Approach to business object state model evaluation for e-business information system

The United Model Language (UML) has been applied successfully in e-Business disciplines. Among UML, the state diagram is an important descriptive means to model business object state transition in e-Business information system. But it is still lack of feasible and effective validation method which can be utilized to formalize and revise the business object state diagram. In this thesis, a new approach for this problem is proposed based on the polychromatic set theory. Based on this theory, it can realize the mapping from this model to the PS contour matrix of the polychromatic set, and implements the effective model revision and the improvement. Firstly, the transformation method from business object state diagram to contour matrix model of polychromatic sets was established. Combinations of any two states were recognized as the elements of polychromatic sets, and the connection relationships between any two business object states were recognized as the contour of polychromatic sets. Secondly, the evaluation and reduction algorithm of the business object state model was presented. Finally, an example of software requirement state transformation diagram was provided for applications of the theory and method mentioned above. As a result, the requirement state model can be optimized and evaluated quantitatively. The new approach is feasible and effective.
