Formulate this scenario as a THERP model. At each branch in the model, estimate the
probabilities of occurrence.
Based on your model in part what is the overall probability of error?
Suggest two design improvements that would reduce error in this scenario.
Develop new estimates of your THERP probabilities based on your design
improvements. What is the new overall probability of error?
What level of error would you define as acceptable for this scenario? Why? Would your
acceptable level of error be different for the scenarios you did not choose?
