Abstract | Data Envelopment Analysis (DEA) is a kind of comprehensive evaluation method to rank and calculate the corresponding efficiency for each Decision Making Unit (DMU) by constructing a production frontier in multiple inputs and outputs system. For each DMU, we can use multiple variables to describe the characters of DMU, which can be classified as input variables and output variables separately. In traditional DEA models, we needn't do any transformation for input and output variables when we apply DEA into evaluation procedure because the linear programming can allocate optimal weights for different variables based on the principle of the lower inputs and higher outputs the better. However, traditional DEA models can obtain weak evaluation results that most of DMUs are efficient when each DMU has large amount input variables and output variables. To overcome the shortcoming of DEA models, we proposed an integrated DEA model, denoted as PCA-DEA, in this paper. By using CPA arithmetic, the original data for each DMU can be transferred into uncorrelated data. Then, CPA-DEA models have stronger evaluation capability than traditional DEA models. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
