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?

Chairs are made in a process with a single resource. There are two types of chairs. The resource's processing time for the first type is 30 minutes and demand for this type is 2.3 chairs per hour. The resource's processing time for the second type is 23 minutes and demand for this type is 2.8 chairs per hour. There is 1 worker at this resource. Instruction: Round your answer to one decimal place. What is the implied utilization (%) of this resource?
Wally's Widget Warehouse takes orders from 7 A.M. to 7 P.M. The manager wants to analyze the process and has provided the following process flow diagram. There are three steps required to ship a customer order. The first step is to take the order from a customer. The second step is to pick the order for the customer, and then they have to pack the order to ready it for shipping. The order-taking step works at a maximum rate of 100 customer orders per hour. Order picking works at a maximum of 75 per hour, and packing works at 60 per hour. Customers Order Taker 100 Customers/ hour Current maximum output Pick orders Pack orders Customer Orders Pick Orders 75 Customers/ hour hours hours Picked Orders Wally wants to figure out the following. a. What is the current maximum daily output of the process assuming that no one works overtime? (i.e., meaning all three operations work a 12-hour shift) units per day Pack Orders 60 Customers/ hour Wait for Shipper b. How long (in hours) will the…

The 4M company has a lathe as the centerpiece of the plant's work. The jobs arrive according to a Poisson process with an average rate of 2 per day. The processing time of each job is exponentially distributed with an average of 1/ 4 day. Since the jobs are large, if they are not in process they are stored in a warehouse some distance from the machine. However, to save time in bringing them in, the production manager proposes to add space for 3 in-process jobs in addition to the one on the lathe (the rest will continue to be stored). With this proposal, what proportion of the time will the space next to the lathe be adequate for the waiting jobs? Calculate your answer using the formulas available.
Suppose for a particular process that the bottleneck cycle time is 54 seconds, and raw processing time is 345 seconds. If there are 4 customers in this system already, and then you walk up and join the line at Station 1, what is your expected lead-time to move through the entire process? Whole number value, no decimals.
