Uncertainties in the Analytic Hierarchy Process

When choosing a decision analysis technique to model a particular complex decision the fundamentals of the technique chosen should be understood by the analyst, and they should be appropriate for the characteristics of the problem itself. For analysing such complex decisions the Analytic Hierarchy Process is one of the most commonly used techniques. This technical note highlights a number of theoretical issues, some well-known and others less well-known, that introduce a considerable degree of uncertainty into the computed output priorities for the decision alternatives.
