Unit 1 Flashcards
what term stems from the Greek work “systema”?
system
it means “an organized whole”
systema
according to Merriam Webster, this refers to a regularly interacting or interdependent group of items forming a unified whole
system
according to MIL-STD 499, it is a composite of collection of equipment, skills, and techniques capable of performing and/or supporting operational roles
system
according to International Council of Systems Engineering, it is a construct of collection of different elements (people, hardware, software, facilities, etc.) that together produce results; a self-sufficient unit
system
what is the meaning of system in simpler terms?
a system constitutes a set of interrelated components working together with the common objective of fulfilling some designated need
what are the general characteristics of a system?
- complex combinations of resources
- is contained within a hierarchy
- can be broken down into subsystems
- must have a purpose
- must respond to a functional need
what are the 4 classification of system?
- natural and man-made systems
- physical and conceptual systems
- static and dynamic systems
- closed and open-loop systems
this system came into being through natural processes like river and energy system
natural systems
this system have been developed by human beings like hydroelectric power system
man-made systems
this system is made up of real components that occupies space
physical system
this system is a series of abstract concepts, organization of ideas, specifications and plans
conceptual system
this system have structure but without activity like highways and warehouses
static system
this system combines structural components with activity like production system combined with manufacturing facility
dynamic system
this system is relatively self-contained and does not significantly interact with its environment like chemical equilibrium process and an electrical circuit
closed system
this system interacts with their environment like support capability
open system
what is the collection of component systems that produce results unachievable by individual systems alone
system of systems (SOS)
what are the 4 elements of system?
components
attributes
relationships
state
what is the element of which the system is composed? also referred to as part of the system
components
this is the properties of the individual components which characterize the system
attributes
this refers as between (pairs of) components so that the components interact to support the system’s functionality (common purpose)
relationships
this refers to the values of the attributes and relationships at a particular moment
state
TRUE OR FALSE.
A component have an effect on the properties and behavior of the system as a whole
true
TRUE OR FALSE.
A component do not depend on the properties and behavior of at least one other component in the set
false
different type of components
- structural = static
- operating = dynamic (do the work”)
- flow = changes (e.g. info, energy, material)
what are the attributes of components?
- color, strength, size, weight, power
- network topology
- max speed, machine on/off
- volume of fuel
TRUE OR FALSE.
In hierarchy, a smaller system is known as the subsytem
true
this is anything outside the system of the boundaries of the system
environment
from the environment to system
input
from system to environment
output
input, processed by system, output
throughput (transformation process)
what is the interdisciplinary approach and means to enable the realization of successful systems (INCOSE)?
systems engineering
according to IEEE (1994), it is an interdisciplinary collaborative approach to derive, evolve, and very a life cycle balanced system solution which satisfies customer expectations and meets public acceptability
systems engineering
what are the 7 current environmental challenges?
- extended system life-cycles- shorter technology life cycles
- Greater emphasis of commercial off-the-shelf (COTS) products and hardware software intellectual property (IP)
- Increasing globalization
- Greater international competition
- More outsourcing
- eroding industrial base
- higher overall life-cycle costs
