The role of the subject in the modelling of a complex system is discussed. It shows that the main problem in the modelling of complex systems derives from the complexity of the systems themselves and not from the short comings of the particular methodology. The article continues with the general simulation model of the business system described by Forrester's system dynamics. The methodology is sufficiently abstact to allow a qualitative and quantitative analysis of system functioning through feedback loops. The multiple criteria function used for the evaluation of different scenarios was defined with the aid of a decision group using the group support system. The methodology was successfully tested on real cases.
