In some companies, undesirable costs are imposed for provision of services. It is required that current outputs of decision making units are produced at minimal undesirable cost. In this paper, a new method is proposed for evaluating the undesirable cost imposed on the units. Moreover, data is considered in fuzzy number form, due to the observed input-output data are sometimes imprecise in real...

The purpose of this contribution1 is to set up a language to evaluate the results of concerted action among interdependent agents against predetermined properties that we can recognise as desirable from a deontic point of view. Unlike the standard view of logics to reason about coalitionally rational action, the capacity of a set of agents to take a rational decision will be restricted to what ...

The use of Brzier curves or Brzier surfaces as "faired" interpolation (approximation) curves or surfaces occasionally yields inflection points or changes of sign of the Gaussian curvature which are undesirable in some applications, notably the fairing of ship lines (surfaces) or the fairing of car body surfaces. In the following investigation we use a polarity to detect such undesirable points,...

This article reports the findings of an experiment designed to evaluate the effect of four questionnaire formats on the willingness of drivers convicted of drunken driving to admit to this socially undesirable behaviour. Four samples of convicted drunk drivers each received a different version of a mail questionnaire about driving behaviour and attitudes. Two versions of the questionnaire inclu...

Causality violations are typically seen as unrealistic and undesirable features of a physical model. The following points out three reasons why causal-ity violations, which Bonnor and Steadman identified even in solutions to the Ein-stein equation referring to ordinary laboratory situations, are not necessarily undesirable. First, a space-time in which every causal curve can be extended into a ...

Power transformers are still among the most costly and critical components in an electrical power network. Thus, the importance of a reliable condition assessment of these assets increases due to the aging of transformer fleets. The Sweep Frequency Response Analysis (SFRA) has become an important standard test and provides comprehensive information about the mechanical and electrical integrity ...

Very often children with learning difficulties show undesirable forms of behavior, which means any of the forms of behavior considered by the society to be striking and unacceptable, or in other words, those which disturb or hinder the process of education and rehabilitation. The objective of this research was to examine the possibilities of applying integrative therapy in the treatment of ment...
