Piecewise Loglinear Estimation of Efficient Production Surfaces

Banker, Rajiv D.; Maindiratta, Ajay - In: Management Science 32 (1986) 1, pp. 126-135

Linear programming formulations for piecewise loglinear estimation of efficient production surfaces are derived from a set of basic properties postulated for the underlying production possibility sets. Unlike the piecewise linear model of Banker, Charnes, and Cooper (Banker R. D., A. Charnes, W....

Strict vs. Weak Ordinal Relations for Multipliers in Data Envelopment Analysis

Ali, Agha Iqbal; Cook, Wade D.; Seiford, Lawrence M. - In: Management Science 37 (1991) 6, pp. 733-738

that weak ordinal relations require a nonstandard DEA model. We also show that the case of strict ordinal relations can be … handled with the standard DEA model. These results hold for the CCR, BCC, additive, and multiplicative models and for …

An Application of Mathematical Programming to Assess Productivity in the Houston Independent School District

Bessent, A.; Bessent, W.; Kennington, J.; Reagan, B. - In: Management Science 28 (1982) 12, pp. 1355-1367

A school may be viewed as an enterprise in which the professional staff provide the operating conditions for converting quantifiable resources or inputs into pupil learning (outputs). The resources are determined by budgets, teacher assignments, and student assignments while learning is...

Divestiture of Nippon Telegraph and Telephone

Sueyoshi, Toshiyuki - In: Management Science 42 (1996) 9, pp. 1326-1351

This article discusses whether the Japanese government should break up NTT (Nippon Telegraph & Telephone) in 1995, as the U.S. federal government compelled AT&T (American Telephone & Telegram) to break itself into toll and local telephone companies in 1984. The divestiture of NTT has long been a...

Simulating Weights Restrictions in Data Envelopment Analysis by Means of Unobserved DMUs

Thanassoulis, E.; Allen, R. - In: Management Science 44 (1998) 4, pp. 586-594

Data envelopment analysis (DEA) is a method for assessing the comparative efficiencies of decision making units (e … using value judgments in DEA, based on unobserved Decision Making Units. In so doing, it opens up a whole new approach for … reflecting value judgments in DEA assessments, which can offer advantages in certain situations. …

Convex Input and Output Projections of Nonconvex Production Possibility Sets

Bogetoft, Peter; Tama, Joseph M.; Tind, Jørgen - In: Management Science 46 (2000) 6, pp. 858-869

In this paper we characterize the smallest production possibility set that contains a specified set of (input, output) combinations. In accordance with neoclassical production economics, this possibility set has convex projections into the input and output spaces (convex isoquants), and it...

Note---A Note on Including Ordinal Relations Among Multipliers in Data Envelopment Analysis

Golany, Boaz - In: Management Science 34 (1988) 8, pp. 1029-1033

Data Envelopment Analysis (DEA) evaluates the efficiency of Decision Making Units without imposing a priori weights on … the input and output dimensions involved. This Note extends DEA to situations where ordinal relations among weights … corresponding to certain dimensions exist. The extended model is reduced to the original DEA formulation where some of the input and …
