To Improve And Applied Research Of Matrix Of The Input And Output DEA Model

Complex patterns of input and output of DEA efficiency evaluation has been at theforefront of DEA theory research. In many practice study, because of the complexity of thesystem, at the same time, because people on the system unit index observation, there are a lotof subjective measurement error and system error, which makes ordinary DEA method ofefficiency evaluation by the larger interference. People tend to focus on the recent information,according to their own knowledge and experience in traditional DEA methods to gain theefficiency of the system unit value, and rarely consider the effect of previous data informationlag. This evaluation of the results did not make full use of the value of the data, and makes theconclusion that the lack of convincing. Multiple times (multiple layers), for example, theinput and output of the system, people rarely consider the effect of previous information. Thisregard, less involved in the study of DEA theory. In this paper, it is from this Angleinformation of each period (stages or levels) of system unit is a comparative effectiveness.First of all, the author combined with the background of the research at home andabroad, browse the recent literature, and systematically combines both at home and abroad onresearch progress in the DEA theory, model and method. At the same time, the complexsystem presented in this paper the input and output model of efficiency evaluation problem, inthis kind of system circumstances, and targeted for this situation be discussed, thus theconcept of input and output matrix model was given.Secondly, the author in view of the complex form of input and output into the improvedDEA model, and combining the existing theory and method of data envelopment analysis(DEA), and made theoretical arguments for the improved model. At the same time, also incomplex condition under the line of the input and output mode improved model of solvingprocess be discussed.Finally, after fully prove that the principle of the improved model in theory, through theimproved model of14listed commercial Banks in our country has carried on the empiricalresearch. Case combining multiple inter-temporal data information to carry on thecomprehensive evaluation, through calculation and draw the different unit weight value oftime, from the weight value known to to attain the optimal proportion of efficiency value, soas to give decision makers on the other side of the reference value.
