08 Déc Dealing with risks – old and new challenges

Swiss Academy of Engineering Sciences (SATW)
December 2016
Authors: Wolfgang Kröger et al. Main themes: risk Nature of publication: white paper The term risk still varies in its scope, and depending on the relevant community may be limited to the consequences of an undesired event or may also include positive aspects and opportunities. There is no universal definition, while the key elements of risk – in particular “probability” and its interplay with other elements – are frequently poorly understood. We are often left perplexed by residual uncertainties which may result from a lack of knowledge or the inherent randomness of events (take earthquake as an example), with the same going for the handling of residual risk. The simple risk concept with a multiplicative combination of frequency and consequence is often considered inappropriate for events with a high level of damage (despite their admitted rarity), asserting aversion to risk – as is for example common in the nuclear sector. These challenges (some old, some new) and touted opportunities were the subject of a workshop in November 2013. The aim of this white paper is to present a collection of selected articles to interested parties.

08 Sep Decentralised power production needs decentralised storage

Swiss Academy of Engineering Sciences (SATW)
September 2016
Authors: Theodor Borsche, Andreas Ulbig, Göran Andersson Main themes: energy, storage Nature of publication: study Power production in Switzerland is changing. End customers, previously consumers of centrally produced power, are themselves becoming local power producers and storing power for their own needs. In addition to central production in large power stations, there is an increasing number of small power stations producing their own power, in particular using photovoltaic systems. Power generation from new renewable energy sources is not constant or easily predictable. This unusual situation causes problems for network operators. These can be easily technically remedied by furnishing decentralised power production with local storage, but decentralised storage can also be used by a network operator for other tasks: how economic this storage is depending on the tasks which it is able to undertake. SATW commissioned the Power Systems Laboratory at ETH Zürich to investigate how and for what decentralised storage systems could best be used.

01 Juin Research overview – Advanced Manufacturing in Switzerland

Swiss Academy of Engineering Sciences (SATW)
June 2016
Authors: Pavel Hora, Christoph Klahn, Claudia Schärer Main themes: advanced manufacturing, additive Manufacturing, industry 4.0 Nature of publication: research overview English abstract (150 to 200 words): SATW is convinced that industrial production methods will see fundamental changes over the coming years. Mastering new production technologies (advanced manufacturing) such as additive manufacturing and industry 4.0 will be vital to keep Swiss production at a competitive level. New additive manufacturing processes such as 3D printing offer revolutionary opportunities and have the potential to replace traditional production methods. Industry 4.0 has seen the definition of a new concept for production control and product design, with the potential for major upheaval. Both topics are being discussed at conferences, and a number of Swiss research activities are already focusing on the two areas. SATW aims to help improve coordination between these activities in order to identify and improve weaknesses. To this end, SATW has created the “Advanced Manufacturing in Switzerland” research overview.
