Optimization methodology of product technical characteristics in the production of household appliances

Abstract

The paper presents optimization methodology of product technical characteristics, which was approbated by optimization of conductivity of water on washing machine production factory. This process ensures effectiveness of rinsing process during washing cycle and reduction of chemical ingredients after rinsing. Main factors, which influence conductivity function, were defined. The factors are analysed to define dependence of investigated values from each other. Developed linear multiple regression model, quality of developed model are checked. Due to usage of the developed methodology at washing machine factory quantity of chemical ingredients after rinsing process was reduced; as a result, norms of GOST standard 60456-2011 were reached.
