Abstract

Industrial product development requires close collaboration between experts of several disciplines. Misunderstandings and discussions are inevitable. An integrated visualization of discipline specific conceptual models can foster agreement between experts. This work introduces a three dimensional visualization for integrated conceptual models. Models are arranged in a common 3-D information space. Dependencies are visible and provide a means for interdisciplinary problem solving.

Abstract

This thesis proposes a product design solution based on functional elements and particularly on one of its sub-categories called engineering templates. The approach supports the development process to reach the common goals of time reduction and quality enhancement by shortening the product development times, enabling continuous information flows and capitalizing on engineering knowledge. An example based on the template of a stamping tool illustrates the influence of templates on process chain shaping and evidences their utility for the concurrent engineering concept.

Abstract

The present monograph addresses the decision problem of product concept selection. It is constructed as a multi-criteria decision model spanning the dimensions benefits, costs, opportunities and risks, while each dimension represents a decision network. To focus economic aspects target costing and activity based costing have been incorporated into the methodology. The evaluation logic is based on the analytic network process, amended and modified by the fuzzy set theory.

Abstract

Currently, companies have covered their business processes with stationary workstations while mobile business applications have limited relevance. Companies can cover their overall business processes more time-efficiently and cost-effectively when they integrate mobile users in workflows using mobile device features. The objective is a framework that can be used to model and control business applications for PLM processes using mobile device features to allow a totally new user experience.

Abstract

Time and again one reads that manufacturers deliberately design their products in such a way that they break prematurely. The victims: the customers. Many manufacturers, however, want to delay the wear. How do you go about planning for obsolescence? The book presents for the first time the view and experiences of those who develop, design and manufacture products. The contributions deal with reparability as a business model, product lifecycle management, obsolescence as a management topic, the role of state influence and the social drivers of the short-lived consumer goods.

Abstract

Due to the influence of pore-throat size distribution, pore connectivity, and microscale fractures, the transport, distribution, and residual saturation of fluids in porous media are difficult to characterize. Petrophysical methods in natural porous media have attracted great attention in a variety of fields, especially in the oil and gas industry. A wide range of research studies have been conducted on the characterization of porous media covers and multiphase flow therein. Reliable approaches for characterizing microstructure and multiphase flow in porous media are crucial in many fields, including the characterization of residual water or oil in hydrocarbon reservoirs and the long-term storage of supercritical CO2 in geological formations. This book gathers together 15 recent works to emphasize fundamental innovations in the field and novel applications of petrophysics in unconventional reservoirs, including experimental studies, numerical modeling (fractal approach), and multiphase flow modeling/simulations. The relevant stakeholders of this book are authorities and service companies working in the petroleum, subsurface water resources, air and water pollution, environmental, and biomaterial sectors.
