Journal ArticleDOI
TL;DR: In this paper, a new multiplicative efficiency formulation is developed wherein the efficiency values are invariant under changes in the units of measurement of outputs and inputs, and it is shown that the associated Data Envelopment Analysis (DEA) implies that optimal envelopments are of piecewise Cobb-Douglas type.

TL;DR: A new application of DEA (Data Envelopment Analysis) is examined for evaluating the efficiency of occupational-technical programs in a comprehensive community college.
Abstract: A new application of DEA (Data Envelopment Analysis) is examined for evaluating the efficiency of occupational-technicalprograms in a comprehensive community college. This includes extensions of DEA for use in evaluating new programs that might be introduced along with possible combinations of old programs. Emphasis is placed on the relative efficiency aspects of DEA so that consequences for the efficiency ofprograms other than those being considered can be taken into account. Uses by the director of San Antonio College are described and placed in a context of the other elements that entered into her decisions. In conclusion, possible further improvements in DEA are discussed along with the kinds of research needed to achieve them.

TL;DR: It is shown that the analysis of a very simple artificial example contrived by its authors for a general indictment of all chance constrained programming is itself in error.
Abstract: Once again we show that the analysis of a very simple artificial example contrived by its authors for a general indictment of all chance constrained programming is itself in error. Proofs and further references are supplied below along with a discussion of other deficiencies and ambiguities in an article authored by A. J. Hogan, J. G. Morris and H. E. Thompson in Management Science, Vol. 27, No. 6 June 1981.

TL;DR: In this paper, the construction and analysis of Pareto-optimal frontier production functions by a new Data Envelopment Analysis method is developed in the context of new theoretical characterizations of the inherent structure and capabilities of such empirical production functions.
Abstract: : The construction and analysis of Pareto-optimal frontier production functions by a new Data Envelopment Analysis method is developed in the context of new theoretical characterizations of the inherent structure and capabilities of such empirical production functions. Contrasts and connections with other developments, including solutions of some remaining problems, are made re aspects such as informatics, economies of scale, isotonicity and non-concavity, discretionary and nondiscretionary inputs, piecewise linearity, partial derivatives and Cobb-Douglas properties of the functions. Non-Archimedean constructs are not required. (Author)
