The true pairwise comparison matrix is simulated and used as a benchmark for evaluating different priority vectors derived from a decision maker's pairwise comparison matrix. The accuracy of the decision maker's comparisons are progressively improved until they emulate the true values. Using four different distance measures to evaluate five...

In his article, “How Solid is the Dutch (and the British) National Risk Assessment,”(1) Dr. Charles Vlek evaluates the Dutch National Risk Assessment methodology (DNRA) based mainly on the 2009 method guide.4(2) Since we value methodological diversity, useful evaluations, and suggestions that help us cope with methodological and other problems,...

Judgement-based (or ‘soft’) Operational Research (OR) is used in Defence, although it may not be well known and understood and it may not be perceived to have the rigour of more quantitative techniques. A NATO task group was set up to address these features and to produce a Code of Best Practice with the purpose of: creating an understanding of...

Judgment plays an important role in all Operational Analysis (OA). NATO practitioners have determined that approaches in OA that are based on human judgement are increasingly critical to defence decision making. The purpose of the NATO Guide for Judgement-Based OA in Defence Decision Making is to create an understanding of what judgement-based...

Nowadays, National Safety and Security issues receive much attention in many countries. In 2007, the Dutch government approved a National Safety and Security Strategy based on a multi-criteria analysis approach to classify potential threats and hazards. The general methodology of this Dutch National Risk Assessment and the specific multi...

This note comments on a paper by Triantaphyllou (J. Multi-Crit. Decis. Anal. 2001; 10: 11–25) that attempts to demonstrate new types of rank reversal that can occur with the analytic hierarchy process (AHP). He contends that the reversals are attributable to the various types of normalization that are used with the addition step in AHP synthesis...

A non-discriminating criterion is defined as a criterion where the decision-maker is indifferent among the alternatives. One would therefore expect the final rank order of the alternatives not to be affected by removing it. A previously published paper by Finan and Hurley (Comput. Oper. Res. 2002; 29: 1025–1030) showed that in the analytic...

This paper shows that the usual multiplicative synthesis of alternative priorities for benefits, opportunities, costs and risks, obtained from separate Analytic Hierarchy or Network models, can be ambiguous. The ratio of benefit and opportunity priorities to cost and risk priorities can be misleading when assessing the profitability of a project...

This note builds on a previous theoretical investigation of the validity of the synthesis of composite priorities on benefits, opportunities, costs and risks that were obtained from separate Analytic Hierarchy or Network models. More specifically, this note uses different monetary scenarios with known results that are all based on a common set...

Rank reversal can occur in the Analytic Hierarchy Process when alternatives are added or deleted. Recently, it was found that removing a non-discriminating criterion could cause the same phenomenon. This paper offers an explanation of these rank reversals and shows how they can be avoided through a link between the normalization and weighting...

Traditional Benefit/Cost analysis requires benefits and costs to be expressed in a common currency, usually dollars. More recently, benefits and costs have been expressed and compared as relative priorities. This process has been criticized because there is no guarantee that the two sources of priorities are in commensurate units. This paper...
