The paper concerns the use of alternative and/or combined methodologies (Data Envelopment Analysis, Regression Analysis, Goal Programming) as a means of ascertaining the efficiency as well as the efficient marginal costs of outputs of homogeneous organizational units. The same body of data is used throughout the analysis and the results derived from the combination of Data Envelopment Analysis and Goal Programming are shown to be more reliable than those obtained by the other methods. 相似文献

This paper is devoted to Idempotent Functional Analysis, which is an abstract version of Idempotent Analysis developed by V. P. Maslov and his collaborators. We give a brief survey of the basic ideas of Idempotent Analysis. The correspondence between concepts and theorems of traditional Functional Analysis and its idempotent version is discussed in the spirit of N. Bohr's correspondence principle in quantum theory. We present an algebraic approach to Idempotent Functional Analysis. Basic notions and results are formulated in algebraic terms; the essential point is that the operation of idempotent addition can be defined for arbitrary infinite sets of summands. We study idempotent analogs of the basic principles of linear functional analysis and results on the general form of a linear functional and scalar products in idempotent spaces. 相似文献

Benefits Analysis has been evolving over the past decade from roots in multi-criteria analysis, causal mapping and multi-methodology. It has now reached a level of maturity such that it deserves to be treated as a method in its own right, and this paper seeks to document the method and provide guidance on its use. Benefits Analysis is a systematic method for formulating complex, multi-factor investment appraisal problems where decision-makers seek to realize non-financial benefits. Such decision problems abound in military OR, particularly the management of equipment capability and research. Benefits Analysis connects qualitative and quantitative OR methods and facilitates robust assessment, including multi-methodology. This paper describes the principles of Benefits Analysis and discusses its application to a variety of real problems, including research management, capability management, balance of investment, business case development and benefit quantification strategies. 相似文献

Variational Analysis studies mathematical objects under small variations. With regards to optimization, these objects are typified by representations of first-order or second-order information (gradients, subgradients, Hessians, etc). On the other hand, Derivative-Free Optimization studies algorithms for continuous optimization that do not use first-order information. As such, researchers might conclude that Variational Analysis plays a limited role in Derivative-Free Optimization research. In this paper we argue the contrary by showing that many successful DFO algorithms rely heavily on tools and results from Variational Analysis.

This article identifies differences and similarities between DEA (Data Envelopment Analysis) and DA (Discriminant Analysis) in the view of GP (Goal Programming). Based upon such characterization, this article proposes a new type of DA technique, referred to as “DEA-Discriminant Analysis (DEA-DA)”, that incorporates a methodological strength of DEA into the DA formulation. This research applies the proposed DEA-DA method to both an illustrative data set and a real case study related to Japanese banks. The importance of DEA-DA is confirmed by comparing it with other DA methods. 相似文献

We present in this paper a short survey of some recent interactions between Nonlinear Analysis and Nonlinear Complementarity.
Considering the new relations between Nonlinear Analysis and Complementarity Theory, put in evidence in this paper, we define
several open research subjects profitable to both domains. 相似文献

At the University of Louisville, a large, urban institution in the south-east United States, undergraduate engineering students take their mathematics courses from the school of engineering. In the fall of their freshman year, engineering students take Engineering Analysis I, a calculus-based engineering analysis course. After the first two weeks of the semester, many students end up leaving Engineering Analysis I and moving to a mathematics intervention course. In an effort to retain more students in Engineering Analysis I, the department collaborated with university academic support services to create a summer intervention programme. Students were targeted for the summer programme based on their score on an algebra readiness exam (ARE). In a previous study, the ARE scores were found to be a significant predictor of retention and performance in Engineering Analysis I. This study continues that work, analysing data from students who entered the engineering school in the fall of 2012. The predictive validity of the ARE was verified, and a hierarchical linear regression model was created using math American College Testing (ACT) scores, ARE scores, summer intervention participation, and several metacognitive and motivational factors as measured by subscales of the Motivated Strategies for Learning Questionnaire. In the regression model, ARE score explained an additional 5.1% of the variation in exam performance in Engineering Analysis I beyond math ACT score. Students took the ARE before and after the summer interventions and scores were significantly higher following the intervention. However, intervention participants nonetheless had lower exam scores in Engineering Analysis I. The following factors related to motivation and learning strategies were found to significantly predict exam scores in Engineering Analysis I: time and study environment management, internal goal orientation, and test anxiety. The adjusted R2 for the full model was 0.42, meaning that the model could explain 42% of the variation in Engineering Analysis I exam scores. 相似文献

We introduce the Linear Relative Canonical Analysis (LRCA) of Euclidean random variables. Then similar properties than for
usual linear Canonical Analysis are obtained. Furthermore, we develop an asymptotic study of LRCA and apply the obtained results
to tests for lack of relative linear association, dimensionality and invariance. 相似文献
