Application of qualimetry methods for quality assessment of production processes at components suppliers enterprises

Abstract

Abstract It is practically impossible to efficiently manage the quality of the production process without determining the quantitative values for the indicators of its properties. Assessing the quality of the production process on a single, even decisive, indicator gives a one-sided, limited characteristic of the process, usually with a large number of properties. Therefore, for almost any process, especially for complex and multi-operational ones, it is necessary to carry out a comprehensive assessment on several parameters. In this regard, the indicator of the quality of the production process can be a complex, comprehensive indicator, depending on the single indicators of individual properties of the process. Such indicators include the indicator of continuity, the indicator of specialization, the indicator of plan fulfillment, the indicator of defect-free production, the indicator of progressivity, and the indicator of technical and economic efficiency. The purpose of the study is to develop a methodology to use qualimetry methods for assessing the quality of industrial processes at industrial enterprises. The objectives of the study: to determine the stages of qualimetric assessment of the quality of production processes; to develop the methods for calculating individual and integrated indicators of the quality of production processes; to practically implement the proposed stages of qualimetric assessment of the quality of production processes. Research methods: qualimetric assessment methods, including expert method (preference method), integral assessment method. Results. Indices that can act as single indicators of the quality of the production process are listed. The method to calculate the comprehensive indicator of the quality of the production process is shown on the example of the production process of manufacturing pipelines for gas turbine engines. Findings. The proposed methodology for qualimetric assessment of the quality of production processes can be used when improving processes, and a comprehensive indicator of the quality of a process can act as a criterion for the efficiency of ongoing improvement activities.
