Advanced Assembly, Inc. manufactures machine parts. One assembly line has a robotic welding station that takes a fixed time of 37 seconds to perform its welding operation. Parts come down the assembly line at a rate of 65 per hour, following a Poisson distribution. a. Determine the average number of parts waiting to be welded at this station. b. Calculate the average time a part waits at this station before welding begins. c. What percent of time is the robot idle (not welding)? d. What is the average time a part spends at this station (including time in line)? Advanced Assembly, Inc. manufactures machine parts.
