• How long does an analysis take?
• When to use which method?
• How do I know I’m right?
• Is the last question important?

Hubert Klüpfel20TraffGoGo HT
When to use which method
• Simplified Method – Calculation– For small ships– If you won’t do it again
• Advanced Method – Simulation – Complex scenarios– If you’re doing it repeatedly
![Page 21: Hubert Klüpfel1 Go Traff Go HT Understanding the Impact of Regulatory Changes](https://reader036.vdocuments.us/reader036/viewer/2022062318/551b5d2d5503465c7e8b60a8/html5/thumbnails/21.jpg)
Hubert Klüpfel21TraffGoGo HT
How to learn it?
• Simplified Method – Calculation– Detailed knowledge of the method’s rationale– Patience and strictness
• Advanced Method – Simulation – How to handle the simulation program– What model is the simulation based on
(if you want)
![Page 22: Hubert Klüpfel1 Go Traff Go HT Understanding the Impact of Regulatory Changes](https://reader036.vdocuments.us/reader036/viewer/2022062318/551b5d2d5503465c7e8b60a8/html5/thumbnails/22.jpg)
Hubert Klüpfel22TraffGoGo HT
Comparison of the Efforts
• Simplified Method – Calculation– Can be done with paper and pencil– Same effort for each new scenario / each
repetition
• Advanced Method – Simulation – You need a computer simulation– Repetition is cheap

Current reaction span is too big.
response time variance = 1,5 min
response time variance = 3 min
(advanced: 6 min)
response time variance = 0 min

Refining Definitions
• Significant Congestion
• Reduced Escape Route Availability
• Simplify Tables (e.g. Demographic Parameters)
• Counterflow
• Passenger & Crew Distribution

Additional Test Case
• Simple Geometry
• Show how simulation parameters influence result (sensitivity analysis)
• Make results publicly available

Scaling the Number of PersonsDay Case:
• Distribution according to FSS code
there would be more persons in the analysis than the ship is certified to carry
• Problem is solved by scaling the numbers
• This is not in the spirit of the FSS code
Example…
