Model of Evaluation of Technical Level for Household Appliances

Abstract

The article presents a model, which includes the list of consumer qualities for evaluation of technical level of washing machines using developed scoring system for each characteristics and parameters weight coefficients. The evaluation of washing machines according to developed model is performed and recommendations for improving of quality level of washing machines in technical field are given. Evaluation of safety, functionality and reliability of appliance is a base for quality evaluation of household appliances. This topic is actual because the normative documents regulate the requirements for the product, but there is no methods, needed for evaluation of product from technical point of view. Novelty of the topic is that developed methodic allow to evaluate technical level of appliance, to define advantages and disadvantages of produced products based on weighting factors of parameters, calculated according to consumer properties and technical characteristics. The authors of this article defined following tasks: to develop registers of consumer properties with detailed nomenclature of indicators for evaluation of technical level according to normative documentation, to calculate weighting factors of parameters for each level of consumer properties, to define measurement method of each parameter, to develop evaluation model for technical properties and scale for evaluation. The developed method was used in production of household appliances (washing machines). During evaluation process, a number of models were evaluated and the products with low technical level were identified. The developed method gives an opportunity for production firms to analyze quality of products from point of view of safety, functionality and reliability and to define parameters, which are needed to be improved.
