Research into the primitive classification system of the visual management of coal enterprise

Based on entity classification system of visual management research has been the focus of research on the application of visual management in coal enterprises.However,the achievements on it is a few for that the classification methods,standards of classification the theoretical system have not been formed yet.Through investigating and analyzing the status,and summarizing the objects of today's coal enterprises which include those in national and industrial standard,this thesis try to build the system in two level:basic entity classification system and professional entity classification system.The four-level basic entity classification system is formed by the way that:taking the professional classification of coal enterprises as the independent variable and the basic classification of "point,line and surface" as the dependent variable to split and analyze.The professional system divides it for the grass-roots staff and for the middle and high managers according to their different demand on the entity though the object-oriented classification method.May this kind of classification method and model of design thought do some guidance and reference significance for the further research on building a rounded classification system.
