【 摘 要 】

This article deals with the possibilities of risk evaluation of product quality nonconformity found at production. In first parts of article main steps needed for risk analyses are defined, including created by the author's mathematic models for risk evaluation and scoring system for characteristics, weighted based on expert consultation. In the following part developed methodic is approbated at production of household appliances on example of washing machines production. Risk of increase of technical call rate and warranty costs are evaluated. General risk level based on probability of risk occurrence, severity of risk consequences is also calculated. In the last part, using the knowledge from the previous parts document for evaluation of risks of quality nonconformity found during production process is created.
