摘要
In General, the precision degree of the system coding process would highly influence the quality of decision making. For complex and obscure business systems, the rough set theory provides excellent performances on dealing with implicit data and ambiguity information, and shows validity on simplifying the decision making procedure. However, most of recent researches focus on applications of different systems and fields, and specific discussions on the accuracy of approximation and the decision boundary are few. Therefore, this paper would deduce a new scenario on decision making analysis for discrete coded systems, and using the second-order norm (2nd norm / Euclidean norm) to define the perturbation rate and the perturbation ratio of the new decision that could demonstrates where the decision boundary would be! As regards in practice, the measure of quality is not an exact science. Therefore, the concluded result of this research would utilize the e-TransQual model that was developed by Bauer et al. (2006) to verify the whole process. The upgrading decision of on-line shopping stores was recognized as the controllable variable, and it would be necessary to satisfy decision algorithms of the original information system. The difference between the old and the new decisions would be represented by the Euclidean norm as the "distance" (one-dimension measurement), and further discussions on the perturbation condition of the new decision would be introduced. Finding the possible boundary of the new decision for the original system would be carefully checked, and the advantages and the disadvantages of the new decision-making process of the rough set theory would be verified.
