Adder DT Designer (or shortly Adder Designer) is a tool for the design and analysis of rule-based systems in the form of generalised decision tables, i.e. decision tables with non-atomic values of attributes. The tool is equipped with a decision table editor and verification procedures. At any time, during the designing stage, users can check whether a decision table is complete, consistent and semi-optimal.
For intuition, a decision table is considered to be complete if for any possible input situation at least one rule can produce a~decision. A decision table is deterministic if no two different rules can produce different results for the same input situation. The last property means that any dependent (non-necessary) rules were removed.
Adder Designer is a free software covered by the GNU Library General Public License. It has been implemented in the GNU/Linux environment by the use of the Qt Open Source Edition. Qt is a comprehensive C++ application development framework. It includes a class library and tools for cross-platform development and internationalisation. The Qt Open Source Edition is freely available for the development of Open Source software for Linux, Unix, Mac OS X and Windows under the GPL license. Code written for either environment compiles and runs with the other ones.
