An injector machine goes down roughly 20% of the time (the injector gums up and needs to be cleaned, a quick process). One operator is assigned to service three identical such machines. Each machine can produce 100 parts/h if running properly (i.e., not down). The operator is paid $10/h and each machine costs $20/h to operate. Consider 8hr/shift a) Please fill in the table below: b) How many parts can you produce per shift? c) What is the unit cost fper part for this operation? d) If you hire another operator at the same rate to assist the first operator, what is the unit cost now? e) Is it worth hiring another operator at the same rate to assist the first operator, in case more than one machine goes down at the same time?

- A Printed Circuit Board (PCB) machine installs integrated circuits onto a board. Before starting to produce a board, the PCB machine requires a 16-minute setup. Once in production, the PCB machine requires only 0.19 minute per board. a. Currently, the PCB machine produces 525 boards between setups. Given this operating process, what is the capacity of the PCB machine (in boards per min)? b. Currently, the PCB machine produces 525 boards between setups. Given this operating process, what is the utilization of the PCB machine? c. Say the PCB machine produces 400 boards s between setups and demand is 2 boards per minute. Given the operating process, what is the avergae inventory of boards anf the PCB machine? d. Demand for boards occurs at the rate of 2 boards per minute. What is the smallest batch size such that the PCB machine does not constrain the flow rate through the process?A graphics reproduction i rm has four units of equipment that are automatic but occasionallybecome inoperative because of the need for supplies, maintenance, or repair. Eachunit requires service roughly twice each hour, or, more precisely, each unit of equipmentruns an average of 30 minutes before needing service. Service times vary widely, rangingfrom a simple service (such as pressing a restart switch or repositioning paper) to moreinvolved equipment disassembly. The average service time, however, is i ve minutes.Equipment downtime results in a loss of $20 per hour. The one equipment attendant ispaid $6 per hour.Using i nite queuing analysis, answer the following questions:a. What is the average number of units in line?b. What is the average number of units still in operation?c. What is the average number of units being serviced?d. The i rm is considering adding another attendant at the same $6 rate. Should the i rmdo it?A heat tempering machine tempers a surgical instrument in exactly 2 minutes. Surgical instruments arrive at the rate of 20 units per hour.

- 10. Two operators handle adjustments for a group of 10 machines. Adjustment time is exponentiallydistributed and has a mean of 14 minutes per machine. The machines operate for an average of86 minutes between adjustments. While running, each machine can turn out 50 pieces per hour.Find the following:a. The probability that a machine will have to wait for an adjustmentb. The average number of machines waiting for adjustmentc. The average number of machines being servicedd. The expected hourly output of each machine, taking adjustments into accounte. Machine downtime represents a cost of $70 per hour; operator cost (including salary andfringe benefits) is $15 per hour. What is the optimum number of operators?An operation uses 120 Kilos of a certain material each day. Material is transported in containers that hold 20 kilos each. The plant operates on an 8 hours/day. assume that the inefficient factor for 8 this operation is 0.25. If the manager wants to have the number of containers exactly 3 per day, what would be the cycle time for container of this machine operation in hours?The question comes out of my "Practical Operations Management's" textbook. Tube Country rents circular rubber rafts that its customers use to float down the Ichituckni River. Tube Country owns a fleet of 200 rafts, each of which is returned on the same day it is rented, and each raft can only be rented once during a business day. Rough water along the Ichituckni River often causes rafts to become scratched and leak air, so the staff at Tube Country is constantly repairing rafts before their next rental. As a result, Tube Country estimates that 5% of its rental fleet is unavailable for rent at any given time. Tube Country rents rafts for $5 each, and incurs $1.00 in variable costs with each raft rental. Tube Country must also pay $20,000 in fixed business costs annually. How many rentals does Tube Country need to break even each year? How many rentals does Tube Country need to make in a year to earn $5,000 in profit? Last year, the owner of Tube Country, Mr. Robert “Bobber” Gowdy, had…

If the clerk is occupied on one line, incoming phone calls to the catalog department are answered automatically by a recording machine and asked to wait. As soon as the clerk is free, the party who has waited the longest is transferred and serviced first. Calls come in at a rate of about 10 per hour. The clerk can take an order in an average of 4.0 minutes. Calls tend to follow a Poisson distribution, and service times tend to be negative exponential. The cost of the clerk is $8 per hour, but because of lost goodwill and sales, Janson's loses about $25 per hour of customer time spent waiting for the clerk to take an order. a) The average time that catalog customers must wait before their calls are transferred to the order clerk = minutes (round your response to two decimal places). b) The average number of callers waiting to place an…Janson's Department Store in Stark, Ohio, maintains a successful catalog sales department in which a clerk takes orders by telephone.

- A Printed Circuit Board (PCB) machine installs integrated circuits onto a board. Before starting to produce a board, the PCB machine requires a 20-minute setup. Once in production, the PCB machine requires only 0.15 minute per board. Assume there is ample demand. Demand for boards occurs at the rate of 2 boards per minute. What is the smallest batch size such that the PCB machine does not constrain the flow rate through the process? answer:_________batch sizeA company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used five workers, who produced an average of 80 carts per hour. Workers receive $10 per hour, and machine cost was $40 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $10 per hour, while output increased by four carts per hour.A) Compute labor productivity under each system. Use carts per worker per hour as themeasure of labor productivity.B) Compute the multifactor productivity under each system. Use carts per dollar cost (laborplus equipment) as the measure.C) Comment on the changes in productivity according to the two measures, and on which one you believe is the more pertinent for this situation.Performance Evaluation and Risk Aversion Jill Lewis is the office manager of PureBreds Inc.Her office has 30 employees whose collective job is to process applications by dog owners whowant to register their pets with the firm.
