Michael-Burkhard Piorkowsky Tag der mündlichen Prüfung: 01.07.2011 Erscheinungsjahr: 2011 Abstract Many tests and consumer surveys have shown that manual dishwashing at home is done in very different ways, taking also different amounts of resources. Because almost every household, whether owning an automatic dishwasher or not still keeps on washing up a few items by hand, it seems necessary to investigate manual dishwashing regarding optimisation. Therefore, a project was run at the University of Bonn to find out an optimal way to clean the dishes by hand. Optimisation in this case means to reach a reasonably good cleaning performance with the minimum amount of resources, as water and energy for example.
