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.

- 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.
