Efficiency decomposition in network data envelopment analysis: A relational model

- Chiang Kao
- Computer Science, Mathematics
- Eur. J. Oper. Res.
- 1 February 2009

Traditional studies in data envelopment analysis (DEA) view systems as a whole when measuring the efficiency, ignoring the operation of individual processes within a system. This paper builds a… Expand

Efficiency measurement for parallel production systems

- Chiang Kao
- Computer Science, Mathematics
- Eur. J. Oper. Res.
- 1 August 2009

In the real world there are systems which are composed of independent production units. The conventional data envelopment analysis (DEA) model uses the sum of the respective inputs and outputs of all… Expand

Network data envelopment analysis: A review

- Chiang Kao
- Mathematics, Computer Science
- Eur. J. Oper. Res.
- 16 November 2014

Network data envelopment analysis (DEA) concerns using the DEA technique to measure the relative efficiency of a system, taking into account its internal structure. The results are more meaningful… Expand

A fuzzy linear regression model with better explanatory power

- Chiang Kao, Chin-Lu Chyu
- Computer Science, Mathematics
- Fuzzy Sets Syst.
- 6 March 2002

Previous studies on fuzzy linear regression analysis have a common characteristic of increasing spreads for the estimated fuzzy responses as the independent variable increases its magnitude, which is… Expand

Fractional programming approach to fuzzy weighted average

- Chiang Kao, Shiang-Tai Liu
- Mathematics, Computer Science
- Fuzzy Sets Syst.
- 18 June 2001

This paper proposes a fractional programming approach to construct the membership function for fuzzy weighted average. Based on the α-cut representation of fuzzy sets and the extension principle, a… Expand

Least-squares estimates in fuzzy regression analysis

- Chiang Kao, Chin-Lu Chyu
- Mathematics, Computer Science
- Eur. J. Oper. Res.
- 16 July 2003

Abstract Regression is a very powerful methodology for forecasting, which is considered as an essential component of successful OR applications. In this paper an idea stemmed from the classical least… Expand

Efficiency measurement for network systems: IT impact on firm performance

- Chiang Kao, Shiuh-Nan Hwang
- Computer Science
- Decis. Support Syst.
- 1 February 2010

A recent development in DEA (data envelopment analysis) examines the internal structure of a system so that more information regarding sources that cause inefficiency can be obtained. This paper… Expand

Solving fuzzy transportation problems based on extension principle

- Shiang-Tai Liu, Chiang Kao
- Mathematics, Computer Science
- Eur. J. Oper. Res.
- 16 March 2004

Abstract Transportation models play an important role in logistics and supply chain management for reducing cost and improving service. This paper develops a procedure to derive the fuzzy objective… Expand

Interval efficiency measures in data envelopment analysis with imprecise data

- Chiang Kao
- Mathematics, Computer Science
- Eur. J. Oper. Res.
- 16 October 2006

The conventional data envelopment analysis (DEA) measures the relative efficiencies of a set of decision making units (DMUs) with exact values of inputs and outputs. For imprecise data, i.e.,… Expand

Fuzzy measures for correlation coefficient of fuzzy numbers

- Shiang-Tai Liu, Chiang Kao
- Mathematics, Computer Science
- Fuzzy Sets Syst.
- 1 June 2002

Correlation coefficient of random variables has wide applications in statistical analysis. This paper extends the applications to fuzzy environment, with a methodology for calculating the correlation… Expand
