Reconstruction of Cooperative Information Systems under Cost Constraints: A Rough Set Approach

In the paper 16] has been proposed a method for synthesis of cooperative information systems 4] speciied by data tables 10]. On the base of this method it has been elaborated and presented in the paper 17] a strategy for reconstruction of the synthetized cooperative information system when the speciication for the system is being changed. The aim of this paper is to present an approach for the reconstruction of the synthetized system under cost constraints. This approach is based on rough set theory and it can be applied in the system technology domain to adaptive reorganization of existing cooperative information systems (cf. 13], 5]).
