Decomposition of Total Store Purchase When Purchase Payment and Inter-Purchase Time are Interdependent DONG Song-ting, ZHAO Ping, WANG Gao, LIU Rui-ming 2011, 19 (6):  92-101.  Abstract ( 2413 )   PDF (557KB) ( 2810 )   Save The assumption that single purchase payment and inter-purchase time are independent is inconsistent with real purchase behaviors.The interdependence between the two variables may be concealed by a seemingly insignificant correlation coefficient.Therefore,the decomposition of the total store purchase based on the independence assumption could not represent the real purchase pattern accurately.Based on the analysis of consumer purchase behaviors,we develop a decompositional model which takes in the interdependence between single purchase payment and inter-purchase time,and the impact of marketing efforts. Our empirical analysis shows the effectiveness and managerial implications of the model in analyzing customers'total store purchases. Related Articles | Metrics

Research on the Satisfaction Degree and Criteria Weight Obtaining for Multiple Criteria Decision Making Problem LIU Jian, LIU Si-feng, ZHOU Xian-zhong, XUE Li 2011, 19 (6):  126-132.  Abstract ( 2710 )   PDF (405KB) ( 2329 )   Save This paper mainly focuses on this situation in the Multiple Criteria Decision Making(MCDM) problems with interval number that decision makers always have a basic expectation on some criteria. Firstly,we filter off the useless alternatives and find out the useful criteria that can arrive to the basic satisfaction degree of the decision makers on all criteria.By using the useful alternatives construct a new data table and select out the best alternative from the new table.Secondly,we propose a new definition of tolerance relation for criteria value and use the tolerance degree of criteria value to obtain the criteria weights. Thirdly,we also propose a new definition for satisfaction degree of alternatives.The best alternative(s)in decision making found by the traditional ranking methods does not have an equivalence relation with the alternative(s)that have the biggest combinatorial satisfaction degree of decision makers.Finally,an interval number example shows that the method is scientific and effective as well as feasible.
