Reliability Engineering Fundamentals MAE 174 - Fall 2018 Homework # 4 (1)
Consider crossing a street at a cross section with traffic lights for cars and pedestrians. List major tasks, possible failure modes, and relevant performance influencing factors (PIFs) affecting safe crossing. Define and justify the selected PIFs. (2)
Consider the following set of PIF states associated with rectifying an emergency situation at a nuclear power plant: Skill Level Experience Required Resolution Time Potential Emergency Consequence 4 3 6 7 Each PIF is equally weighted with a weighting factor 𝑊
𝑖
. Use the SLIM-MAUD method to calculate human error probability (HEP). The values for parameters ?
and ?
are 1 and -25 respectively. (3)
A SLIM-MAUD model has been developed in isolation for nuclear power plant emergency situation by another team of human reliability engineers. Their model outputs for different scenarios (same SLIM-MAUD model) are as follows: Skill Level Experience Required Resolution Time Potential Emergency Consequence HEP 5 2 8 9 0.36879 4 4 5 6 0.00025 Is the SLIM-MAUD model developed in isolation the same as the SLIM-MAUD model used in question (2)?
