Aggregating data for decision support

摘要

Numerous strategic and tactical decisions in organisations are based on aggregated data. A simulation-based inquiry of a Multiple Store Company leads to the conclusion that aggregation of data on local decisions does not give insight for taking global decisions. This implies that one has to question the validity of management information produced through aggregation in numerous data processing systems. It also signifies that application of models based on definition and behavioural equations can be dangerous. Simulation-based inquiry systems are, however, capable of providing support even in these circumstances With a simulation-based decision support system for global decision-making we may analyze through disaggregation the effects of these decisions at local levels. By using a problem-solving environment based on system description and simulation, effective decision support systems can be developed efficiently.
