(All Chapters)
CHAPTER 1 - Introduction to Facility Design
1.4 Solutions
1. This is an open-ended question and could be given as a mini-project for students.
2. Design problems are those that have a longer time span, typically three to five
years or more, whereas planning problems have a shorter time span. Students
will come up with a long list of design and planning problems and Figure 1.1
should be of some help. Although it is desirable to solve the two problems
simultaneously, so that a solution satisfies design and operational performance
measures, doing so makes the problem intractable and hard to solve.

, CHAPTER 2 – Supply Chain Design
2.6 Solutions
1. Students are encouraged to consult business publications and trade magazines
to identify the supply chain design and operational trends witnessed in the past
15 years.
2. Once again, a consultation of business publications and trade magazines will help
the students identify companies in the disruptive innovation space.

, CHAPTER 3 – Logistics and Location Models
3.11 Solutions
1. As indicated in Section 3.1 as well as Chapter 1, facility location must be
addressed in the very early stages of facility design – as soon as the products to be
produced and markets to be served have been identified.
2. Facility location is a sub-problem in logistics management. As defined in Section
3.1, logistics management covers not only location, allocation, but also the
distribution methods, costs, and a number of other logistics related factors.
3. It should serve the needs of the company, minimize costs, must mesh well with
the existing network of supply chain of suppliers, plants and customers, etc. This
is a good question for in-class discussion.
4. See Section 3.3.
5. See Section 3.3.
6. See Table 3.1.
7. This is an interesting project for undergraduate students that could be
supplemented with in- class discussion.
8. Based on the calculations done in the table below, we find that site #6 is the
best location based on the subjective factors.
