‘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)

什麼是 『程序系統工程』﹖
5
根據 Takamatsu (1983)在第一屆國際PSE研討會
(Kyoto,1982)所提出的定義，PSE是 "...academic and technological field related to methodologies for chemical engineering decisions concerning how to plan, design, operate and control chemical processes." Takamatsu更進一步建議將PSE列為化工的基本訓練之一，這是因為其他課程著重單元操作中的物理化學現象之瞭解，而PSE 則採取整體流程觀點，分析並設計由許多單元組成的系統。
6
PSE的內容 程序設計 (Process Design) 程序控制 (Process Control)
程序操作 (Process Operation)

“You cannot make a garbage truck drive like a Ferrari!”
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. “You cannot make a garbage truck drive like a Ferrari!”

未來展望
34
Grossmann and Westerberg (2000)
PSE領域之擴展 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)
36
Process and Product Design
Molecular design Process intensification Design of sustainable and environmentally benign processes Synthesis of microchips and bioprocess systems Design and analysis of metabolic networks
37
Process Control Integration between design and control
Applications in bioprocesses and biomedical devices Plant-wide control Hybrid systems Sensors
38
Process Operation Optimal planning and scheduling for new products
