Consider the decision-making problem of opening a new restaurant when facing Covid-19 risk. I further revised my Bayesian causal network (influence diagram) for this problem as below.

In my revision, I add two more nodes, Government Covid-19 Regulation (Gov. Reg.) and Restaurant Floor Plan.

I assume Government Covid-19 Regulation is a child (i.e., direct effect) of Exposure to Covid-19 and a parent (i.e., direct cause) of Revenue.

Furthermore, I assume Restaurant Floor Plan is a parent of Revenue and a child of Location. In addition, Season is also a parent of People Flow.

Finally, I treat Location and Floor Plan are two decision nodes. Briefly explain why my assumptions of

1. Government Covid-19 Regulation is a child (i.e., direct effect) of Exposure to Covid-19 and a parent (i.e., direct cause) of Revenue.

2. Restaurant Floor Plan is a parent of Revenue and a child of Location.

3. Season is also a parent of People Flow.

are reasonable causal assumptions.
