    Plan authoring applications for emergency management
    (INFORMATIK 2011 – Informatik schafft Communities, 2011) Wollert, Alexander; Mannabeth, Ganga Vazhayil
    In this paper we present a semi-formal tool using the concept of process modelling for emergency management developed within our project InfoStrom. This is meant to be an aid for rescue forces, energy providers and public authorities, whose measures and terminologies generally differentiate. Also, they do not have up-to-date documents and manuals available that could be adapted to new types of emergency (natural disaster, technical casualties as well as terrorist attacks) or be analysed for efficiency. Our approach intends to provide the ground for formal modelling as enabler for analysis, comparison and process customisation to synchronise plans of different domains and to make them transparent for any involved organisation.

    Smart checklists for crises management planning
    (INFORMATIK 2013 – Informatik angepasst an Mensch, Organisation und Umwelt, 2013) Peinel, Gertraud; Rose, Thomas; Wollert, Alexander
    Planning in crises management is essential in order to guide operation staff through noise and chaos and also to counter stress, panic and overburdening of emergency services. This planning results in so called standard operating procedures (SOP), sketched out by legislations and handbooks, and adapted to local directives and conditions. SOPs are learned, trained and also translated to checklists, while hand-outs are placed in emergency vehicles and control centres for permanent availability. But so far, scant IT support is available to support the process of emergency planning. Emergency services have to rely on Office tools for creating and managing these plans, resulting in MS Word documents for a written description and Excel or Word tables for checklists. In this paper we present our concept of smart checklists and its first implementation, which enables emergency service organisations to design and exchange plans in terms of IT-supported checklists. A checklist resembles a lightweight process representation giving users the freedom to sketch their processes while maintaining sufficient formalization.

    The Dark Side of Photovoltaic – 3D Simulation of Glare Assessing Risk and Discomfort
    (Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Wollert, Alexander; Rose, Thomas
    Photovoltaic (PV) systems form an important force in the implementation of renewable energies, but as we all know, the force has always its dark side. Besides efficiency considerations and discussions about architectures of power distribution networks, environmental impacts caused by optical reflections are a serious concern. PV systems generate optical reflections resulting in glare. On the one hand, glare is a serious security concern, e.g. for traffic. On the other hand, glare is a constant source of discomfort in vicinities of PV systems. Location-oriented assessments are required to limit potential reflections and to avoid risks for public infrastructure and discomfort of residents. Hence, calculation of glare is decisive for the success of renewable energies with respect to solar energy. Several courts ruled on necessary adjustments of PV systems and even their de-installation because of glare effects. Our approach is to provide project planners with a 3D-based simulation software to calculate and visualise reflections towards the environment of PV systems. Hence, project planners receive flexible assistance for adjusting the parameters of solar panels before installation of a PV system.
