Scientific Engineering Since World War II,
engineering education has moved strongly toward
analysis, with courses dealing with individual
process operations and phenomena. Transport
Phenomena, Unit Operations, Process Control,
Reaction Engineering, and other engineering
science courses greatly strengthened engineering
education by showing how things are and how they
work. Unfortunately, there was not a parallel
development of courses dealing with synthesis
This deficiency has been recognized for years,
but the remedy awaited the development of
sufficiently general principles of synthesis
about which to organize educational
material. (Dale F. Rudd 1973)

The way the plant is designed has a large impact
on how it should be controlled and what level of
control performance can be obtained.

PSE?????

• Process Systems Engineering is concerned with the
  improvement of decision-making processes for the
  creation and operation of the chemical supply
  chain.
• It deals with the discovery, design, manufacture
  and distribution of chemical products in the
  context of many conflicting goals.
• Grossmann and Westerberg (2000)
