Analysis of User Groups for Assistance Systems in Production 4.0 The fourth industrial revolution aims to digitize the production chain. The goal is to optimize production processes while minimizing error rates and contemporaneously increasing the productivity. Not only the production lines are considered, but also the employee himself, for whom the working environment should be designed to be more comfortable, ergonomic and adapted to the individual needs. To get closer to this goal, assistance systems can be used, which accompany the worker through appropriate support during the daily work routine. The following paper discusses various assistance systems both identified in scientific literature and on the market, as well as categorizes diverse user groups in the present production 4.0. As a result, the paper provides a proposal for the matching of assistance systems with the identified user groups.

A Decision Support System for rapid rampup of industry 4.0 enabled production systems Abstract   Production rampup is a key phase during the introduction or changeover of a production system. Process calibration and tuning are inevitably required to make such a system fully operational and let it reach its maximum production yield. A complex decisionmaking process takes place in order to optimally tune the system and requires a long time for testing and experimenting that will determine the system behaviour. This work considers the sequential nature of rampup and proposes a CyberPhysical Systems approach based on data capturing, learning mechanisms and knowledge extraction, leading to an Industry 4.0 compliant Decision Support System (DSS) for human operators. The proposed system is implemented as an online DSS and also supports offline learning using previously gathered knowledge. A number of experiments have been carried out on a micro scale assembly station, validating the expected benefits of the proposed DSS. Results show a reduction of over 40% in the number of rampup steps required when using the DSS.
