The document discusses using business process simulation to help optimize a banking company's credit approval process. Key steps include building a process model, then running simulations to answer questions about throughput, costs, resource needs, and how the process could handle increases in loan volume. The simulation software allows parameterizing process elements and generates event data. Results are analyzed to identify performance, quality, resource utilization, and inform continuous process improvements.

1. Business Process Simulation
● Sample scenario:
– Banking company purchased your product.
– You go on-site to help implement their credit approval
process.
– For example you come up with:

2. Business Process Simulation (2)
● Sample scenario (cont.):
– Business process model is done, next step in
BPM Life-Cycle is Execution...BUT WAIT!
– Customer questions:
● How many credit approvals can we handle during a given
timeframe?
● How much will running this process cost us per month?
● How many new resources would we need to double our
throughput?
● Are we ready for winter season (loans triple)?
● What could be done to optimize this process?
– Answer: Let's use simulation to try to answer these questions
for you :)

3. Business Process Simulation (3)
● Goals:
– Statistical Analysis of process models over time
– Pre-execution and post-execution optimization
– Reducing risk of change
– Predict business process performance
– Continuous improvement
● Performance
● Quality
● Resource utilization
● Challenges:
– Increase process complexity
– Result presentation / interpretation
– Standard / Interoperability

4. ● +
– Each element of the process can be parameterized to add
simulation information
● Time
● Resource
● Cost
● Priority
● etc
BPS in jBPM - Notation

5. BPS in jBPM - Runtime
● Extension to the jBPM runtime engine
● Relies on process paths rather than process data
● Built on-top of the Drools simulation and test framework.
● Generates individual events for every simulated activity.
● Events can be stored in simulation repository
● CEP and Rules applied to provide meaningful simulation
results.

6. BPS in jBPM - Tooling
● JBPM Designer
● Simulate “as you go”
● In-line process simulation
● Visualize process paths
