Systems Engineering

Being involved in such business activity as systems engineering, you may find the SysML Solution truly useful as it provides all the necessary tools for making your great looking systems engineering related drawings within only a very short period of time.

Systems engineering itself is a well-known interdisciplinary field of engineering as well as engineering management, focused on finding the ways to design and to manage some complex systems all over their so-called “life cycles”. As its main aim, any systems engineering activity is known to be utilizing the systems thinking principles in order to organize it.

Such issues as reliability, logistics, requirements engineering, coordination of different teams, evaluation and testing, maintainability as well as many other disciplines, which are simply necessary for successful system design, its development and its implementation become more difficult in case you have to deal with some complex or large projects.

Any systems engineering activity is known to be dealing with different work-processes, methods of optimization as well as risk management, overlapping numerous human-centred as well as technical disciplines, such as industrial engineering, manufacturing engineering, mechanical engineering, control engineering, electrical engineering, cybernetics, software engineering, project management and organizational studies. Systems engineering is known to be ensuring that all likely aspects of some system or some particular project are being taken into consideration, as well as integrated into a whole. Thus, the process of the systems engineering is simply a discovery process, known to be quite unlike any manufacturing process, which is only focused on the repetitive activities, that only achieve the high-quality outputs having minimum time and cost.

The systems engineering process usually begins by discovering some real problems which are known to be needed to get resolved, as well as identifying the most probable or simply the highest impact failures that sometimes can occur. Any systems engineering activity may involve such process as the one for finding any needed elegant solutions to the mentioned problems.

One of the ways used for understanding the motivation behind numerous systems engineering is to see it in a way of a method, or some practice, identifying as well as improving some common rules which are known to be existing within a wide variety of systems. The most commonly known principles of any systems engineering activity are holism, emergent behaviour, boundary and others.

All the mentioned principles can be applied to any of the needed systems, whether they are complex or not, employing at all levels. The companies, which deal with systems engineering, are those involved in the defence and aerospace, as well as those which are technology and information-based companies, software development ones, electronics and communications industries, known to be requiring systems engineers.

Encouraging its users to model and to simulate in order to validate theories or assumptions on systems as well as the interactions within them, systems engineering activity use the methods that allow early detection of all possible failures. In safety engineering such methods are known to be integrated into the design process.

Once the primary purpose of a systems engineer is to comprehend some complex problem, then any graphic representation of that system can be used in order to communicate that system's data as well as functional requirements. The common graphical representations may include any needed functional flow block diagram, known to be FFBD, model-based design, DFD, or Data Flow Diagram, N2 Chart, IDEF0 Diagram, Sequence diagram, Use case diagram, Signal-flow graph, Block diagram, USL Function Maps and Type Maps, Enterprise Architecture frameworks, Model-based systems engineering drawings and others.

SysML steadily gaining popularity and many companies succesfully use it in systems engeeniring. Among the tools which provides a SysML Solution, a special place occupies a wide collection of libraries - 13 libraries containing 284 vector objects:

  • SysML Activity Diagram
  • SysML Allocations
  • SysML Block Definition Diagram
  • SysML Internal Block Diagram
  • SysML Package Diagram
  • SysML Parametric Diagram
  • SysML Ports and Flows
  • SysML Profiles and Model
  • SysML Requirement Diagram
  • SysML Sequence Diagram
  • SysML State Machine Diagram
  • SysML Diagrams
  • SysML Use Case Diagram

All the mentioned drawings can be always created in ConceptDraw PRO diagramming and drawing software with help of ConceptDraw STORE application, known to be one of the best nowadays for simplifying any work with any drawing, especially with system engineering related ones in case you have SysML Solution downloaded from the mentioned product of CS Odessa.

Any graphical representation is known to be related to the numerous parts or subsystems of a system through functions, interfaces, data, etc. Any of the mentioned above methods can be used in any needed industry, which is based on its requirements. In case all the requirements are understood, then it becomes obvious that the responsibility of a systems engineer is to simply refine them. Later, he or she has to determine them with all other engineers who are known to be involved in the project in order to solve all the current issues.

Thus, systems engineering may encourage the use of the so-called weighted choices for determining the best of all the existing options. A so-called “decision matrix” can be also known as a “Pugh method”. It is one of all the possible and existing ways of making this choice if you consider all the important criteria. For example, in any SE process, the mentioned stage can represent the iterative step for carrying out until a feasible solution is eventually found. Any decision matrix is known to be populated by using special techniques: statistical analysis, system dynamics, optimization methods and reliability analysis.

Process Flowchart

When trying to figure out the nature of the problems occurring within a project, there are many ways to develop such understanding. One of the most common ways to document processes for further improvement is to draw a process flowchart, which depicts the activities of the process arranged in sequential order — this is business process management. ConceptDraw PRO is business process mapping software with impressive range of productivity features for business process management and classic project management. This business process management software is helpful for many purposes from different payment processes, or manufacturing processes to chemical processes. Business process mapping flowcharts helps clarify the actual workflow of different people engaged in the same process. This samples were made with ConceptDraw PRO — business process mapping software for flowcharting and used as classic visio alternative because its briefly named "visio for mac" and for windows, this sort of software named the business process management tools. This flowchart diagram shows a process flow of project management. The diagram that is presented here depicts the project life cycle that is basic for the most of project management methods. Breaking a project into phases allows to track it in the proper manner. Through separation on phases, the total workflow of a project is divided into some foreseeable components, thus making it easier to follow the project status. A project life cycle commonly includes: initiation, definition, design, development and implementation phases. Distinguished method to show parallel and interdependent processes, as well as project life cycle relationships. A flowchart diagram is often used as visual guide to project. For instance, it used by marketing project management software for visualizing stages of marketing activities or as project management workflow tools. Created with ConceptDraw PRO — business process mapping software which is flowcharting visio alternative or shortly its visio for mac, this sort of software platform often named the business process management process flowcharts, flowchart symbols, process flow diagram, workflow diagram, flowchart maker
