The purpose of this paper is to quantify the efficiency with which Taiwan universities utilize their teaching and scale resources. The study estimates the cost efficiency of 46 universities over the period 2001-2003 with 5 input and 4 output using data envelopment analysis (DEA). The present study differs from previous cost and efficiency studies of Taiwan universities in three ways. First, it discusses the scale (land square) in the performance. Second, it considers the combination policy of recent year in Taiwan. The last, this paper is using Malmquist index of 3 years data, which is less discussed in Taiwan. The results show that Taiwan universities have a bad performance in the scale efficiency, and land square of universities do effect the performance, but the location in Taiwan does not. And the established year also does not effect the performance. Second, many private universities have better performance in the technical efficiency from VRS DEA, but the newly established universities do not have scale efficiency very well. Third, compare Taiwan universities with the University of Tsukuba, only National Tsing Hua University can contend with.

In this essay, we use two stage data envelopment analysis (Two-stage DEA) with an application to evaluate the efficiency of six teams from Chinese Professional Baseball League (CPBL) during 2004 to 2005. In the essay, we use three methods to develop the research. First, we use the Window Analysis based on fewer DMUs situation. Second, the modification across different period has been made by Malmquist Index Analysis. Last one is Cross Efficiency; we use it for ranking efficiency performance for those teams during 2004 to 2005. According to above methods, it shows that: 1. the efficiency performance of Brother Elephants, Sinon Bulls, Chinatrust Whales, Uni Lions in the management stage is better than it in the production stage, vice versa Macoto Cobras and La new Bears in the production stage is better than management stage. 2. Each team is over optimal scale in the production stage during 2004 to 2005. 3. The result of overall performance during is shown as following place: Bulls, Elephants, Lions, Cobras, Whales, Bears; the orders in production stage are Cobras, Whales, Bulls, Bears, Elephants, Lions; the orders in management stage are Elephants, Bulls, Lions, Cobras, Bears, Whales. 4. The Malmquist Productivity Index across different period each year indicates that only La new Bears reach 4.7% according average growth rate.

Abstract After our country joins WTO, will face the strong capital competition pressure of the international large-scale financial institution, and after foreign businessman's bank has grand capital, the industry manages completely dark, in the face of so strong impact country the financial market fluctuates and aggravates, has increased the operation pressure of the domestic banking, too. How to transform this pressure into helping hand, utilize aquistion and merger to consider complementarily , lower costs then improve the competitiveness, it is really the question which the banking of Taiwan needs to face at present. Domestic aquistion and merger case or makes up the financial domain that the financial holding company has already affected 14 financial holding companies in Taiwan to reform with the operation pattern jointly at present, but these financial holding companies can reach the value expected and comprehensive result which is greater than two of one plus one ( Synergy ) The goal needs checking and tests directly. It does not belong to the financial holding company at home to spy on put the independent bank, in case of financial market saturation, the profit shrinks, the income reduces by a wide margin, the quality of the assets is not good, so that is it put rate is it wait for numerous unfavourable factor to remain high to exceed, how face assets huge financial holding company lay big bank create life their extremely, whether it is influenced that purpose calls it and manages the performance; Establish financial holding company purpose is it can reach category economy and purpose of the large-scale production to call separately. Purpose of this research, focus on wanting to untie it under the trend of the international finance, can really improve the bank and manage the performance and business efficiency of independent bank to establish the financial holding company under the double pressure of the domestic trouble and foreign invasion and really not so good as finance holding company bank put. Because of above-mentioned backgrounds and motives, so this text hope book probe into by document, materials collect and utilize materials not to make analytic approach of holding in place with a net ( Data Envelopment Analysis , abbreviated as DEA) ,displaying the result of study, it is by offering competent authorities or the financial holding company policymaker to the government and wanting to set up some reference suggestions of bank of the financial holding company. Keywords: Data Envelopment Analysis , The materials charter and hold analytic approach, technological efficiency, pure technological efficiency, scale efficiency

ABSTRACT A DEA-BASED APPROACH TO RANKING MULTI-CRITERIA ALTERNATIVES Tuncer, Ceren M.Sc., Department of Industrial Engineering Supervisor: Prof. Dr. Murat K&ouml / ksalan August 2006, 88 pages This thesis addresses the problem of ranking multi-criteria alternatives. A Data Envelopment Analysis (DEA)-based approach, the Method of the Area of the Efficiency Score Graph (AES) is proposed. Rather than assessing the alternatives with respect to the fixed original alternative set as done in the existing DEA-based ranking methods, AES considers the change in the efficiency scores of the alternatives while reducing the size of the alternative set. Producing a final score for each alternative that accounts for the progress of its efficiency score, AES favors alternatives that manage to improve quickly and maintain high levels of efficiency. The preferences of the Decision Maker (DM) are incorporated into the analysis in the form of weight restrictions. The utilization of the AES scores of the alternatives in an incremental clustering algorithm is also proposed. The AES Method is applied to rank MBA programs worldwide, sorting of the programs is also performed using their AES scores. Results are compared to another DEA-based ranking method. Keywords: Ranking, data envelopment analysis, weight restrictions.

