DEX Software is powered by method DEX and aimed at:
DEX (Decision EXpert) is a is a hierarchical, qualitative, rule-based multi-criteria decision analysis (MCDA) method. It is particularly suited for sorting/classification decision problems. DEX puts special emphasis on the transparency, comprehensibility, consistency, and completeness of decision models, as well as on methods for the analysis, justification, and explanation of decisions.
The DEX approach relies on using software tools that actively support the decision maker in both the creation and utilization stages of the process. We are the principal developers of DEX, dedicated to creating high-quality, state-of-the-art and free-to-use DEX software.
DEXi Suite is a common name for the new-generation of DEX software, aimed at gradually replacing DEXi Classic. DEXi software has been redesigned and rebuilt from the scratch in order to:

models
DEXi Classic is a reliable and trusted de-facto implementation of the DEX method since 2000.
The main software component is DEXi, a desktop program for multi-attribute decision making, which facilitates an interactive creation and editing of DEX models (attributes, their hierarchy and scales, decision tables, and alternatives) and provides methods for the evaluation and analysis of alternatives (what-if analysis, “plus-minus-1” analysis, selective explanation, comparison of alternatives, option generation). DEXi Classic also provides software for the evaluation of alternatives on Web pages and programming environments, such as C# and Java.
The following DEX software is not functional nor supported any more:
DEX applications are generally of two types: one-time and recurring.
Making one-time decisions is a classic MCDM task in which, given a set of decision alternatives, the goal is to choose the best alternative or to rank/sort them according to decision maker’s preferences. Results of one-time applications are rarely published online, but you may find them in various reports and articles (see Documentation for examples).
Recurring decisions are essentially one-time decisions that occur periodically in similar circumstances. Often, they lead to development of some software, such as Decision Support Systems (DSS), that take care of evaluating and analysing new and new decision alternatives in recurring situations. Here are some examples of Web pages and DSSs that employ DEX models:
