Quality of data model for supporting mobile decision making

摘要

This paper describes research towards implementation of a mobile decision support system. Our view is that the mobile decision maker will benefit if provided with a measure of the Quality of the Data (QoD) used in deriving a decision, and how QoD improves or deteriorates while he/she is on the move. We propose a QoD model taking into account static and dynamic properties of the mobile decision context, and use multicriteria decision analysis to represent decision model and derive a QoD measure. A prototype mobile decision support system has been developed to investigate the usefulness of the proposed QoD model.
