Ihr Kernproblem ist, dass Werkzeuge nicht aus bereits eingetretenen Fehlern automatisiert dazulernen. Zur L{\"o}sung wurde in dieser Arbeit das maschinelle Lernen (ML) evaluiert, indem ein wissenschaftlich fundierter und praktisch erprobter Ansatz zur un{\"u}berwachten Lerntechnik angewandt und das Ergebnis analysiert wurde. Es wurde festgestellt, dass zur Anwendung auf verschiedene Programmiersprachen nur ein sprachspezifisches API Mining-Tool notwendig ist. Ein derartiges Tool durchsucht in parallelisierter Form Codezeilen und normalisiert sie f{\"u}r maschinelle Lernprozesse. Dieses System wurde f{\"u}r die Programmiersprache C\# implementiert, da viele Industrieprojekte in dieser Sprache entwickelt werden. Zur funktionalen Validierung wurde in einer Fallstudie gezeigt, dass Regeln mit einem positiven Effekt auf Software-Qualit{\"a}t gelernt wurden. Konkret wurde der Wartungsaufwand eines Code-Smells in einem Beispielprojekt durch das Auslagern einer gelernten Assoziation in eine gemeinsame Methode um den Faktor 30 reduziert. Die Laufzeit des Algorithmus wurde empirisch in acht open-source Repositorys evaluiert. Durch Parallelisierung kann eine durchschnittliche Laufzeitverbesserung von 45,16\% erwartet werden. Allerdings wurden bei der Anwendung auch Grenzen deutlich: Viele Assoziationen sind nutzlos, die Regelbewertung ist von einem subjektiven Faktor abh{\"a}ngig und die Wirtschaftlichkeit des Tools ist deshalb nicht transparent. Dennoch belegt diese Arbeit, dass ein ML-basiertes SCA-Tool als erg{\"a}nzende Qualit{\"a}tssicherungsmaßnahme im Software-Engineering m{\"o}glich ist.}, language = {de} } @article{Herrmann, author = {Herrmann, Frank}, title = {Der Einsatz von ITK zur Abfallreduktion im Lebensmitteleinzelhandel}, series = {Russian Journal of Applied Sciences}, journal = {Russian Journal of Applied Sciences}, pages = {100 -- 104}, abstract = {Die Abfallproblematik in Nahrungsketten ist ein weltweit wichtiges Thema, wor{\"u}ber in vielen Medien h{\"a}ufig berichtet wird.

However, social sustainability has received less attention, especially compared to the economic aspects. Next to technical and organizational measures, social improvements within supply chains can also be achieved through suitable production planning. Within production planning, production programs are determined, and the assignment of available resources (e.g., employees) is specified. Thus, the utilization and workload of employees are defined. This systematic literature review investigates to what extent such employee-related social aspects are reflected in production planning and discusses whether economic aspects dominate them. For this, a Scopus database search was carried out and 76 identified approaches were analyzed and categorized regarding the occurring employee-related social aspects and their implementation. Thus far, the approaches mainly consider single aspects on single planning levels. A consideration of a broad set of aspects along the entire production planning has rarely been studied. In particular, health and safety aspects are considered on the levels of assembly line balancing and job rotation. However, their impact is primarily determined by the specific settings of the decision-maker. To support decision-makers, only a few studies have investigated the effects based on real application scenarios. Further potential might be an extended modeling of social and economic interdependencies and a consideration of employee-related social aspects in medium- to long-term production planning.}, language = {en} } @book{Herrmann, author = {Herrmann, Frank}, title = {Lineare Optimierung unter Unsicherheit}, publisher = {Springer Fachmedien}, address = {Wiesbaden}, isbn = {978-3-658-34580-8}, doi = {10.1007/978-3-658-34581-5}, abstract = {Modellierungsalternativen werden mathematisch exakt formuliert; St{\"a}rken und Schw{\"a}chen der derzeit eingesetzten Modellierungstechniken werden demonstriert; Leicht nachrechenbare Fallstudien}, language = {de} } @article{DavendraHerrmannBialicDavendra, author = {Davendra, Donald and Herrmann, Frank and Bialic-Davendra, Magdalena}, title = {Chaotic Flower Pollination Algorithm for scheduling tardiness-constrained flow shop with simultaneously loaded stations}, series = {Neural computing \& applications}, journal = {Neural computing \& applications}, publisher = {Springer Nature}, doi = {10.1007/s00521-022-08044-0}, abstract = {This paper introduces a novel chaotic flower pollination algorithm (CFPA) to solve a tardiness-constrained flow-shop scheduling problem with simultaneously loaded stations.
