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) .
