Abstract: This paper tries to use Data Envelopment Analysis (DEA) as the foundation, combining Fuzzy Comprehensive Assessment (FCA) method and Analytic Hierarchy Process (AHP), to make decisions for the project. First we use FCA method to analyze and quantize each index, then use AHP method to determine the weight of each index, use Evaluation Model of DEA Cross-efficiency to reduce the error of expert evaluation and weight in the FCA method. This paper will give the detailed steps. Finally, we use a case to test the reliability and feasibility of our method. We think, this paper will provide a now method for the Construction project bidders.

Abstract: In 2012, for the first time China implemented the toll free expressway policy for part of vehicles on major holidays. However, there is no universal compensation mechanism thereafter. How to choose the compensation basis is the core issue of establishing such a mechanism. A proper solution is to choose suitable data of listed expressway companies as the basis. Factors including corporate social responsibility and compensation theory being taken into account, listed companies with an over 95% ratio of toll operations are sifted out, and part of companies with low efficiency are wiped out by DEA Models. 5 listed companies stand out from data sieving on Annual Reports 2012. Data can serve as the compensation basis of the year.

Abstract: This study sourced the 2010 data of 25 Taiwanese life insurance companies, and conducted data envelopment analysis (DEA) to evaluate their operating efficiencies. The results can provide references for insurance companies and relevant institutions. The findings showed that there are nine DMUs with an overall efficiency of 1 under DEA at the single stage. Under DEA production efficiency evaluation, there are 15 DMUs with an overall efficiency of 1. Under second stage investment efficiency evaluation, there are 8 DMUs with an overall efficiency of 1. The management matrix diagram classifies 25 life insurance companies into four types, and suggestions are provided for each type of companies for improvements. The evaluation model of two-stage DEA can help measure operational performance and determine the different operations of each stage. The findings indicated that most companies are high product efficiency and low profit or lower product efficiency and profit than other insurance companies. The result can serve as decision references for relevant supervisory authorizes and investors, and in particular, provide reference indicators for life insurance companies, or the supervisory could modify relevant law under not affecting inventors’ benefits.

Abstract: In these days, considering the growth of knowledge about environmental protection and green issues in manufacturing, green supplier selection would be the central component in the management of supply chain. This paper intends to apply data envelopment analysis for supplier selection considering environmental merits. The suppliers’ performances with respect to criteria are not pure numbers and considered in linguistic terms according to decision makers’ opinion. To handle the subjectivity of decision makers’ assessments, fuzzy logic has been applied. A case study is done to present the application of the method.
