“…Recent progress in machine learning and artificial intelligence (AI) might enable further refinement of cell culture automation towards smart technologies ( Göppert et al, 2018 ; Jung et al, 2019 ). Such systems may exploit in-process-data such as automatically assessed confluency values and machine learning-based image analysis ( Schenk et al, 2015 ; Rippel et al, Unpublished) for adaptive cell processing involving autonomous decision making and prioritization of process scheduling ( Supplementary Figure 5 ; Jung et al, 2018 ).…”

“…Secondly, through the individual and ad-hoc decisions of choosing a new sink, there is no overall defined cycle time, which is similar to each process module [5]. Therefore, the sequence of different orders might change inside the system [20]. Furthermore, there are multiple product and order flows in one matrix system [20].…”

Today's productions are driven by increasing variants, uncertainty of variants' distribution as well as volume and shorter innovation cycles. A matrix manufacturing system aims to tackle these challenges. This new system concept consists of independent and flexibly linked process modules, which have no uniform cycle time and no fixed product order sequence in the system. However, new challenges arise from this system setup. The changes in the structure have an impact on logistics. In research, there are only a few investigations regarding the consequences to logistics, especially to material supply. Common and new innovative supply strategies are used without knowing their suitability to the new system. The applicability of kanban, single product supply or kitting basket supply differs to the usage in a line assembly. A systematic derivation of suitability in the new context is missing. The paper fills the gap of research in the outlined field. Firstly, changes and characteristics through the new structure which occur as challenges to the material supply are investigated. These are e.g. the flexibility of order and process sequences. In a second step, the material supply strategies are evaluated according to strategic requirements. As a result, each material supply strategy's suitability is evaluated for usage in matrix manufacturing systems. The paper concludes with a derivation of guidelines for the planning and selection of a material supply strategy.

“…Eine besonders in der Automobilindustrie, aber nicht beschränkt auf diese, gewonnene Erkenntnis ist, dass klassische Linienfertigungen an ihre Grenzen zu stoßen drohen, wodurch eine Abkehr von diesem Fertigungsprinzip hin zu flexibleren Systemen zu untersuchen ist. Erste Pilotprojekte sind hierbei bereits gestartet [9]. In der Praxis sind verschiedene Bezeichnungen und Spielarten, wie beispielsweise "modulare Montage" [2], "Flexi-Line" [14] oder "Full-Flex-Werk" [4] zu finden.…”

Der Wunsch nach mehr Flexibilität in Fertigungssystemen, insbesondere, wenn verschiedene Produkte bzw. viele Produktvarianten in einem Produktionssystem gefertigt werden, führt, besonders in der Automobilindustrie, zur Abkehr vom Fertigungsprinzip der klassischen Linienfertigungen hin zu eher flexiblen und werkstattorientierten Produktionssystemen. Eine der Herausforderungen in diesen so genannten modularen Montage-bzw. Produktionssystemen ist das Systemdesign, insbesondere die Zuordnung der Tätigkeiten auf die einzelnen Fertigungsinseln. Einen Ansatz, diese Zuordnung zu verbessern, bietet die simulationsbasierte Optimierung. In diesem Beitrag wird ein Konzept zur simulationsbasierten Optimierung der Tätigkeitszuordnung zu einzelnen Fertigungsinseln in modularen Montagesysteme vorgestellt und anhand einer Fallstudie demonstriert. Zum Einsatz kommen hierbei genetische Algorithmen, speziell der NSGA-II-Algorithmus, welcher auch mehrkriterielle Optimierung ermöglicht.
