Abstract:

The main contribution of the paper is to provide an approach to evaluating proposals for handling inconsistency in requirements.In a given scenario，for each proposal of inconsistency handling，the expected responses of the system－to－be that can be derived from a modied requirements specication are concerned with，which results from performing the proposal.The relative importance of these expected responses in the scenario may be viewed as an abstraction of suitability of the proposal.From this sense，utility vector function to measure the degree of suitability of each proposal is presented.Then compare two proposals using their utility vector function values.It gives an intuitive ordering relationship over these proposals that can be described as“more appropriate than”.These techniques provide a basis for choice of inconsistency handling proposals in requirements engineering.

Key words: requirements engineering, inconsistency handling, utility vector function
