Methodic for Analyses and Ranking of Quality Risks at Production Assembly Line

Abstract

Methodic of evaluation of assembly line in order to evaluate level of protection of working places from quality risks is described in the article. Topic is actual because in normative documents there is only regulation of requirements for the product, but there is no risk evaluation methodic for production line. Novelty of the topic is that according to developed methodic there is possibility to evaluate general risk level of the assembly process and conduct analyses for single risks, which has an influence on security level of the line from making a failure. Authors of this article defined following tasks: to make evaluation of each working place of the line; to develop list of designations for possible risks of assembly; to develop mathematic model for calculation of general risk level. During implementation process was evaluated process of oscillating system assembly for washing machines. Interpretation of results of risk evaluation executed. Algorithm for risks clustering is described with determination of most critical assembly operations, which are leading to high quality risks and financial losses, needed for risk elimination. Usage of described methodic gives opportunity to improve general risk level to secure the line from quality failures, as a result to improve quality of the final product.
