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
N
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
R
based on the subjective factors.
