AbstractProduction processes are changing the properties of substances, energy and information in terms of time, location, quantity, quality, and their interactions. The learning unit aims at developing analytical and problem solving skills that are essential in engineering sciences. Case studies are characteristic examples for timber harvesting and manufacturing.
ObjectiveProzessnetzwerke werden als Material- und Informationsflüsse auf einem Graphen abgebildet, analysiert und zielgerichtet beeinflusst. Die Studierenden sollen dabei,
• Die wissenschaftlichen Grundlagen des Systems Engineering verstehen,
• Die Fertigkeiten fuer die Anwendung und den Umgang mit Tools für die Analyse von Prozessnetzwerken und Teilsystemen zu festigen,
• Die Problemlösekompetenz vertiefen,
• Ausgewählte Themen anhand von Originalliteratur vertiefen und kritisch beurteilen.
• Die Konzepte „bestmögliche Vorgehensweise“ (best practice BP) und „beste verfügbare Technik“ (best available technology BAT) auf Exkursionen und anhand von Fallstudien verstehen.

AbstractThe lecture Wood structure and function conveys basic knowledge on the microstructure of softwoods and hardwoods as well as general and species-specific relationships between growth processes, wood properties and wood function in the living tree.
ObjectiveLearning target is a basic understanding of the anatomy of wood and the related impact of endogenous and exogenous factors. The students can learn how to distinguish common central European wood species at the macroscopic and microscopic level. A deeper insight will be given by wood identification exercises for softwood species. Further the students will gain insight into the relationships between tree growth and wood properties with a specific focus on the wood function in the living tree.
ContentIn an introduction to wood anatomy, the general structural features of softwoods and hardwoods will be explained and factors of diversity and variability will be discussed. A specific focus is laid on common central European tree species with relevance in the wood sector, which will be studied in macro-and microstructural investigations. For softwoods, exercises for the identification of species will be conducted. In the following, relationships between wood structure, properties and function in the living tree will be in the focus of the lecture. Topics covered are mechanical stability and water transport, branches, reaction wood formation (compression wood, tension wood), spiral growth, growth stresses as well as adaptive growth of trees.

AbstractThe lecture Wood processing conveys knowledge on technological properties of wood and wood-based materials as well as on industrial processes for the fabrication of a vast variety of wood products.
ObjectiveLearning target is a fundamental understanding of the dominating wood machining processes, which are applied to fabricate common wood products. Students will be introduced to the economic relevance of the renewable resource wood and are trained in its technological properties. The students will learn to identify the relationships between wood species and their properties as well as the suitable wood machining processes to fabricate targeted wood products.
ContentThe general introduction shows the economic relevance of the resource wood in a global, European and Swiss context and reflects aspects of sustainability in wood production and certification. In terms of bulk wood products a specific focus in laid on sawn timber production and drying processes. With regard to wood veneer production, steaming, veneer cutting and assembly to veneer lumber products are presented. Further the common technologies for the production of particle boards and fibre boards as well as paper will be discussed. In the following, the topics are related to wood gluing and wood protection as well as potentials and limitations in the application of wood and wood-based products. At the end of the lecture an excursion to a Swiss wood manufacturer is planned, in order to facilitate practical experience.
