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.

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