Swift, Andrew W.
National Grid USA
This project sought to determine whether spot or group relamping would be a more efficient maintenance system for National Grid. Through interpolation and extrapolation of partial survival functions, we constructed a probability distribution for the failure time of one lamp. We used rejection sampling to draw failure times from our density function, and computed the number of failures of a group of lamps over a period of time. We were then able to estimate when spot or group replacement prevailed.
