Classical models of economic processes are hampered by the fact that crisp mathematical formulae seldom exist, as human behaviour does not follow differential equations. In addition, optimisation of strategic decision-making is difficult for managers when business information systems confront them with megabytes of data to study. In this paper, the concepts of the Balanced Scorecard and of decision support systems based on Fuzzy Logic are combined into a methodology and a software tool that is able to help executives to optimise their strategic business processes. The tool, ActiveScoreCard is used successfully by the Austrian Research Centers.
