Tabular Decision Logic for Structural Design

As computer applications shift from analysis to design, increased attention must be given to algorithms which are primarily logical in character. The common approach to the programming through involved flow-charts has been generally found unsatisfactory. The technique of tabular decision logic provides one means of formulating complex logical decisions. The technique is described and illustrated. It is shown that the technique eliminated most of the shortcomings of conventional flow-charting. The application of the technique is contingent on the availability of clear, precise rules defining engineering decisions. The paper concludes with a brief description of the conversion of decision tables into conventional flow diagrams and of some processors which convert decision tables directly into execution programs.
