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).
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.
