A Graph Based Modeling Tool

Aim To study the modeling tool,the key part of the model base unit in a decision support system.Methods Based on the train of analysis followed by C.V.Jones and through a study of graph based modeling system (GBMS),the theoretical features of the graphical modeling system and available techniques are printed out,and the characteristics of modern modeling and the theory of GBMS discussed in some depth.Results A prototype GBMS/process is realized.Conclusion An objective evaluation of the system is shown together with proposals for its future development.
