  • DEAに基づく最小実現コストの改善目標設定アプローチに関する研究

    2020年  

     概要を見る

    DataEnvelopment Analysis(DEA) has been widely used as a means of relativeefficiency evaluation since the first DEA model was introduced in 1978. It uses mathematicalprogramming techniques and models to evaluate the relative efficiency of decisionmaking units(DMUs) with multiple inputs and outputs. In DEA, an inefficient DMU’sefficiency can be improved by adjusting the inputs or outputs or both to reachthe projection target on the efficient frontier. In this research, we aim atsolving the lowest cost problem in DEA, which is to provide an efficient targetfor an inefficient DMU with the lowest adjustment costs. For this purpose, anew approach based on the least distance DEA model is proposed. Here, themarginal costs of adjusting the inputs and outputs are assumed to be known andsymmetrical. For the practical merit, different with the existing studies, our approachis able to increase inputs and decrease outputs. Numerical experiments are conductedto compare the performance of the proposed approach with previous existingstudies. The results show that the proposed approach can always provide anefficient target with no higher total adjustment costs than the costs oftargets provided by previous approaches. Therefore, this research’scontributions can be summarized as follows:  • Propose an approach to DEA that minimizes the totaladjustment costs incurred when transitioning an inefficient DMU to an efficienttarget;• Enable the real world condition that some inputs couldbe increased or some outputs could be reduced to be reflected in the targetsetting process.Thus, the proposed approach is more practical and usefulfor decision makers.

     概要を見る

    Dataenvelopment analysis (DEA) introduced in 1978 has been widely applied toevaluating the relative efficiency and providing efficient target for decisionmaking units (DMUs). The conventional range adjusted measure (RAM) in DEA actsas a well-defined measure satisfying a set of desirable properties, especiallythe strong monotonicity. However, because of the practicality of the closestefficient target, we focus on formulating the least-distance range adjustedmeasure (LRAM) and proposing the use of an efficient mixed integer programming(MIP) approach to compute it. Our formulated LRAM: (1) satisfies the desirableproperties as the conventional RAM; (2) provides the least-distance benchmarkinginformation for inefficient DMUs, which will make the efficiency improvementeasy, and (3) can be computed easily by using the proposed MIP approach. Here, weapply the LRAM to a Japanese banking data set corresponding to the period 2017-2019.Based on the results: the LRAM generates higher efficiency scores and allowsinefficient banks to improve their efficiency with a smaller extent ofinput-output modification than that required by the RAM, which indicates thatthe LRAM can provide more easy-to-achieve benchmarking information for inefficientbanks. Therefore, from the perspective of the managers of DMUs, we provide a valuableLRAM for efficiency evaluation and benchmarking analysis.

  • DEAに基づく新たなベンチマーキングの手法の理論構築と実践に関する研究

    2019年  

     概要を見る

    The technique ofdata envelopment analysis (DEA) introduced by Charnes, Cooper and Rhodes (CCR)in 1978 has been widely applied to evaluating the relative efficiency ofdecision making units (DMUs). DEA provides not only efficient performance ofeach assessed DMU but also a target that improves efficiency of the DMU. Theefficient targets provided by the classical DEA models are always very far fromthe assessed DMU. However, the closest efficient target is often moreappropriate because it needs less effort to make the DMU efficient from theperspective of managers of DMUs. The difficulties of computing the closestefficient target are: (a) the definition of the efficient frontier is given inan implicit fashion, that is hard to be exploited in an algorithm; (b) theefficient frontier is nonconvex. In our research, in order to overcome thesedifficulties, we use the optimization tool (Karush-Kuhn-Tucker conditions) totransform the definition of the efficient frontier and make the definitioncomputation-friendly. The main works we have done can be summarized as follows.(1) We proposed anew approach that can provide an efficient target that is closer to theassessed DMU than that provided by the existing studies;(2) We used theproposed approach in (1) to assess the bankruptcy-based performance of Japanesebanks. Then, an early warning of the firm's financial performance and an easy-to-achieveimprovement plan for the default firm can be provided.
