Q

this system interacts with their environment like support capability

A

17
Q

what is the collection of component systems that produce results unachievable by individual systems alone

A

system of systems (SOS)

18
Q

what are the 4 elements of system?

A

components
attributes
relationships
state

19
Q

what is the element of which the system is composed? also referred to as part of the system

A

components

20
Q

this is the properties of the individual components which characterize the system

A

attributes

21
Q

this refers as between (pairs of) components so that the components interact to support the system’s functionality (common purpose)

A

relationships

22
Q

this refers to the values of the attributes and relationships at a particular moment

A

state

23
Q

TRUE OR FALSE.

A component have an effect on the properties and behavior of the system as a whole

A

true

24
Q

TRUE OR FALSE.

A component do not depend on the properties and behavior of at least one other component in the set

A

false

25
Q

different type of components

A
  1. structural = static
  2. operating = dynamic (do the work”)
  3. flow = changes (e.g. info, energy, material)
26
Q

what are the attributes of components?

A
  1. color, strength, size, weight, power
  2. network topology
  3. max speed, machine on/off
  4. volume of fuel
27
Q

TRUE OR FALSE.

In hierarchy, a smaller system is known as the subsytem

A

true

28
Q

this is anything outside the system of the boundaries of the system

A

environment

29
Q

from the environment to system

A

input

30
Q

from system to environment

A

output

31
Q

input, processed by system, output

A

throughput (transformation process)

32
Q

what is the interdisciplinary approach and means to enable the realization of successful systems (INCOSE)?

A

systems engineering

33
Q

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

A

systems engineering

34
Q

what are the 7 current environmental challenges?

A
  1. extended system life-cycles- shorter technology life cycles
  2. Greater emphasis of commercial off-the-shelf (COTS) products and hardware software intellectual property (IP)
  3. Increasing globalization
  4. Greater international competition
  5. More outsourcing
  6. eroding industrial base
  7. higher overall life-cycle costs
