"The determination of overdesign, or safety, factors for industrial processes is an art acquired by the engineer through experience. In general, safety factors are increased as the uncertainty of the process variable increases; a procedure that can be expensive if safety factors are specified too small or too large. A single release of harmful substances from pollution control installations may cause irreparable damage. Likewise, the production of an off specification product by a chemical process costs money and resources. These facilities must often be designed for widely fluctuating flow rates, compositions, temperatures, and etc. Consequently, the selection of the proper safety factors is a difficult and critical aspect of any design study.

A method for the quantitative determination of process overdesign has been developed based upon stochastic simulation of a computer model of the process. This study outlines and presents the results for a typical chemical process design and for a conventional water treatment facility"--Abstract, page ii.
