Improving Prisoner Management Process Using Simulation Modeling
3/10/2014
Background
Prisons Overcrowding in Saudi Arabia“some cell was 5 metres by 6 metres, and it had 23 cellmates”
Background Cont.
main causes of overcrowding
Prisoners classification
Prisoner Classification in Saudi Arabia
• Prisoners allocations cells depends on Offences types :
Theft family cases Drugs Murder Cases Financial crime
• Why this classification causes overcrowding?
Solution to Reduce Overcrowding
Risk classification
• A : High Security
• B: Medium Security
• C: Low Security
Offences classification Drugs Murder Cases
Theft family cases
Financial Crimes
Anylogic simulation tool
Defination– AnyLogic is a multimethod simulation modeling tool developed by
The AnyLogic Company .
• Advantages :– Value. – Time. – Visibility.
Methodology
Using AnyLogic simulation tool :
• Collect Data• Establish Modeling• Create simulation• Test different scenario• Analyze results
Collect Data
The data, which is necessary to build this model, was collected from the prison general directorate as below:
Type Capacity AVG Daily Number AVG Length of Stay
Drugs 210 2 4 years
Family Cases 425 2 1 years
Financial Crimes 450 3 2 years
Murder Cases 120 0.2(1 every 5 days) 7 years
Theft 480 4 2 years
Waiting 50 11 3 days

Results Discussion
Offense Classification• Drugs cases %
299.5• Family cases %68 • Financial crimes %
123.5 • Murder cases %83.3 • Theft cases %
134.5
Risk Classification
• High Security %116.9• Medium Security %111.5• Low Security %103.8
Conclusion
• Project Scope : using a new method of prisoners classification to run through Anylogic simulation tool in one prison to get an idea of what might happen if it was put in action
• Project Aim : examine this method (if it is helpful to get a best utilize of prison capacity or not and Why) .
