Due to stochasticity in the system behavior, the data obtained for identification can be considered as one realization of the underlying stochastic phenomenon. In order to effectively deal with the identification of such systems, it may be advantageous to repeat the identification experiment multiple times under similar conditions. The multiple input-output time series generated in this way thus contain information about stochastic variations within the system. This paper presents one of the possible approaches to effectively deal with identification in such scenario in the framework of Nonlinear Output Error (NOE) Takagi-Sugeno (TS) fuzzy models. Based on extended Chebyshev's inequality for finite samples, the lower and upper boundaries of the output time-series are obtained using (1-$\alpha$) confidence interval (envelops of the response). The proposed identification algorithm provides a model for predicting the most likely value as well as the boundary models for predicting the envelops of the output signal.

Moreover, the impact of mutation operators (swap, insertion, inversion, displacement, and their various combinations) is analyzed when solving several industrial plant inspection problems. The experimental results show that: (1) the proposed genetic algorithm can obtain better solutions than the tested binary tournament genetic algorithm with partially mapped crossover; (2) inversion mutation performs better than other tested mutation operators when solving problems without cooperative tasks, and the swap-inversion combination performs better than other tested mutation operators/combinations when solving problems with cooperative tasks.

Dabei ist die Inspektionstätigkeit zumeist monoton und ermüdend. Die hohen Anschaffungskosten, die notwendige umfangreiche Einarbeitung in die Bedienung, die niedrige Auslastung bei manueller Verwendung sowie das schwer quantifizierbare Einsparungspotential schrecken oft von der Beschaffung von Fernmessgeräten ab. Ziel des Projektes RoboGasInspector ist die Entwicklung eines mobilen, mit infrarotoptischer Fernmesstechnik ausgestatteten professionellen Service-Roboters für die Routineinspektion von Industrieanlagen. Durch den Einsatz auf einem Roboter kann die Messtechnik voll ausgelastet werden, da dieser rund um die Uhr im Betrieb sein kann. Der Mensch wird von eintöniger Arbeit entlastet und das Fachpersonal steht für anspruchsvollere Aufgaben zur Verfügung. Die Reproduzierbarkeit der Ergebnisse wird verbessert und lässt zudem eine präzisere Differentialdiagnose mit historischen Daten zu; dadurch kann auch der Schädigungsverlauf dokumentiert werden. Durch die Verwendung von Messgeräten mit verschiedenen Messprinzipien kann eine Leckhypothese abgesichert und die Wahrscheinlichkeit von Falschalarmen reduziert werden.

Furthermore, the approach is compared and graphically illustrated with other alternate approaches on the basis of interval data and interval membership functions. Assuming the identification method can be repeated offline a number of times under similar conditions, multiple input -- output time series can be obtained from the underlying system. These time series are pre-processed using the techniques of statistics and probability theory to generate the envelopes of response (curves outlining the upper and lower extremes of response) at each time instant. Two types of envelopes are described in this research: the max -- min envelopes and the envelopes based on the confidence intervals provided by extended Chebyshev's inequality. By incorporating interval data in fuzzy modelling and using the theory of symbolic interval-valued data, a TS fuzzy model with interval antecedent and consequent parameters is obtained. This algorithm provides a model for predicting the expected response as well as envelopes. In order to validate the presented model, a simulation case study is devised in this paper.
