Abstract:

The decline in the cast of computing has put new decision making tools based on mathematical models and statistical formulae within the grasp of a wide range of commercial organisations. However, mathematical models have their limitations in a business environment and decision making requires more background information than processed numerical data can provide. On-line retrieval systems now provide a facility which can supplement on-line processing of computerised models. Euronet DIANE is one of the most significant European achievements in this field.
