Requirements engineering for stakeholders of factory conversion: LoD visualization of a research factory via AR application

Restructuring in factories is becoming increasingly important to maintain the competitiveness of a factory. In the planning and construction of a factory building, many different project participants turn a construction project into a highly complex task. In the research factory Arena2036 of the University of Stuttgart, in addition to the original research areas of the mobility of the future the building itself is also regarded as an object of research. A method is proposed that uses elements of requirements engineering and enables the user to make a structured decision about the type of a digital building model and its LoD. Requirement templates enable a quick identification of requirements of all stakeholders. The method is suggested to find out which information is important for the stakeholders and what type of digital building model, in which LoD is required for the conversion. Based on this an Augmented Reality application is developed to support the exchange of technical planners during a factory restructuring. The exchange between technical planners is to be streamlined by the application and planning phases shortened. The experiences of using the application are presented and it is proposed as a first step towards a didactic concept in the Arena2036.
