Abstract

A first order inference system, named R-calculus, is defined to develop the specifications. This system intends to eliminate the laws which are not consistent with users’ requirements. The R-calculus consists of the structural rules, an axiom, a cut rule, and the rules for logical connectives. Some examples are given to demonstrate the usage of the R-calculus. Furthermore, the properties regarding reachability and completeness of the R-calculus are formally defined and proved.
