attention" (adopting one particular perspective), to the idea of "instant sensory awareness of the whole", an attention to the "total field",

An interdisciplinary program may not succeed if its members remain stuck in their disciplines (and in disciplinary attitudes). Those who lack experience in interdisciplinary collaborations may also not fully appreciate the intellectual contribution of colleagues from those disciplines. From the disciplinary perspective, however, much interdisciplinary work may be seen as "soft", lacking in rigor, or ideologically motivated; these beliefs place barriers in

For example, interdisciplinary grant applications are often refereed by peer reviewers drawn from established disciplines ; interdisciplinary researchers may experience difficulty getting funding for their research. In addition, untenured researchers know that, when they seek promotion and tenure , it is likely that some of the evaluators will lack commitment to interdisciplinarity. They may fear that making

When speaking in this context, complexity incorporates not only engineering systems but also the logical human organization of data. At the same time, a system can become more complex due to an increase in size as well as with an increase in

The term is used mainly in the United States and Canada. Recognized forms of post-secondary learning activities within the domain include: degree credit courses by non-traditional students , non-degree career training, college remediation, workforce training, and formal personal enrichment courses (both on-campus and online). General continuing education

The term systems engineering can be traced back to Bell Telephone Laboratories in the 1940s. The need to identify and manipulate the properties of a system as a whole, which in complex engineering projects may greatly differ from the sum of the parts' properties, motivated various industries, especially those developing systems for

An initial distinction should be made between interdisciplinary studies, which can be found spread across the academy today, and the study of interdisciplinarity, which involves a much smaller group of researchers. The former is instantiated in thousands of research centers across the US and the world. The latter has one US organization,

The adjective interdisciplinary is most often used in educational circles when researchers from two or more disciplines pool their approaches and modify them so that they are better suited to the problem at hand, including the case of the team-taught course where students are required to understand a given subject in terms of multiple traditional disciplines. Interdisciplinary education fosters cognitive flexibility and prepares students to tackle complex, real-world problems by integrating knowledge from multiple fields. This approach emphasizes active learning, critical thinking, and problem-solving skills, equipping students with
7505-486: The philosophy and promise of interdisciplinarity in academic programs and professional practice, social scientists are increasingly interrogating academic discourses on interdisciplinarity, as well as how interdisciplinarity actually works—and does not—in practice. Some have shown, for example, that some interdisciplinary enterprises that aim to serve society can produce deleterious outcomes for which no one can be held to account. Since 1998, there has been an ascendancy in
7600-469: The relationships express causality, not just correlation. Furthermore, key to successful systems engineering activities are also the methods with which these models are efficiently and effectively managed and used to simulate the systems. However, diverse domains often present recurring problems of modeling and simulation for systems engineering, and new advancements are aiming to cross-fertilize methods among distinct scientific and engineering communities, under

As a result, many social scientists with interests in technology have joined science, technology and society programs, which are typically staffed by scholars drawn from numerous disciplines. They may also arise from new research developments, such as nanotechnology , which cannot be addressed without combining the approaches of two or more disciplines. Examples include quantum information processing , an amalgamation of quantum physics and computer science , and bioinformatics , combining molecular biology with computer science. Sustainable development as
7980-426: The spring of 2009, Eduventures , a higher education consulting firm, released the results of a study that illustrated that the recession had made a significant impact on the views of prospective continuing education students. A survey of 1,500 adults who planned to enroll in a course or program within the next two years determined that while nearly half of respondents believed that the value of education had risen due to
8075-462: The systems engineer who is able to oversee interdisciplinary projects with the depth required of a core engineer. Systems engineering tools are strategies , procedures, and techniques that aid in performing systems engineering on a project or product . The purpose of these tools varies from database management, graphical browsing, simulation, and reasoning, to document production, neutral import/export, and more. There are many definitions of what
8170-564: The taskings of systems engineering; where systems engineering deals with requirements development, allocation to development items and verification, configuration management deals with requirements capture, traceability to the development item, and audit of development item to ensure that it has achieved the desired functionality that systems engineering and/or Test and Verification Engineering have proven out through objective testing. Control engineering and its design and implementation of control systems , used extensively in nearly every industry,
8265-401: The term, refers to the building of engineering concepts. The use of the term "systems engineer" has evolved over time to embrace a wider, more holistic concept of "systems" and of engineering processes. This evolution of the definition has been a subject of ongoing controversy, and the term continues to apply to both the narrower and a broader scope. Traditional systems engineering was seen as
8360-448: The title of 'Modeling & Simulation-based Systems Engineering'. Initially, when the primary purpose of a systems engineer is to comprehend a complex problem, graphic representations of a system are used to communicate a system's functional and data requirements. Common graphical representations include: A graphical representation relates the various subsystems or parts of a system through functions, data, or interfaces. Any or each of
8455-439: The traditional discipline makes the tenure decisions, new interdisciplinary faculty will be hesitant to commit themselves fully to interdisciplinary work. Other barriers include the generally disciplinary orientation of most scholarly journals, leading to the perception, if not the fact, that interdisciplinary research is hard to publish. In addition, since traditional budgetary practices at most universities channel resources through
8550-478: The value of interdisciplinary research and teaching and a growth in the number of bachelor's degrees awarded at U.S. universities classified as multi- or interdisciplinary studies. The number of interdisciplinary bachelor's degrees awarded annually rose from 7,000 in 1973 to 30,000 a year by 2005 according to data from the National Center of Educational Statistics (NECS). In addition, educational leaders from
8645-752: Was also a trustee of the Lowell Institute, expanded plans to offer Lowell Institute public courses directly with Harvard. In 1910, Lowell formally established the Havard Extension School , then referred to as the Commission on Extension Courses. The Harvard Extension School now operates under the Faculty of Arts and Sciences and is one of the 13 degree-granting schools that makes up Harvard University . The School has remained in continuous operation since 1910. Cornell University
8740-661: Was among higher education institutions that began offering university-based continuing education, primarily to teachers, through extension courses in the 1870s. As noted in the Cornell Era of February 16, 1877, the university offered a "Tour of the Great Lakes" program for "teachers and others" under the direction of Professor Theodore B. Comstock , head of Cornell's department of geology. The University of Wisconsin–Madison began its continuing education program in 1907. The New School for Social Research, founded in 1919,
8835-613: Was founded in 1874 "as an educational experiment in out-of-school, vacation learning. It was successful and broadened almost immediately beyond courses for Sunday school teachers to include academic subjects, music, art and physical education." Harvard University traces its origins in continuing education to 1835 when John Lowell Jr. established the Lowell Institute with a mission to provide free public lectures in Boston. In 1909, then-Harvard President A. Lawrence Lowell , who
8930-484: Was founded in 2008 but is closed as of 1 September 2014, the result of administrative decisions at the University of North Texas. An interdisciplinary study is an academic program or process seeking to synthesize broad perspectives , knowledge, skills, interconnections, and epistemology in an educational setting. Interdisciplinary programs may be founded in order to facilitate the study of subjects which have some coherence, but which cannot be adequately understood from
9025-857: Was initially devoted to adult education. In 1969, Empire State College , a unit of the State University of New York , was the first institution in the US to exclusively focus on providing higher education to adult learners. In 1976 the University of Florida created its own Division of Continuing Education and most courses were offered on evenings or weekends to accommodate the schedules of working students. The method of delivery of continuing education can include traditional types of classroom lectures and laboratories. However, many continuing education programs make heavy use of distance education , which not only includes independent study, but can also include videotaped material, broadcast programming or online education which has more recently dominated
