tried to express mathematical propositions with logical signs. These efforts led to the emergence of a new branch in logic called mathematical logic. Various logical rules are found in mathematical logic with various symbols, most of which...

This paper addresses a new method for automatically extraction of the fuzzy rules from input-output data. The proposed fuzzy system modeling approach has three significant modules: (1) input selection; (2) knowledge representation; and (3...

Institutions are considered as the constraints on decision makers’ behaviors. Studies analyzing institutions and the management of natural resources have mainly focused on the impact of institutions on the process of ...

Active database systems (ADBS) can, automatically, react to the occurrence of predefined events by definition a collection of active rules. One of the most important modules of ADBS is the rule scheduler, which has considerable impact on performance...
