By Aubra Warner and John Anderson
The Justice System
Elements:
• Population
• Economy
• Law enforcement
• Criminals
• Courts
• Prisons
Interconnections:
•Crime
•Money
Purpose:
• Reduce crime
• Improving civil order
• Stability in the prison system
Stock and Flow Model of the Justice System:
Monitoring the Prison Population in Washington State 2010
Graph Breakdown:
The graph shows that over a
period of sixty years, assuming
the values stay the same, the
population of the prisons in
Washington State would
decrease.
Values of the model:
Prison Population – 5949500 {people}
New Prisoners – Prison_Population*Crime_Rate*Repeat_Offender {people}
Released Prisoners – Prison_Population/Average_Sentence/Early_Release
{People}
Repeat offenders – 0.575 {people/month}
Crime Rate – 39.8/Population {people}
Population – 6724540 {People}
Average Sentence – 42 {month}
Early Release – 0.6 {people}
The Feedback loops within the Justice system
As prisoner population increases, early release increases, release of
prisoners increase and prison population decreases.
The Feedback loops within the Justice system
As prison population increases, early release increases, repeat offenders
increases, new prisoners increase making prison population increase.
Shocks to the System and Surprises
from the clouds
Shock to the system is economic downturn leading to higher
unemployment rate, which increases the crime rate to 4.1 per
thousand Washingtonians, which results in more people headed to
prison. The system handles it by reducing the average sentence length
and promoting early release (balancing feedback loop), which keeps
the stock (prison population) stable
Surprises from clouds could be a mass immigration of prisoners from
other states, or increased sentence length from surrounding states, or
a combination of both as well as a worldwide economic downturn,
which would affect flows because in reality, the world is a big
continuum with no real boundaries.
