Quantitative Models for Performance Evaluation and Benchmarking: Data Envelopment Analysis (International Series ... in Operations Research & Management Science) (Hardcover)
by Joe Zhu 

It is difficult to evaluate an organization's performance when there are multiple inputs and multiple outputs to the system. The difficulties are further enhanced when the relationships between the inputs and the outputs are complex and involve unknown tradeoffs. This book introduces DEA as a multiple-measure performance evaluation and benchmarking tool. The focus of performance evaluation and benchmarking is shifted from characterizing performance in terms of single measures to evaluating performance as a multidimensional systems perspective. New DEA models and approaches are presented to deal with performance evaluation problems in a variety of contexts. A context-dependent DEA measures the relative attractiveness of similar operations/processes/products. Sensitivity analysis techniques can be easily applied and used to identify critical performance measures. Value chain efficiency models and DEA benchmarking models can be utilized to study...DATA ENVELOPMENT ANALYSIS  Read more

Motivates DEA as a new approach to organizing and analyzing data beyond its origin in efficiency analyses; 
Presents an integrated framework, and standardized notation for understanding basic DEA models and their extension; 
Develops a deeper understanding of computational issues involved in solving various DEA formulations; 
Provides insights into the DEA process, its usage and interpretations; 
Highlights the range of potential uses of DEA through examples of novel applications; 
Provides an updated comprehensive bibliography; 
Facilitates the diffusion of DEA by making Chapters 1--4 and 21 available for inclusion in operations research, econometric and statistic textbooks under normal provisions which maintain original copyright status. DATA ENVELOPMENT ANALYSIS  Read more

 

 

Dynamics of Data Envelopment Analysis : Theory of Systems Efficiency (Hardcover)
by J.K. Sengupta 

The volume extends the recent techniques of data envelopment analysis in dynamic and stochastic fields. Its outstanding features are: (1) a comprehensive and up-to-date treatment of productive efficiency analysis in the dynamic environment; (2) new insight into the stochastic aspects of efficiency analysis including modern control theory; and, (3) new applications in systems theory including flexible manufacturing systems. New results and applications are stressed in (1) new growth theory in economics, (2) new time series models and (3) the recent models of technological diffusion. 
Audience: The latest tools of efficiency analysis developed in this book, illustrated by numerous real life applications, are most suitable for graduate students and researchers in operations research, management science and applied econometrics. DATA ENVELOPMENT ANALYSIS  Read more

Analysis of the  quality-price ratio obtained by cars sold on market

Technique "KonSi-DEA Analysis" is applied to analysis of a performance-price-ratio obtained by cars under consideration. Each car is assessed as a bundle of qualitative and quantitative characteristics which create utility for the consumer. All characteristics are divided into inputs and outputs. The inputs are price and running costs. The outputs are engine power, comfort, special equipment, brand strength etc.

DATA ENVELOPMENT ANALYSIS KonSi DEA Analysis allows you to take account of all the important factors that affect a units performance to provide a complete and comprehensive assessment of efficiency. KonSi DEA Analysis does it by converting multiple inputs and outputs into a single measure of productive efficiency. By doing so it identifies those units, which are operating relatively efficiently and those which are not. The efficient units, which are making the best use of resources, are rated as being 100% efficient whilst the inefficient ones obtain lower scores.
