Exam 19: Work Measurement, Learning Curves, and Standards

A manufacturer made a commitment to supply 20 units of a product.The first unit took 1,200 hours to make, the second unit took 900 hours and the third unit took 768 hours.How many hours should it take to make the 20^th unit?

For a work sampling study, there is a 95% probability that the processing time of an activity has an error of less than 0.06 minutes.The best estimate we have for "p" is 0.30.Determine the sample size needed for a work sampling study if no estimate of p is available.

For a work sampling study, there is a 95% probability that the processing time of an activity has an error of less than 0.06 minutes.The best estimate we have for "p" is 0.30.Determine the size sample that should be used for this work sampling study.

Normal time needs to be adjusted for personal time and avoidable delays.

All of the following are advantages of using regression analysis to determine standard time except

After developing a pre-determined standards, stop-watch or work-sampling times studies need not be performed.

Define work measurement and what it leads to from an operations perspective.

Locksmith Inc.has an order from a bank for 50 specially designed safes, one for each bank branch.It is estimated that the first safe will require 75 hours of shop time and a 90% learning curve is expected.The labor rate is $15.00 per hour and the pricing policy of the company is to triple the labor cost of the order. a.How many labor hours should the 50th unit require? b.How many labor hours will the whole order require? c.What is the customer's price for each safe?

Personal fatigue and delay allowances are added to ____ to arrive at ____.

The ____ states that the cost of doing any repetitive task, work activity or project decreases as the accumulated experience of doing the job increases.

Work standards

Allowances include time for all of the following except

Differentiate between an experience curve and the traditional learning curve.

Job and process analysis should follow work measurement.

The groups best suited to set work standards are managers with input from industrial engineers.

A fast food stand has a thriving business in downtown Portland.They serve 3,500 burgers, 3,000 orders of fries, and 4,000 soft drinks per week.The workers all work 40 hours per week but are idle two percent of the time.The manager wants to try to become more efficient.He has done a time study and found: It takes 1 additional minute per additional item.The average order size is 3 items. a.What is the average number of orders per week? b.What is the average cycle time (in minutes) per order? c.What is the labor standard (in minutes) per order? d.How many workers does the manager need per week?

A company manufactures tractors and lawnmowers.They have received an order for six deluxe custom riding lawnmowers for a local golf course.They must develop a cost estimate for the order.It is estimated that the first lawnmower will take 90 hours of shop time and a 75% learning curve is expected.The labor rate is $18.00 per hour and the pricing policy of the company is to charge 2.5 times the cost of labor for the order. a.How many hours should the sixth lawnmower take? b.How many labor hours should the whole order take? c.What is the customer's price for the whole order? d.What is the price per lawnmower? e.If the original time estimate for the first lawnmower is too low and it actually takes 80 hours for the third lawnmower, what is the labor hour estimate for the first unit? f.If it actually really takes 80 hours for the third lawnmower, what is the new total labor cost for the entire order?
