In winkelwagenWhat happens when a stock has two goal-seeking balancing feedback loops?
One of the feedback loops will dominate the other.
input text value
Why can information delivered by a feedback loop only affect future behavior?
Because it can't deliver a signal fast enough to correct behavior that drove the current feedback.
input text value
Why can't a flow instant react to a flow?
It can only react to a change in a stock and only after a slight delay to register the incoming information.
input text value
Why must a stock-maintaining balancing feedback loop have its goal set appropriately?
To compensate for draining or inflowing processes that affect that stock. Otherwise, the feedback process will fall short of or exceed the target for the stock.
input text value
What happens when a reinforcing and balancing loop are pulling on the same stock?
The loop that has the highest flow will dominate the system.
input text value
Complex behaviors of systems often arise as the relative strengths of feedback loops shift, causing what?
The fist one loop and then the other to dominate behavior.
The system does not behave the same constantly, but changes between different kind of feedback loops.
input text value
A delay in a balancing feedback loop makes a system likely to oscillate. That is oscillation?
They all move back and forth.
This is made resilient by giving factor a different driver so they will not show the same behavior at the same time.
input text value
What are questions for testing the value of a model?
1. Are the driving factors likely to unfold this way?
2. If they did, would the system react this way?
3. What is driving the driving factor?

1. Are the driving factors likely to unfold this way?Two stocks can be used in a system. System dynamics models explore possible futures and ask 'what if' questions. Where depends model utility on?
Why must in physical, exponentially growing systems, there always be one reinforcing loop driving the growth and at least one balancing loop constraining the growth?
Why are nonrenewable resources stock-limited?
Why are renewable resources flow-limited?
A renewable stock can be constrained by a nonrenewable stock (oil company). Why?
What is the limits-to-growth archetype?
Why are the limits on a growing system temporary or permanent?
A renewable stock can be constrained by a renewable stock (fishing company), why?
What are the 3 sets of possible behaviors with regard to renewable resource systems?
On which two factors depends the outcome of the renewable system?
What happens is the feedback is fast enough to stop capital growth before the critical threshold is reached?
What happens is the balancing feedback is slower and less effective?
What happens if the balancing loop is very weak so that capital can go on growing even as the resource is reduced below its threshold ability to regenerate itself?
Werkt prima, gelijk downloaden en geen ingewikkelde procedures. Heel fijn!
Handig te gebruiken bij het leren en er is veel aanbod op de website.
Knoowy is een zeer goed platform voor samenvattingen en ik zou het aanraden.
Ik raad Knoowy iedereen aan, die extra hulp nodig hebben bij hun opdrachten!
De documenten zijn duidelijk en goed samengevat. Het is fijner leren dan vanuit het boek.
Uitgebreid aanbod en zeer gebruiksvriendelijk! Al meerdere malen gebruik gemaakt en zoals steeds tevreden.
Tijdens mijn studie aan de Arteveldehogeschool en KU Leuven heb ik opdrachten gemaakt die ik nu via Knoowy deel met andere studenten.
Grote hulp voor het nakijken van taken! Zeker wanneer je in tijdsnood zit of niet zeker bent van je stuk.
