Focusing on the internal materials supply system (MSS), this thesis emphasizes the importance of a concurrent engineering (CE) approach in product development. It highlights the need to integrate logistics considerations early in the design process to enhance both quality and time-to-market. By involving relevant stakeholders in defining MSS requirements, the thesis proposes a structured framework to facilitate this integration. The findings are supported by literature reviews and a case study conducted in the automotive manufacturing sector.

Der Ansatz des Concurrent Engineering (CE) wird genutzt, um die Produktentwicklung durch gleichzeitige Berücksichtigung verschiedener Aspekte zu optimieren, insbesondere im Hinblick auf Qualität und Markteinführungszeit. Die Arbeit untersucht das interne Materialversorgungssystem (MSS) und hebt hervor, dass logistische Überlegungen oft zu spät in den Entwicklungsprozess integriert werden. Durch eine frühzeitige Einbeziehung der MSS-Anforderungen soll eine Struktur entwickelt werden, die alle relevanten Interessengruppen einbezieht. Die Ergebnisse basieren auf Literaturrecherchen und einer Fallstudie in der Automobilindustrie.

With the advent of the household refrigeration system in 1910, the modification to the core technology has been very less. The system has a compression machine designed for continuous automatic operation and for the conservation of the charges of refrigerant and oil and is usually motor driven and air-cooled. The compressor used is a power consuming component. It consumes around 90% of the total rated consumption in a refrigerator. This project emphasizes the working of a refrigeration system which does not have a compressor. The refrigerator has no rotary power consuming component, so the system has greater life longevity. The working is based on Peltier cooling comprising of a Peltier module. This is an energy efficient system consuming minimum power. Further, it also acts as a heater unit providing a localized heating. It is an air-cooled system having no flow of refrigerant. This further reduces the environmental concerns surrounding the use of a refrigerant, which has been part of great debate nowadays.
