System engineering (or system Design engineering, S.A. operation Research) is to be developed an interdisciplinary beginning over successfully systems and realized. In the center here on the one hand, the customer's requests, and/or desired functionalities are located to let flow early into the development cycle and on the other hand to accomplish Design synthesis and system inspection and to consider in particular the entire problem (enterprise, costs, schedule, performance, further training and support, test, production and recycling).

System engineering integrated all these engineer disciplines and abilities into a uniform, team-oriented, structured process. This process is used here by the conception over production up to the enterprise and in some cases up to the dismantling and/or for recycling. System engineering is responsible to integrate all those functions which are carried out by firmexternal specialists, since it does not appear necessary to employ such specialists vollzeitig.

Ideal way considers system engineering technical and economic necessities for all customers with the goal of handing to the customer over a product which meets its conceptions. In practice are often the customer's requests, the price and the schedule only with difficulty compatible. A task is it therefore, the borders for the costs, schedule and producibleness to determining Inc. eye: System engineering: '' BoK '' May 2006

System engineering is based on the fact that a system is more than the sum of its subsystems and/or parts not to also regard thus is it meaningfully these separately. Therefore system engineering was traditional the task of the project manager, who is responsible for the co-ordination of these large complex projects. It became in the English-language area a synonym for the development of the whole product (hardware, software, service) and additionally necessary systems (e.g. the test system or the machine to production of the product). This role became last by the people computer interaction (MCI) and the recycling supplemented.

The systems engineer needed, there hardware is occupied an engineer (more or less) with the hardware and software an engineer (more or less) with the software and this therefore little time to have and/or them the qualifications be missing to be occupied over intensively with the optimized executability of the software on the hardware or that the whole system with its elements as well as possible with its environment, in particular the user, interacted and/or whether it can being used like planned.

In order the whole system to describe to be able is it importantly constant methods for development and analysis on system and software level to be found. A possibility exists in the use of SysML, which was developed on that the basis by UML around complex systems to develop and to control be able.

The whole is more than the sum of its parts. (Aristoteles, (384-322 v. Chr.))

Overview

These methods and applications are developed and used often by "„system Engineers "“, as also in the natural sciences:

• Concept, simulation and evaluation;
• Fault trees, error analysis, FMEA
• Planning, draft, analysis, integration and enterprise of complex technical systems;
• Environmentalfair reprocessing or removal of systems;
• Interface specification and/or - development;
• Communication protocol development and specification;
• Requirement management and requirement analysis
• Verification and Validation

History

The first important employment of "„system engineering "“took place in the Telefonie. The different parts of the telecommunication system must interact very well (dt. to co-operate). A very good overview of the interfaces and logic components and their history offers "“digitally Telephony"” from John C. to Ballamy. Additional information to this topic e.g. offers Newton's Telecom Dictionary. It became stronger after that 2. World war assigned. In space travel it was used intensively after the misses around Europe rockets. To the misses it came, since the different stages without common co-ordination were developed and these were thus not one on the other co-ordinated. Therefore by the Frenchmen with the development of the Ariane rocket of system engineering was used intensively, which finally led to a large success of the rocket. Since then it is to be used in space travel standard of system engineering engineers. Since short of system engineering is used by ever more complex becoming airplanes also in the aircraft construction.

Area of application

Recently the industry accepts that developing from large and small systems can lead to new system information. Decisions at the beginning of a project, whose effects are not yet completely understood, can lead to enormous effects at the end of the project, and it is a task of modern system engineer to find these effects and make critical decisions. There is no method, which guarantees that a decision made today is still valid, if a system goes after years or decades into maintenance, but there are techniques to support the process "„of the system engineering "“. Examples of the use of simple system method teachings are Jay WRIGHT Forrester's "„system Dynamics "“methods and the Unified Modeling LANGUAGE (UML), which is constantly continued to develop, in order to support "„the engineering Process "“.

"„System engineering "“often contains the modelling and simulation of parts of the accepted system, in order to evaluate the acceptance or develop the theories further. For example high-complex systems are modelled and simulated such as airplanes before the flight. This kind of the initials model development and equation regulation can be developed, before the system exists physically. The expensive and difficult elimination of errors simplifies and reduces the risk of a crash. Careful initial testing and the advancement of the airplanes are to be developed necessarily around a safe and progressive airplane. "„System Engineers "“test and confirm the behavior of the developed system. For example with medical machines, like heart or lung machines, they examine a cooperating of the different parts of different companies. They test for example whether the loss of a part of the system can harm the patient, in order to strengthen or eliminate such a weak point. Another sphere of activity is at communication systems or bank software, since in these areas an error can contain large losses or an obligation injury. Tests of subsystems or the installation of auxiliary test functions can often eliminate errors, which would stop otherwise to the enterprise expensively.
