Answer C only. Tim Woods, a recent GMU MBA grad and serial entrepreneur, has opened Pets-R-awesOMe, an online pet store. He and his team are experimenting with call center staffing. A. The current call center format has two lines: one for customers who want to place an order and one for customers who want to report a problem. Each line is served by one specialized customer service representative. The call center is staffed so that at any given time, there is one representative taking customer orders and one representative addressing customer problems. On average, there is a new customer who wants to place an order every two minutes, exponentially distributed. Similarly, there is a new customer needing to address a problem every two minutes, exponentially distributed. The call center staffers are fast and can on average complete one call of either type in 75 seconds, with a standard deviation of 30 seconds. Each call center staff member is paid $15 per hour. The estimated cost of a…

Five customers brought in computers to be repaired to a small shop. Estimated repair times (in days) and dates promised are given below. Due dates were set based on available technicians; however, one technician had a medical emergency and will be unavailable for at least two weeks so processing times were adjusted. Customer job 1 Processing time (days) Due date (days) 6 Use the EDD rule and compute the start time, flow time, lateness, and tardiness for each job. Use minus sign to enter negative lateness values, if any. If your answer is zero, enter "0".

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?

Three jobs are in the queue. The number of tickets each has and the number of seconds of processing time each requires are shown in Table 2. Assume that quanta of CPU time are sufficiently small, and that no other processes get any tickets before the last of these processes complete. For the following questions, please circle the correct answer from the candidate list. Table 2 Using lottery scheduling algorithm, Job # Tickets CPU time turnaround time for Job 1 is 30 10 (a) 20 (b) 25 (c) 30 (d) 35 2 30 15 turnaround time for Job 2 is (a) 20 (b) 25 (c) 30 (d) 35 3 40 10 turnaround time for Job 3 is (a) 20 (b) 25 (c) 30 (d) 35 average turnaround time is (a) 20 (b) 25 (c) 30 (d) 35 When using lottery scheduling algorithm, what is the turnaround time for Job 1, Job 2, and Job 3? And what is the average turnaround time? 1.

state whether or not each situation would be considered “compensable time” (and why or why not). An employee of a fast food chain has to arrive at work 15 minutes early to change into the“mascot” costume and it typically takes another 15 minutes at the end of the shift to change outof the costume and properly store it. Due to the cost of the costume, employees are notallowed to take the costume home. The “mascots” typically work from 10am – 2pm, to coverthe lunch rush periods. How much time would be “compensable” for the mascots, assumingthe conditions/schedule listed above?2) George is a Radiology Technician at a local hospital and when on call, is required to be nofurther than 30 minutes away from the facility. Is the “on call” time, compensable?

So how to calculate the following below: Avg. lateness = ? days Avg. completion time = ?? days Avg. number of jobs in the system = ? jobs
