The changes in the operating conditions of the main control room of nuclear power plants due to new digitalized human-system interfaces (HSIs) pose challenges to traditional human reliability analysis (HRA) methods. This paper reviews current knowledge about the effect of digital HSI on human behaviour and reliability, relevant performance shaping factor (PSF) taxonomies as well as research on the effect of PSFs on human error probability estimates in advanced control rooms (ACRs). It cannot be generally concluded that either analogue or digitalized control rooms would be always better than the other. ACRs have the potential to offer error reducing and supportive features to the user, but may also introduce increased complexity and interface management tasks as well as potentially error-prone team working practices. Some effects seem universal, but most depend on the specific design. The main PSF categories presented in HRA methods and international guidelines seem still relevant in ACRs. Quantitative empirical studies show that especially training and experience, availability and quality of procedures as well as task type or complexity are important factors. However, digitalization changes the way in which the PSFs should be defined and measured, and the effects of PSFs on the error estimates may be different.

The objective of this study is to build up a common approach for the assessment of logistics innovations. Innovations are referred to here as best practices and are considered as existing approaches or solutions providing an answer to a relevant problem or challenge in freight transport. The impact evaluation of logistics innovations takes into account strategic targets, topics covered, transferability and novelty of the best practices. A freight specific multicriteria analysis approach was designed for the evaluation process.

The risk of fatal road accidents in winter between studded and unstudded tires does not differ significantly. However, the accident risk has recently been substantially higher on bald ice for unstudded than for studded tires. The magnitude of this risk difference is difficult to determine without specific information on exposure by road surface.
