Systems Engineering Flashcards
It refers to a specific or discrete action that is necessary to achieve a given objective
Function
The first and most important phase of the system design and development process
Conceptual Design Phase
It is one that does not interact significantly with its environment
Closed System
It is a fundamental principle that the whole entities exhibit properties which are meaningful only when attributed to the entity as a whole, not to its parts
Emergence
Everything that remain outside the boundaries of the system
Environment
This model starts with user needs on the upper left and ends with a user-validated system on the upper right
VEE Process Model
It helps to ensure the elements of the system fit together to accomplish the objectives of the whole, and ultimately satisfy the needs of the customers and other stakeholders who will acquire and use the system
Systems Engineer
The degree to which a system’s design or code is difficult to understand becuase of numerous components or relationships among components
Complexity
Introduced by Royce in 1970, initially for software development
Waterfall Process Model
These are the parts of a system
Components
A structured process or mechanism for determining customer requirements and translating them into relevant technical requirements that each functional area and organization level can understand and act upon
Quality Function Deployment
It should performed with the objective of translating abroadly defined “want” into a more specific system-level requirement
Need/Need Analysis
An iterative process model that focuses on prototyping and a risk driven approach for development of products or system
Spiral Process Model
Systems from the greek word systema, meaning an ________
Organized Whole
A system component that are the parts that perform the processing
Operating Components
It is also known as advance development
Preliminary Design Phase
This is the characteristics of design and installation that reflects the ease, accuracy, safety and economy of performing maintenance actions
Maintainability
It is a combination of interacting elements organized to achieve one or more stated purposes
Engineered System
A system operational requirement that focuses on the anticipated time that the system will be in operational use
Operational Life Cycle
- The system’s engineering process generally commences with tha identification of a ________ or _________ for something based on some real deficiency
Want, Desire
- May include a combination of contractor and customer(or ultimate user) activities
Utilization Phase
They introduces “Vee” Process Model
Forsberg and Mooz
It is a systematic approach to creating a system design that simultaneously considers all phases of the life cycle, from conception through disposal
Concurrent Engineering
It is defined as “the probability that a system or product will perform in a satisfactory manner for a given period of time used under specified operating conditions
Realibility
A reliability allocation technique that is a straightforward method that assigns equal reliability requirements for all subsystems based on the system requirements
Equal Apportionment Technique
Analysis that should be performed with the objective of translating a broadly defined “want” into a more specific system-level requirement
Need Analysis
A system which human-beings have intervened through components, attributes, and relaionships
Human-Made System
This technique is a straightforward method that assigns equal reliability requirements for all subsystem based on system requirements
Equal Apportionment Technique
A structured process or mechanism for determining customer requirements and translating them into relevant technical requirements that each functional area and organization level can understand and act upon
Quality Function Demand
May include both the customer and the producer
Acquisition Phase
At whatever level in the hierarchy, consist of an components, attributes, and relationships needed to accomplish one or more objectives
Total System
Material, Energy and Information that pass from the system to the environment
Output
An Iterative process of breaking requirements down from the system level to the subsystem, and as far down the hierarchical structure as necessary to identify input design criteria and/or constraints for the various elements of the system
Functional Analysis
- A systems that are treated as a special form of engineered system
SOCIO-TECHNICAL SYSTEMS
