| 1 | Fuzzy data envelopment analysis approach based on sample decision making units显示文摘The conventional data envelopment analysis(DEA) measures the relative efficiencies of a set of decision making units with exact values of inputs and outputs.In real-world problems,however,inputs and outputs typically have some levels of fuzziness.To analyze a decision making unit(DMU) with fuzzy input/output data,previous studies provided the fuzzy DEA model and proposed an associated evaluating approach.Nonetheless,numerous deficiencies must still be improved,including the αcut approaches,types of fuzzy numbers,and ranking techniques.Moreover,a fuzzy sample DMU still cannot be evaluated for the Fuzzy DEA model.Therefore,this paper proposes a fuzzy DEA model based on sample decision making unit(FSDEA).Five evaluation approaches and the related algorithm and ranking methods are provided to test the fuzzy sample DMU of the FSDEA model.A numerical experiment is used to demonstrate and compare the results with those obtained using alternative approaches. | Muren Zhanxin Ma Wei Cui | 2012 | Journal of Systems Engineering and Electronics2012，23，3： | 11 |
| 2 | Cooperation and Competition Strategy Analysis of Decision-Making Units Based on Efficiency Game显示文摘Data envelopment analysis(DEA)method based on game theory effectively ranks the decisionmaking units(DMUs)by the view of cooperation or competition.The DEA method based on partial ordered set theory depicts the relationships among DMUs.However,these methods are unable to reveal the complex cooperation and competition relationships among DMUs.In this paper,an optimal model for DMU group game strategy is proposed based on the generalized DEA method and game theory.According to this model,we can effectively depict the efficiency change of DMUs.Moreover,the effect of various game relationships on individual and the union of DMUs can be characterized.It is of positive significance for decision makers to find partners and moderate the cooperation and competition situation of their competitors.Finally,the cooperation and competition relationships of 9 express enterprises in a certain area in China are analyzed by using the method proposed in this paper. | Li Cao Zhanxin Ma Muren | 2020 | Journal of Systems Science and Systems Engineering2020，29，2： | 4 |
