Sommario/riassunto |
|
Mathematical modelling is a powerful tool for solving optimisation problems in chemical engineering. In this work several models are proposed aimed at helping to make decisions about different aspects of the processes lifecycle, from the synthesis and design steps up to the operation and scheduling. Using an example of the Sugar Cane industry, several models are formulated and solved in order to assess the trade-offs involved in optimisation decisions. Thus, the power and versatility of mathematical modelling in the area of chemical processes optimisation is analysed and evaluated. |

Sommario/riassunto |
|
Unterrichtsnachbesprechungen sind zentrale Formate im Vorbereitungsdienst, objektive Einblicke in die praktische Umsetzung sind allerdings marginal. In dieser Studie steht die systematische Auseinandersetzung mit der praktischen Umsetzung und Ausgestaltung dieser multilateralen Gespräche im Zentrum. Mittels eines triangulativen Designs werden zunächst die Themen der Besprechungen aufgedeckt und Hinweise auf praxisrelevante Merkmale zur Einschätzung von Unterricht geliefert. Die deskriptive Betrachtung richtet den Blick auf die räumlichen und zeitlichen Rahmenbedingungen, den Ablauf der Gespräche und die Zusammensetzung der Gesprächskreise. Die vergleichende Betrachtung der Redebeteiligungen der Teilnehmenden macht auf besonders dominante Personen und Akteursgruppen aufmerksam. In der rekonstruktiven Analyse werden spezifische rollengebundene |

Interaktions- und Kommunikationsmuster sichtbar. Je nach Rolle werden den Teilnehmenden durch den Modus Operandi dieser Formate unterschiedliche Möglichkeitsräume zur inhaltlichen Beteiligung und interaktiven Mitgestaltung eröffnet, diese aber auch gleichermaßen begrenzt. |
