Measurement results contain different kinds of uncertainty. Besides systematic errors andrandom errors individual measurement results are also subject to another type of uncertainty,so-called emph{fuzziness}. It turns out that special fuzzy subsets of the set of real numbers $RR$are useful to model fuzziness of measurement results. These fuzzy subsets $x^*$ are called emph{fuzzy numbers}. The m...

In this paper we present an approach to designing a novel type of fuzzy controller B spline basis functions are used for input variables and fuzzy singletons for output variables to specify linguistic terms Product is chosen as the fuzzy conjunction and centroid as the defuzzi ca tion method By appropriately designing the rule base a fuzzy controller can be interpreted as a B spline interpolato...

This paper presents a fuzzy extension of the simple assembly line balancing problem of type 2 (SALBP-2) with fuzzy job processing times since uncertainty, variability, and imprecision are often occurred in real-world production systems. The jobs processing times are formulated by triangular fuzzy membership functions. The total fuzzy cost function is formulated as the weighted-sum of two bi-cri...

Der vorliegende Beitrag systematisiert die Möglichkeiten für die Inanspruchnahme und die Bereitstellung von Dienstleistungen im Fokus von Open-Source-Software. Die zunehmend festzustellende Konvergenz kommerzieller und Open-Source basierter Produkte lässt den Ruf nach einer ökonomischen Betrachtung in Fachkreisen lauter werden. Dieser Beitrag soll Finanzierungsalternativen und daraus hergeleite...

We deal with the constrained fuzzy arithmetic as introduced by G.J. Klir. Its implementation represents a problem because maxima of nonlinear functions have to be found. This increases the complexity of computations in comparison to the classical calculus of fuzzy quantities. We suggest a modi ed computational procedure which allows to calculate a suboptimal (i.e., inexact) solution with an acc...
