DELMIA simulation results

Hi! We have two questions regarding simulations in DELMIA Factory Flow Simulation.

1. We would like to know how to easily compare results from different simulations. We know how to extract XML & HTML information but do not know how to show and compare simulation results in a good manner. Any advice on this?

2. How does the calculations of bottlenecks work, and what does the specific chart display? The bars keep shrinking as we simulate, but isn't the bottleneck still the same percentage, or does it depend on how it is calculated?