In this study two different hybrid ranking approaches based on data envelopment analysis and outranking relations for ranking alternatives are proposed. Outranking relations are widely used in Multicriteria Decision Making (MCDM) for ranking the alternatives and appropriate in situations when we have limited information on the preference structure of the decision maker. Yet to apply these methods DM should provide exact values for method parameters (weights, thresholds etc.) as well as basic information such as alternative scores. DEA is used for classification of decision making units according to their efficiency scores in a non-parameteric way. The proposed hybrid approaches utilize PROMETHEE (a well known method based on outranking relations) to construct outranking relations by pairwise comparisons and a technique similar to DEA crossefficiency ranking for aggregating comparisons. While first of the proposed approaches can deal with imprecise specification of criterion weights, second approach can utilize imprecise weights and thresholds.

The history of natural gas in Turkey started in 1970s by the usage of domestic gas in cement factories. However, natural gas began penetrating the energy market in 1980s with the usage of natural gas in Ankara. In the following years, the number of cities using natural gas reached six. Then, a new era started with the enactment of Natural Gas Market Law in 2001 and 53 distribution tenders have been realized by Energy Market Regulatory Authority until 2009. This thesis analyzes the performance of 38 Turkish natural gas distribution companies by using a non-parametric method, Data Envelopment Analysis. The results are used to determine the most proper model specification, to detect the important criteria affecting the efficiency levels and to find the common characteristics of the most inefficient firms. The results show that public firms compared to private firms, non-tender firms compared to tender firms, large firms compared to small firms and firms operating in more developed areas compared to firms operating in underdeveloped areas utilize resources and manage costs more efficiently. However, we can not get a certain conclusion about the comparison of old firms and new firms. Lastly, we try to detect the common characteristics of the most inefficient firms and find that the major problem is low delivery amount.

<p>This paper offers to measure efficiency of banks in Sub Saharan Africa and its determining input andout put factors on two fonts. At this purpose, we applied the first font; Data Envelopment Analysis(DEA) for assessing efficiency level. The actual and target level of inputs/outputs to foster efficiencyare shown in the results. Secondly, the banks ratio analysis measuring banks performance throughreturns volatility for each bank, asset utilization and provision for bad and doubtful debts over thestudy period are all used as tools for this analysis. Our results suggest that Sub Saharan AfricanBanks are about 98.35% efficient. We are aware that the level of efficiency could be subject to up anddown swing if environmental factors influencing banks efficiency where taken into consideration.Finally, our result (DEA) is more sensitive to loans, other liabilities, other non interest expense,securities and deposit.</p>

In January 2007, the Gulf of Mexico red snapper fishery took a step toward sustainability and began management under an individual fishing quota (IFQ) system. The hope is that direct ownership stakes by fishers brings more direct involvement on behalf of the boat owners and fishermen as well as more responsible and sustainable fishing practices on depressed fish populations. The research was conducted in order to study the welfare of local fishing communities as well as the effects on the red snapper fishery itself. Traditional fisheries and economic data were analyzed. In addition a Data Envelopment Analysis (DEA) of the Florida Gulf Coast communities involved in the red snapper fishery was performed to compare to the analysis of fishing communities prepared by the National Marine Fisheries Service (NMFS). Finally, online and phone surveys of fishermen involved in the red snapper fishery were performed to gauge their responses to the change in management. The study reveals a strong correlation between the DEA analysis of fishing communities affected and the analysis performed by NMFS, and reinforces DEA as a method of determining involvement in a fishery. Additionally, the thesis indicates the red snapper IFQ has performed as expected in some areas by its supporters – an average gulf-wide ex-vessel price per pound increase of 10% in just three years; elimination of the rush to fish due to guaranteed quota; and a shift in fleet composition as the number of share owners owning less than 2.00% have dwindled, and the number of shareholders possessing greater than 2.00% of the quota has increased gulf-wide by 50%. However, in other areas such as effort reduction and bycatch rates, the IFQ appears to have mixed results. A reported decline in effort is likely attributable to a reduction in the overall gulf-wide red snapper quota between 2007 and 2008 rather than the IFQ, and even NMFS doubts the bycatch data that are being reported by fishermen. Most importantly, current IFQ shareholders were surveyed via phone and internet revealing not only an overall disapproval by most fishers of the IFQ design process, but also effects contrary to those publicized by IFQ supporters, and a general distrust in fisheries management.
