In design, manufacturing and usage of technical products uncertainty arises according to process properties and results in influence of products properties. In current CAD-systems, where products and product properties are presented, uncertainty is not considered yet. In this paper, we propose a new enhanced concept for the visualization of information about uncertainty in CAD-systems. The presentation of uncertainty is realized on basis of three-dimensional parametric models in a CAD-system and an implemented uncertainty-browser. The uncertainty-browser acts as a graphical user interface to categorize information about uncertainty, the processes and product properties. Beyond that, information about uncertainty will be visualized as annotations referring to chosen properties. Being aware of information about uncertainty during product design, the engineer is able to improve his product. The representation of uncertainty is based on an ontology based information system for supporting the collection and categorization of information about processes, products and uncertainty.

There is a growing trend in many industries to expand the diversity of product offerings to meet widespread customer needs. This trend has increased the need for flexibility in manufacturing processes. Advances in flexible automation have far outpaced the research supporting flexibility in the manual operations that are required alongside automation. The objective of this study was to test a real-time computer support system that provided interactive assembly instructions through a graphical user interface combining text and illustration for workers on a flexible assembly line. The interface simplifies the expertise required of an assembly worker by replacing complex blueprints with simple directions and illustrations, thus supporting the rapid introduction of new products and the assembly of a wide variety of parts with minimal off-line training. The results of the study strongly support the use of this type of system. Assembly times were significantly reduced, in most cases by over 50%. Furthermore, assembly errors were virtually eliminated.

WOFOST version 7.1.3 is a computer model that simulates the growth and production of annual field crops. All the run options are operational through a graphical user interface named WOFOST Control Center version 1.8 (WCC). WCC facilitates selecting the production level, and input data sets on crop, soil, weather, crop calendar, hydrological field conditions, soil fertility parameters and the output options. The files with crop, soil and weather data are explained, as well as the run files and the output files. A general overview is given of the development and the applications of the model. Its underlying concepts are discussed briefly.
