For [[group decision-making]], the '''hierarchical decision process''' ('''HDP''') refines the classical AHP [[Analyticanalytic Hierarchyhierarchy Processprocess]] (AHP) a step further in eliciting and evaluating subjective judgements. These improvements, proposed initially by Dr. Jang Ra (a student of Dr. Saaty [[Thomas L. Saaty]] who developed and refined AHP) include the constant-sum measurement scale (1-991–99 scale) for comparing two elements, the logarithmic [[least squares method]] (LLSM) for computing normalized values, the sum of inverse column sums (SICS) for measuring the degree of (in)consistency, and sensitivity analysis of pairwise comparisons [[Matrix (mathematics)|matrices]].

HDP refines the classical AHP [[Analytic Hierarchy Process]] a step further in eliciting and evaluating subjective judgements. These improvements, proposed initially by Dr. Jang Ra (a student of Dr. Saaty [[Thomas L.

These subtle modifications address issues concerning normal AHP consistency and applicability in the process of constructing hierarchies: generating criteria, classifying/selecting criteria, and screening/selecting decision alternatives. IEEE has a link to the five page pdf in Technology Management: the New International Language, 27-31 Oct 1991, pp.&nbsp;595–599, ISBN 0-7803-0161-7 [http://ieeexplore.ieee.org/xpl/RecentCon.jsp?punumber=586], although it costs about $29.95.
