CHAPTER 4
Constraints
Overview
The constraints of a technology are the limitations on the environmental conditions or internal operating conditions under which its transformation process can function efficiently or effectively. The varieties of a technology (in various devices) often differ in how well they can handle changing environmental or internal operating conditions. Thus, for the description of technologies, it is essential to have a terminology that describes these limitations. We use the term constraints in this sense.
The analysis of constraints focuses our attention on the environmental and internal operating conditions of a technology. We describe constraints by showing, in a graph or equation, how the efficiency or effectiveness ...
