Value Stream Mapping and Process Mining: A Lean Method Supported by Data Analytics

The analysis and further the reorganization of an order-production is a typical scope of application of a value stream mapping. Value stream mapping is a lean-management method to map the current state of a series of processes that are necessary to manufacture a product or provide a service. The ever-increasing digitalization emphasizes the importance of the information flow. Besides the material flow, the information flow is the second focus of value stream mapping. It is needed to get valuable insights into the production process by applying state-of-the-art data analytics methods. Process Mining is a possible method to analyse (business) process and process sequences based on event logs. This paper illustrates a method of combining conventional value stream mapping and Process Mining. While value stream mapping shows the material and information flow as the people think it is, Process Mining shows how they are, based on the data fingerprint. The comparison of the two outcomes allows conclusions for the following value stream design with a special focus on the use of data for Industry 4.0 applications. The application of both methods to an order-production enables to present results and compare both as well as present advantages and disadvantages

Key for the identification of the nymphs of the leafhopper subfamily Idiocerinae in Germany: (Hemiptera: Cicadomorpha, Cicadellidae, Idiocerinae)

For the first time, a key for the identification of the nymphs of the leafhopper-subfamily Idiocerinae is presented for the German fauna. Dichotomous keys lead to the 9 genera and most of the 25 species. The identification is supported by more than 60 drawings, thereof habitus drawings of all species.Erstmalig werden Bestimmungsschlüssel für die Larven der in Deutschland vorkommenden Arten der Zikaden-Unterfamilie Idiocerinae vorgelegt. Anhand detaillierter dichotomer Schlüssel sind damit sämtliche 9 Gattungen und die meisten der 25 Arten bestimmbar

Zur Zikadenfauna des Großen Arber im Bayerischen Wald: (Hemiptera: Auchenorrhyncha)

Contribution to the Auchenorrhyncha fauna of the Großer Arber, Bavarian Forest (Hemiptera: Auchenorrhyncha). – The fauna of plant- and leafhoppers of the Bavarian Forest is not well studied. On 30.06.2007 an excursion to the Großer Arber, which is the highest mountain of the range, was organized. In total, 27 species were collected. Together with results from an ongoing project on the altitudinal distribution of plant- and leafhoppers of the Bavarian Forest 50 species are now known to occur at higher elevations (above 1000 m) at the Großer Arber. Additionally, on 01.07.2007 a wet grassland site in the Zellertal near Arnbruck (520 m) was visited and 55 species have been recorded there.Contribution to the Auchenorrhyncha fauna of the Großer Arber, Bavarian Forest (Hemiptera: Auchenorrhyncha). – The fauna of plant- and leafhoppers of the Bavarian Forest is not well studied.
