Abstract—an ontology-based framework of Requirements Evolvement Management (REM) is proposed for controlling requirements evolvement and tracing requirements which are the important aspects of REM. The ontology is introduced to describe the information about requirements evolvement. Consistent analysis and influence analysis for requirements evolvement is researched in the process of REM. The inconsistency of requirements is verified through the manipulations of ontology, and different inconsistency is dealt in different ways. A layered dependence tree of requirements is built according to the dependent relationship between requirements to support the layered managements of requirements and an equation of cost analysis is defined to count the priority of requirements which are in the same layer.

Index Terms—ontology, requirements evolvement, consistent analysis, influence analysis
