DecideIT

DecideIT is a decision-making software for the Microsoft Windows operating system. It is based on multi-criteria decision making (MCDM) and the multi-attribute value theory (MAVT). It supports both value tree analysis for multi-attribute decision problems as well as decision tree analysis for evaluating decisions under risk and can combine these structures in a common model.

The software implements the Delta MCDM method and is therefore able to handle imprecise statements in terms of intervals, rankings, and comparisons.^[1][2] Earlier versions employed a so-called contraction analysis approach to evaluate decision problems with imprecise information, but as from DecideIT 3, the software supports second-order probabilities which enables a more discriminative power and more informative means for decision evaluation when expected value intervals are overlapping.^[3]

The software has been used for addressing decision problems in various domains, such as evaluation of fuels and biomass systems,^[4][5] district heating,^[6] energy transition,^[7] community decision-making.,^[8] outbreak response measures,^[9][10] selection of tool for digital forensics,^[11] and broadband technology selection.^[12]

DecideIT is developed and maintained by the Swedish company Preference.^[13]
