This paper presents a conceptual approach for decision support applied in a collaborative complex system design project. The approach takes advantage of the use of Similarity-based Formal Concept Analysis (SFCA) to classify, visualize, and explore simulation data in order to help system designers to identify relevant design choices. The approach is illustrated on an aircraft cabin design case s...

At the end of the last century, Population and Development Review (PDR) published an article with the visionary title “Demographic dimensions in forecasting: adding education to age and sex” (Lutz et al. 1999). In this contribution the authors (W. Lutz, A. Goujon and G. Doblhammer-Reiter) systematically discuss the criteria governing the choice of particular dimensions (i.e. covariates, breakdo...

This paper discusses the experimental investigation to find out the optimal electrolyte composition in improving the surface quality of the gear teeth profile during surfacing finishing of bevel gears by the electrochemical honing process. In this study, AISI 1040 was used as the workpiece material, mixtures of sodium chloride and sodium nitrate in different ratios were used as the input parame...
