The main task of machine-building enterprises is the timely provision of the market with competitive products. The solution to this problem is possible on the basis of continuous improvement of production processes for the manufacture of engineering products based on the use of quality management methods. The manufacturing of engineering products is a complex and time-consuming process consisting of a large number of stages of production of individual units and parts as well as the assembly and testing of all elements. Consequently, a simultaneous improvement of all production stages of engineering goods in the existing production is impossible since this will cause disorganization of the production process as a whole. Therefore, in the conditions of operating production, the improvement of production processes should be carried out step by step starting from the stages that require a priority improvement and using a sound combination of quality management methods that take into account the specific features of the particular enterprise. The variety of quality management methods and quality control tools complicates the task of selecting them for each specific production process. For its solution, it is proposed to use the criterion of Taguchi signal/noise. As a criterion for the effectiveness of implementing the stages of improving the production process using quality management methods, it is suggested to use a dynamically integrated indicator of the quality of the production process. The proposed mechanism for managing the continuous improvement of production processes is considered by the example of manufacturing processes for the manufacture of gas turbine engine pipelines.
The article discusses the sequence and content of the stages of the introduction of lean manufacturing tools and visual management in order to adapt them to domestic enterprises. A typical sequence of stages of implementation of the visual management system at the enterprise is given. The main disadvantages of its implementation at Russian enterprises are listed. A modified sequence of stages of the introduction of visual management tools is proposed, taking into account the specifics of domestic enterprises with a detailed description of each stage. A dynamic model of personnel training is proposed for use as part of the implementation of the stage of creating conditions for the introduction of visual management tools. The approximate composition of competencies and the scale of their assessment for conducting an expert assessment of the level of development of competencies of each employee has been determined. The efficiency indicators of the introduction of lean production tools, in particular, visual management tools, which best demonstrate for employees the economic feasibility of the proposed solutions for the introduction of lean production tools, are substantiated. It is shown that the implementation of the proposed sequence of stages will allow: to prepare employees of enterprises in a timely manner for the expected changes; to endow employees with the appropriate competencies to put forward effective proposals for the further development and implementation of lean production tools; to increase employees' awareness of the need, relevance and effectiveness of the proposed changes based on understandable performance indicators determined for each specific division of the enterprise.
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.
