| Abstract | Classical DEA assumes DMU to be homogeneous, but in fact, some researchers found that DMU always had heterogeneous character, which would result in bias of relative efficiency scores and influence discrimination power of DEA. Environment heterogeneity is one characteristic manifestation of DMU heterogeneity. With retrospect to DEA method on DMU environment heterogeneity and focus on defect of the frontier separation approach, this paper discusses DEA method of multiple environmental character variable (ECV in short) grouping and demonstrates the method regarding China road freight transportation industry (CRFTI in short), and compares the result to the classical DEA method, not considering environment heterogeneity to confirm the discrimination power. The author wishes to provide some revelation to DEA method research in DMU environment heterogeneity situation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
