Hint
|
Answer
|
Determines if an object belongs to a system
|
|
Elements of the system
|
Objects
|
Parts of the system
|
Static viewpoint
|
Basic functions performed by the parts
|
Functional viewpoint
|
Four parts of a Control System
|
Control Object, detector, comparator, effector
|
Three types of objects
|
Inputs, processes, outputs
|
Three types of inputs
|
Serial, probable, feedback
|
Three types of outputs
|
Consumed by other systems, consumed by focal system, waste
|
Three types of relationships
|
Symbiotic, synergistic, redundant
|
Two types of attributes
|
Defining, accompanying
|
Three degrees of change
|
Stable, dynamic, turbulent
|
Output of prior system becomes input
|
Serial
|
Output from multiple prior systems is selected
|
Probable
|
Input came from current system
|
Feedback
|
Current system
|
Focal system
|
Result of systems operations
|
|
Purpose for which systems exist
|
Output
|
Bonds between objects
|
Relationships
|
Systems cannot function alone
|
Symbiotic
|
Systems work together at higher efficiency
|
|
Duplicate existing systems as a backup
|
Redundant
|
Properties of both objects and relationships which show qualitative features
|
Attributes
|
Essential to the identity of the object or relationship
|
Defining
|
Not essential towards identity of object or relationship
|
Accompanying
|
Outside focal system, not controllable by focal system
|
Environment
|
West Churchman's environmental determination Question 1
|
Is the factor system relevant?
|
West Churchman's environmental determination Question 2
|
Is the factor system controllable?
|
Implies the ability to make an object do as you desire
|
Control
|
Ability to exert pressure on decision-makers without guaranteed results
|
Influence
|
