QUESTION #4 Four delivery trucks are in a queue at a Tool Company with only one service bay. The trucks are identified by the sequence in which they arrived at the Company. Assume the time is 10:00 a.m. The table shows the times necessary to unload each vehicle and the periods when the commodities they contain are expected in the factory. Determine the schedules that result for each of the rules SPE, CR EDD, and FSFC. In each case compute the average tardiness, the number of tardy jobs, and mean flow time. Truck 1 2 3 4 5 Unloading Time (minutes) 23 16 39 12 30 Time Material is Due 10:15 AM 10:40 AM 10:55 AM 10:30 AM 10:40 AM
Question 7 Station 1 Machine A 20 min/unit Station 1 Machine B 20 min/unit Station 2 12 min/unit Station 3 8 min/unit A three station work cell is illustrated in the image above. A unit needs to be processed at either Machine A or Machine B for Station 1 (parallel lines, both lines doing the exact same thing). The unit is then processed at Stations 2 and 3 before leaving the work cell. What is the process time of this system measured in minutes/unit?
