ABSTRACT
Computer software is a tool-of-the-trade for engineers. The capabilities provided by computers for fast calculation, large storage, and logical decisions, plus the available technical and mathematical software, permit engineers to solve large problems and to do it much more rapidly than ever before. The engineers’ emphasis can therefore shift from problem solving to planning, conceiving, and interpreting with the information made available. Process design is one of the engineering functions that has been impacted by computers (Peters and Timmerhaus, 1991).
