Question Complete the following table. Customer Arrival Time Service Time Finish Time Wait Time 1 0 10 2 3 3 3 8 7 4 10 21 5 15 11 6 28 8 Assume there are two queues, what is the average waiting time?
- (10 Points) Eat well is a small drive through fast food restaurant, staffed by anefficient employee John, is located in a super mall area. Customers arrive at thecounter at an average of one every 15 minutes, and the customer arrival followsa Poisson distribution. John takes at most 10 minutes to process each foodorder.a) What is average number of customer being served at any time?b) The expected number of customers waiting to be served.c) Compute the average time customer wait in the system.d) Compute the average time customer wait in the line.e) What percentage of time is John Idle?Short question 4- Leo manages a receiving station for rice. Farmers deliver their loads of rice with a rate of 150 tons per hour from 6:00 am to 2:00 pm. Leo can process them at a rate of 100 tons an hour. The station has room to hold only 200 tons of rice in inventory prior to processing. Once this space is filled, the farmers’ trucks must wait to dump their contents. Leo is considering using seasonal workers to help him with the processing of rice loads. When the seasonal workers are working, the processing rate increases to 125 tons per hour. The seasonal workers would start working at 10:00 am and finish working when the trucks stop waiting. At what time, Leo will finish processing loads of rice using these seasonal workers?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
