Logical Soft Systems Modelling for Information Source Analysis
It has been argued that the Conceptual Models used in Soft Systems Methodology (SSM) are logically inadequate for some of the purposes, notably information system design, for which they are used. In a series of theoretical papers it has been argued that this shortcoming could be rectified by producing logically enhanced versions of the SSM models. The paper describes the use of these models for...
متن کاملAttribute analysis of information systems based on elementary soft implications
Soft set theory provides a parameterized treatment of uncertainty, which is closely related to soft computing models like fuzzy sets and rough sets. Based on soft sets and logical formulas over them, this study aims to present a new approach for revealing the causal relationship between values of attributes in an information system. The main procedure of our new method is as follows: First, we ...
متن کاملA Case For Soft Systems Methodology. Information Analysis And Information Systems Evaluation During Organizational Change
The complex relationship between organizations, information technology (IT) and information systems (IS) indicates that changes to the organization are likely to have an effect on the usefulness of existing IS and the success of IS projects. Information needs of new and existing users have to be assessed and organizational IS evaluated for their capability to satisfy these needs. This paper des...
متن کاملInformation Systems and Soft Sets
It will be shown that each information system can be considered a soft set and each finite soft set can be considered an information system.
متن کاملDynamic consequence for soft information
This article looks at so-called dynamic consequence relations for models of soft information change. We provide a sound, complete calculus for one-step soft dynamic consequence relations. We then study a generalization to sequences of updates, for which we show a number of valid and invalid structural rules.
