Caselet 1
Orion is a global co. That sells copiers. Orion currently sells 10 variants of a copier, with all inventory
kept in finished-goods form. The primary component that differentiates the copiers is the printing
subassembly. An idea being discussed is to introduce commonality in the printing subassembly so
that final assembly can be postponed and inventories kept in component form. Currently, each copier
costs $1,000 in terms of components. Introducing commonality in the print subassembly will increase
component cost to$1.025.One of the 10 variants represents 80 percent of the total demand. Weekly
demand for this variant is normally distributed ,with a mean of 1,000 and a standard deviation of
200.Each of the remaining nine variants has a weekly demand of 28 with a standard deviation of
20.Orion aims to provide a 95per level of services .Replacement lead time for components is four
weeks. Copier assembly can be implemented in a matter of hours. Orion manages all inventories
using a continuous review policy and uses a holding cost of 20 percent.
Questions:
1. How much safety inventory of each variant must Orion keep without component commonality?
What are the annual holding costs?
2. How much safety inventory must be kept in component form if Orion uses common components
for all variants? What is the annual holding cost? What is the increase in component cost using
commonality? Is commonality justified across all variants?
3. At what cost of commonality will complete commonality be justified.
4. At what cost of commonality will commonality across the low-volume variants be justified.
Caselet 2
An electronic manufacturer has outsourced production of its latest MP3 player to a contract
manufacturer in Asia. Demand for the players has exceeded all expectations whereas the contract
manufacturers sell three types of players- a 40-GB player, a 20-GB player, 6-GB player. For the
upcoming holiday season, the demand forecast for the 40-GB player is normally distributed, with a
mean of 20,000and a standard deviation Dard deviation of 11,000, and the demand forecast for the 6-
GB player has a mean of 80,000 and a standard deviation of 16,000. The 40-GB player has a sale

price of $200, a production cost of $100, and a salvage value of $80 .The 20-GB player has a price of
$150, a production cost of $70, and a salvage value of $50.
Questions:
1. How many units of each type of player should the electronics manufacturer order if there are no
capacity constraints?
2. How many times of each type of player should the electronics manufacturer order if the available
is 140,000? What is the expected profit?
1. Consider two products with the same margin carried by a retail store. Any leftover units of one
product are worthless. Leftover units of the other product can be sold to outlet stores. Which
product should have a higher level of availability? Why?
2. McMaster-Carr sells maintenance, repair, and operations equipment from five warehouses in the
United States. W.W. Grainger sells products from more than 350 retail locations, supported by
several warehouses. In both cases, customers place orders using the Web or on the phone. Discuss
the pros and cons of the two strategies.
