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: TypeCapacityAVG Daily NumberAVG Length of Stay Drugs21024 years Family Cases42521 years Financial Crimes45032 years Murder Cases1200.2(1 every 5 days)7 years Theft48042 years Waiting50113 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).
