System Engineering:
System engineering decoration, designing, implementation, validation, Deploying and maintaining social and technological systems. System engineers are not the only software that also deals with hardware and system interaction.
And its environment. Thinking about providing its services Constraints nest article is required to make and operate the system quote and is due in the next article. To complete the system change. As software engineers need, what is discussed. Understanding System Engineering Because Software Engineering Has Problems, Often the result of system engineering decisions (Thayer, 1997; Thayer, 2002).
1. The limited scope of rework during system development Once some system engineering decisions, such as setting up base stations in mobile phone systems,
Made, it's too expensive to replace them. Re-working the system design
It is rarely possible to solve these problems. One of the reasons is because the software is so, The important thing in the system is that it allows changes to occur during system development in response to new needs.
2. There are many disciplines of interdisciplinary engineering that can be covered
In system engineering. There is a lot of misunderstanding because
Different engineers use different terms and conventions.
System engineering is an interdisciplinary activity involving teams
Different background systems engineering teams are needed because extensive knowledge is needed to consider all the implications of system design decisions. As one
As an example, Figure 2.3 shows some articles that can be included
Who uses the Air Traffic Control (ATC) system for the engineering system engineering team
Radar and other sensors to determine the position of the aircraft. For many systems, there are almost unlimited possibilities between trade and trade
Different types of subsystems. Various fields are discussed to decide how functionality should be provided. There is often no 'right' decision about the system
Should swallow. Rather, you can have many possible alternatives, but you
May not be able to choose the best technical solution. Say an alternative in the air
The traffic control system aims to build new radars instead of improving existing ones.
If the civil engineers involved in the process don't have much work to do, they will
This may be in favor of the alternative because it allows them to retain their job. They can
Then argue this argument with technical arguments.
Needs/requirements of system engineering:
System requirements definitions describe what the system should do (its functions).
And its essential and required system characteristics. As software requirements analysis involves consulting with system users and end-users to create system requirements definitions. This usually requires the definition phase. Focuses on getting three types of needs:
1. Summary Functional Requirements: The basic functions that the system should provide are described at the abstract level. Details of the more detailed operational requirements are at the subsystem level. For example, in air traffic control
The system will require an abstract function to specify that the flight plan database
All aircraft entering the control should be used to store flight plans
Airspace, However, you generally won't specify the database details
Unless they affect the needs of other subsystems.
2. System Features: These are the features of a non-working system
As to availability, efficiency, and safety, as we have described above. These inactive features of the system affect the needs of all subsystems.
3. Features that the system does not want to display:
It is sometimes as important
Explain what the system should not do because it describes what the system should do.
For example, if you are defining an air traffic control system, you can specify that the system does not present the controller with much information. An important part of the requirements definition phase is to set a set. The system should meet the overall objectives. It should not be necessary
This is expressed in terms of system performance but should explain why the system is there
Shopping is being done for a specific environment Buying for a particular environment.
To illustrate what this means, say that you are providing a system for fire and protection for an office building and for detecting an intruder. A description of the system's performance-based objectives can be:
Providing a fire and intruder alarm system for the building that will provide internal and external warning of fire or unauthorized interference.
The purpose clearly states that there needs to be an alarm system that alerts you about unexpected events. Such a statement might be appropriate if you
Existing alarms were replacing the system. On the contrary, a broad set of objectives can be:
To make sure the building has a normal working schedule
Events like fire and unauthorized intervention do not seriously interfere.
If you set such a goal, you broaden and narrow the design choices.
For example, it is allowed to protect intruders using sophisticated locking technology without any internal alarms. It can also eliminate the use of sprayers for fire protection as they can affect the building's electrical system.
And so seriously manage the work.
Software engineering Modeling and Design
1- System Modeling:
The system has to be functional, Provided by system components. The activities involved are:
1. Distribution Requirements Analyze and manage:
your needs Related Groups There are usually several distribution options, and you
There are several alternatives that can be suggested at this stage of the process.
2. Identify subsystems:
You should identify subsystems that are individually or
Meet the needs collectively. The groups of needs are usually related
In the subsystem, it is possible to have this activity and distribution of requirements together. However, the identity of the subsystem may also be influenced by other organizational or environmental factors.

3. Assign Requirements to the Subsystem:
You assign the requirements to the subsystem. In principle, this should be straightforward if splitting requirements are used to run subsystem IDs. In practice, it never happens. A clear match between the distribution of requirements and the identified subsystem. The limitations of an external purchasing subsystem may mean that you have to change the requirements to accommodate these constraints. sub. Define subsystem functionality You should describe the specific functions provided by each subsystem. This can be seen as this tutorial in further articles. I'll explain these related education materials on my site www.knowledgehu92.info
4. Define subsystem functionality: You should specify the specific functions provided by each subsystem. This can be seen as part of the system design phase Define the functionality of a subsystem You should describe the specific functions provided by each subsystem. This can be seen as part of the system design phase or, if the subsystem is a software system, specifying the requirements of the system is part of the activity. You should also try to identify the relationship between them At this stage the subsystem.
5. Define the subsystem interface:
You define the provided interface and
Required by each subsystem. Once these interfaces have been agreed, this
In parallel, the development of these subsystems is possible.
