Many of them describe multi-criteria, hierarchical processes, such as analytic network
process (ANP) and AHP. Some of the papers introduce what might seem like overly
complicated analytical processes, such as fuzzy logic and a concept called technique for
order preference by similarity to ideal solution (TOPSIS). We suppose only the limits of
the imagination can delimit what parametric and non-parametric tools can be applied,
but it seems important that the sophistication and complexity of these match the internal
skills and capabilities of the analysts and managers who shall use them and make
decisions base on them. The AHP process that we are applying in this paper seems to
have just the right level of complexity and sophistication to be understandable and
learnable by most managers with a calculator and a spreadsheet package.
