ABSTRACT

Generally speaking, none of us want to keep our clothes with dirt. One of things people do on a daily basis is to wash their clothes and dry them. Considering that the amount of fresh water is limited and the abuse of detergents may cause environmental pollution, this article simulates the general process of washing clothes using a washing machine by constructing a corresponding mathematical model. This article considers the different washing times and the changing trend of the proportion of stains in the clothes-water-detergent-dirt system under different initial amounts of stains, different detergent usage, and different washing times, based on the assumption that there are certain rules for the solubility of detergents. At the same time, it collects some information about the solubility of stains and detergents, and proposes a solution that minimizes the total cost through a 0-1 integer programming model. This research will probably benefit laundry while saving both water and energy.
