In this lecture, we present topics that dont fit nicely in the other lectures, as well
as topics that dont fit in this course due to lack to time. The latters will however be
covered in the

8: Competition
Concordia
November 12, 2015
In this lecture, we consider the effect of competition in supply chains. Competition
arises from the strategic interactions between multiple decision makers with individual
objectives. The to

Network flow problems come in multiple flavors, but they all share a gaphical model.
A graph is a collection of
Vertices V ,
Directed edges E V V .
On each edge (u, v), we assign a weight

October 29, 2015
This week, we first wrap-up the lecture on linear optimization. Then, we discuss
differents ways to communicate about risk, and one way to reduce risk in an inventory
setting.

Take-away messages from the beer game:
Inventory management is hard: optimal inventory is a nontrivial value, neither
too high nor too low.
Making decision takes forever, especia

5: Linear optimization
Concordia
October 14, 2015
All the problems considered so far require only one decision (e.g., one order size)
at a time. Lets look at decision problems involving multiple quantities at the same
time.

4: Stochastic Inventory, Queues
Concordia
October 1, 2015
First, we review how to compute the least-squares forecast in the linear regression
setting. Next, we consider two models of supply chain problems that involve Markov
chains.
