Systems/Box Theory Flashcards
(41 cards)
what two aspects make up scale
- temporal scale
- physical scale
two types of system feedbacks
- direct relationship
- inverse relationshihp
inverse relationship system feedback
the value of one parameter tends to decrease as the value of the other parameter in the relationship increases.
direct relationship system feedback
both variables increase together or both decrease together
is this a direct or inverse relationship
inverse
is this a direct or inverse relationship
direct
quantification
linkage of physical and conceptual models together
what can quantification ascertain
how things change
true or false
systems theory is a rational subdivision of a complex world
TRUE
true or false
systems theory stresses relationships
true
true or false
systems theory decreases the likelihood that all relevant variables are included
false
true or false
systems theory discourages quantification
false
systems theory assists with making
decision and predictions
the overall goal of natural models is to
assist in prediction
how does black box become grey box
through research
levels of the box theory
- black
- grey
- white
black box
understand inputs and outputs but NOT the interactions between or the variables
what don’t we understand with black box
the interactions between or the variables
example of a black box
we know a cow becomes a hot dog, but HOW?
grey box
understand inputs and outputs and SOME of the interactions happening
example of grey box
rainfall has lots of different interactions before it becomes run off. We understand some of those
white box
understand inputs, outputs and ALL interactions
what is important in box theory
scale
what depicts whether a system is a black, grey or white box
our understanding
