GRAI method
Introduction The '''GRAI method''', GRAI is short for  Graphs with Results and Actions Inter-related, and the further developed GRAI IntegratedMethodology (GIM) is a modeling method of Enterprise modelling. The GRAI method was first proposed by Guy Doumeingts  in his 1984 PhD thesis, entitled ''La Méthode GRAI'', further developed at the GRAI/LAP (Laboratory of Automation and Productics) of University Bordeaux I, and followed by GRAI/GIM by Doumeingts and others in 1992.The GRAI method can represent and analyze the operation of all or part of a production activity. The strength of the GRAI method lies in its ability to provide modelers can effectively model the decision-making system of the company, i.e. organizational processes that generate decisions.In the GRAI methodology four types of views had been incorporated: the functional view, physical view, decisional view and informational systems view.
