Using a widely known Weighted Sum Method (WSM) for choosing an information system (IS) from a finite set of candidate multi-attribute information systems to be deployed in an information systems environment, this paper demonstrates that the selected Pareto-optimal IS remains the same provided that the weights remain inside a specified subspace of the weight space. Three cases of IS Environments are discussed and analyzed. The invariance properties hold for other information systems environments if there is a finite number of candidate information systems to be deployed in an IS environment. There is no previous literature describing invariance of the selected Pareto-optimal multi-attribute information system, when weights are inside a designated subspace of the weight space.
