Tracing in FoodChain-Lab

Tasks

• Use the example workflow from https://github.com/SiLeBAT/BfROpenLa….
• Visualize the forward and backward trace of a station via the Tracing View.
• Deactivate “Cross Contamination” for the black station and see how the trace changes.

Step 1

• Import the Example Workflow from https://github.com/SiLeBAT/BfROpenLa….
• Open the Tracing View by double-clicking on it.

Step 2

• In the delivery graph you can see 9 Outbreak stations (red) and one station where Cross Contamination is assumed (black).
• The size of each station is based on its “Score”, which depends on the Outbreak stations that can be reached from the station.

Step 3

• We will now observe the trace of a single station in detail.
• Set “Picking” as Editing Mode and double click on the station in the red circle.

Step 4

• A dialog will pop up, that all attributes of the station.
• Additionally you can change “Weight”, “Cross Contamination”, “Kill Contamination” and “Observed”.

Step 5

• Select Observed and press OK.

Step 6

• All stations/deliveries of the forward trace are orange-colored and the ones of the backward trace are purple.
• Three Outbreak stations are also orange striped now. That means they are also on the forward trace of the observed station.

Step 7

• Let’s see what happens if we deactivate cross contamination in the station in the red circle.
• So double click on it.

Step 8

• Uncheck CrossContamination and press OK.

Step 9

• Deactivating cross contamination changed the forward trace of the observed station.
• Now two of Outbreak stations, that were striped before, cannot be reached anymore.
