Systems engineering deals with design, integration and management complex systems throughout their entire life cycle. It draws on a body of knowledge that encompasses various disciplines and practices. One of the key aspects is the implementation of activities that lead to the successful development and management of these complex systems.
According to NASA Systems Engineering pursues the following goals:
A complex system consists of numerous components interact with each other, such as hardware, software and other subsystems. They all work together to achieve a set goal. Systems thinking helps engineers recognize the interdependencies and interactions within the system and take a comprehensive view.
Feedback loops influence the behavior of the system. The development of these systems is a crucial aspect of systems engineering, including production systems. The understanding of the System structure plays an important role in the effective management of these interactions. Cognitive Systems Engineering works as a method for analyzing and designing these complex systems and forms the basis of system development.
The job of a systems engineer is to evaluate and harmonize the contributions of different disciplines. His goal is one uniform result, which is not heavily influenced by any particular discipline. Systems engineers are responsible for implementing and maintaining IT systems that include hardware, software, equipment, facilities, personnel, processes and procedures.
The role of systems engineers is to manage and combine multiple disciplines to ensure the effective development and operation of a system. They must ensure that complex systems function as intended and meet the needs of stakeholders.
The term systems engineering first appeared in the 1940s at Bell Telephone Laboratories, where the concepts of systems engineering were developed. Since then, the engineering discipline has evolved, also with the help of standardization and guidelines developed by organizations such as Incose, GfSE, ISO or VDI.
These organizations provide guidelines for various types of integrated systems to ensure their effective development, integration and management.
The primary processes of systems engineering, including systems analysis, requirements elicitation and model-based systems engineering (MBSE), are closely related to the Project management. These processes include planning, executing and controlling the development of complex systems.
Early contributions to systems engineering include the development of concepts and practices at Bell Labs and the groundbreaking techniques and methods developed by engineers at the NASA and the MIT were developed and formed the basis for the discipline of systems engineering. These techniques, such as systems analysis, systems design, systems integration and systems engineering management, have been widely adopted and have contributed to the advances in systems engineering.
The impact of these early developments on the field was significant, as they provided a framework for developing complex systems and enabled engineers to design systems that met customer requirements.
Standards such as ISO/IEC/IEEE 15288, ANSI/EIA-632, ISO/IEC 26702 (formerly IEEE 1220), MIL-STD 499 Series (US military standard), IEC 62278 (formerly IEC 15288) and ISO 29148 are related to systems engineering applicable and offer a uniform framework for process descriptions in the life cycle of systems. They describe the processes and terminology of the system life cycle from a technical perspective. That is also useful Incose Systems Engineering Handbook. While it is not a formal standard, it is published by the International Council on Systems Engineering (Incose) and provides detailed guidance on best practices in systems engineering.
The aim of all these standards and guidelines is to ensure uniformity and excellence in systems engineering practices, with compliance with the standards enabling improved quality, greater efficiency and reduced costs. However, challenges associated with applying the standards include the need for training and the complexity of adapting to changing requirements.
The core processes of systems engineering include: System analysis and identifying the requirements that are essential to understanding user and stakeholder needs and defining system boundaries. The Model-Based Systems Engineering approach (MBSE) is another core process in this area that uses system models to support various processes, including customer requirements, design and verification.
System analysis and Requirements elicitation are of central importance to understand the requirements of users and stakeholders and to define the system boundaries. The process includes collecting and analyzing relevant data, identifying system requirements, and developing a comprehensive system design.
By considering these requirements, system performance can be improved, efficiency increased and costs minimized.
The Model-Based Systems Engineering (MBSE) approach uses models to represent the system and its components. It will provide structured support for development and Verification used by systems. It facilitates the collection, analysis and communication of customer requirements, design and verification.
MBSE offers the following Benefits:
However, the implementation of MBSE requires a significant time and resourceseffort, and integration into existing systems can be complex.
The integration of human systems and the socioeconomic context are critical components of systems engineering. In addition to the integration of hardware and software, this also includes human factors to be taken into account. According to NPR 7123.1, a system is defined as “The combination of elements that work together to produce the capability necessary to meet a need, including all
necessary for this purpose". In this context, understanding and consideration of human factors are essential to the success of a system.
Human factors play a crucial role in the design and development of tools, machines and systems because they take into account human capabilities, limitations and behavior. By considering users' abilities, limitations, and behaviors, system engineers can ensure that the Design has the following features:
In systems engineering, the consideration of human factors includes user needs and preferences, the study of the interaction between the user and the system, and the analysis of aspects such as usability, psychological stress and security.
The operational concept in systems engineering is a document that describes the features and operation of a proposed system from the user's perspective. The Involvement of stakeholders is essential in systems engineering because it ensures that the system meets the needs of all users and stakeholders.
During system development, stakeholders contribute their input and feedback to the design and development of the system and ensure that the system meets the needs of all users and stakeholders. Involving stakeholders in system development has the potential to improve system design, increase user satisfaction, and enable better risk management.
Cost efficiency and risk management are integral parts of systems engineering, using design trade studies and risk mitigation strategies to achieve a balance between costs and benefits. The systems engineer's dilemma refers to the difficulty of making decisions when faced with alternatives in a Design Trade Study require a compromise between cost and effectiveness.
Schedule time is often a vital resource; therefore, the schedule can be viewed as a type of cost.
A design trade study (Design Trade Study) is a formalized process of evaluating and comparing various design options to maximize cost, schedule, performance and risk. Your goal is to determine the most advantageous combination of cost and effectiveness in system development.
This process includes analyzing system requirements, evaluating design alternatives, and comparing results to determine the most cost-effective option. Design trade studies consequently lead to better system performance, cost reductions and improved risk management.
Risk mitigation strategies can be used to reduce the potential for to reduce problems and to ensure the successful operation of a system. These strategies include:
Risk reduction strategies play a crucial role in:
Advanced Systems Engineering is a field of engineering, which focuses on the development and implementation of complex systems. Innovative technologies and techniques are used to create efficient, reliable and cost-effective systems. Innovations and challenges in this area include closed-loop engineering and advanced V/V techniques.
In the Closed loop engineering is about the design and development of systems capable of monitoring and adjusting their performance based on feedback from the environment. This makes the systems more efficient and reliable. Advanced V/V techniques, such as simulation, prototyping and testing, are used to verify and confirm the effectiveness of a system. Both closed-loop engineering and advanced V/V techniques play an essential role in improving system development and operation.
A new perspective for the value creation of tomorrow is researched and designed Fraunhofer Institute for Mechatronics Design (IEM) with Advanced Systems Engineering (ASE). Future engineering networks and supports activities in science and business. The ASE brings together technologies, methods and competencies from different domains. The Fraunhofer experts explain this in the following video:
