Background
Prisons Overcrowding in Saudi Arabia“some cell was 5 metres by 6 metres, and it had 23 cellmates”

main causes of overcrowding
Prisoners classification
![Page 5: Improving Prisoner Management Process Using Simulation Modeling 3/10/2014](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649e195503460f94b06b1f/html5/thumbnails/5.jpg)
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
![Page 9: Improving Prisoner Management Process Using Simulation Modeling 3/10/2014](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649e195503460f94b06b1f/html5/thumbnails/9.jpg)
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

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) .
