Textbook Question
Chapter 4.S, Problem 6P
One of the industrial robots designed by a leading producer of servomechanisms has four major components. Components’ reliabilities are .98, .95, .94 and .90 All of the components must function in order for the robot to operate effectively.
a. Compute the reliability of the robot.
b. Designers want to improve the reliability by adding a backup component. Due to spice limitations, only one backup can be added. The backup for any component will have the same reliability as the unit for which it is the backup. Which component should get the backup in order to achieve the highest reliability?
c. If one backup with a reliability of .92 can be added to any one of the main components, which component should get it to obtain the highest overall reliability?

IM.82 A distributor of industrial equipment purchases specialized compressors for use in air conditioners. The regular price is $50, however, the manufacturer of this compressor offers quantity discounts per the following discount schedule:
Option Plan Quantity Discount
A 1 - 299 0%
B 300 - 1,199 0.50%
C 1,200+ 1.50%
The distributor pays $56 each time it places an order with the manufacturer. Holding costs are negligible (none) but they do earn 10% annual interest on all cash balances (meaning there will be a financial opportunity cost when they put cash into inventory). Annual demand is expected to be 10,750 units.
When there is no quantity discount (Option Plan A, the first row of the schedule listed above), what is the adjusted order quantity? (Display your answer to the nearest whole number.)

Excel Please. The workload of many areas of banking operations varies considerably based on time of day. A variable capacity can be achieved effectively by employing part-time personnel. Because part-timers are not entitled to all the fringe benefits, they are often more economical than full-time employees. Other considerations, however, may limit the extent to which part-time people can be hired in a given department. The problem is to find an optimal workforce schedule that would meet personnel requirements at any given time and also be economical.
Some of the factors affecting personnel assignments are listed here:
The bank is open from 9:00am to 7:00pm.
Full-time employees work for 8 hours (1 hour for lunch included) per day. They do not necessarily have to start their shift when the bank opens.
Part-time employees work for at least 4 hours per day, but less than 8 hours per day and do not get a lunch break.
By corporate policy, total part-time personnel hours is limited…
IM.84 An outdoor equipment manufacturer sells a rugged water bottle to complement its product line. They sell this item to a variety of sporting goods stores and other retailers. The manufacturer offers quantity discounts per the following discount schedule:
Option Plan Quantity Price
A 1 - 2,399 $5.50
B 2,400 - 3,999 $5.20
C 4,000+ $4.50
A large big-box retailer expects to sell 9,700 units this year. This retailer estimates that it incurs an internal administrative cost of $225 each time it places an order with the manufacturer. Holding cost for the retailer is $55 per case per year. (There are 40 units or water bottles per case.)
Based on this information, and not taking into account any quantity discount offers, what is the calculated EOQ (in units)? (Display your answer to the nearest whole number.)
