Midterm Flashcards
What is a system?
it is an interconnected set of element that is coherently organized in a way that achieves something
What is a stock?
stock are element of the system that you can see, feel, count or measure at any given time
What is a flow
it is an action that change the stock over time
what is a dynamic equilibrium
when a loop/ inflow become equal to the outflow so it level does not change can also be encounter with balancing and reinforcing feedback loop
what is a feedback loop
it is form when change in a stock affect the flow into or out of that same stock
what is a discrapency
it is the gaps btw your actual and desired level of stock
What are balancing feedback loop
they are goal seeking or stability seeking structure in system and are both source of stability and source of resistance to change
What is a reinforcing feedback loop
it enhance whatever direction of change is impose on it
what are competing balancing loop
two loop for 1 stock aiming at two diff goal
what is shifting dominance
a system is compose of several feedback loop therefore shifting dominance occur when the loop dominating the system change changing teh system behavior
Define resilience
it is a measure of a system ability to survive and persist within a variable environment. It is its ability to recover from perturbation and restore/repair itself. But there is always limits to resilience
Define self-organisation
It is the capacityof a system to make its own structure more complex. The ability to structure themselves to create new structure to learn diversify and complexify
What is hierarchie
The organization of system and sub system. Hierarchie system evolve from the buttom up. The purpose of the upper layer of the hierarchie is to serve the purpose of the lower layer
What is suboptimization
It is when a sub system goal dominate at the expense of the total system goal
what is a linear relationship
relationship btw 2 element in a system can be drawn on a graph with astraight line . It is a relationship with constant proportion
What is a nonlinear relationship
It is a relationship in which the cause do not produce a proportional effect
What is bounded rationality
Mean that people make quite reasonable decision based on the information they have. For example data could be a case of bounded rationality since your interpretation of the system is bound to this data
Identify which of carbon in the atmosphere and plant uptake is the stock and the flow
Stock : carbon
Flow : plant uptake
Identify which of barrel of water and leak in the barrel is the stock and the flow
stock= barrel of water flow= leak
Identify which of soil and erosion is the stock and the flow
stock= soil flow = erosion
