The article examines the sequence of actions to eliminate losses in the production process with the help of lean production tools at the Russian engineering plant. At the same time, the tasks are solved: the stages of the process of identification, analysis and problem solving are analyzed, the algorithm of elimination of losses in the production process is shown, an algorithm is proposed to build a map of the flow of the value creation of the current state of the production process of the manufacture of the part, the tools of lean production to eliminate the main losses are presented.  With the systematic and concerted development of these tools, with the active advice and support of the management of the engineering company, the management of the production process on the basis of the concept of lean production allows to reduce losses, help to grow and develop the plant.

Introduction. Adverse effects of environmental factors can cause dysfunction of organs and systems, hormonal dysfunction, genetic disorders, which can adversely affect the health of future generations. The aim is to study occupational risk factors and assess their impact on the health of male workers of machine-building enterprises, to develop preventive measures. Material and methods. The working conditions of 318 male workers of the main professions of the machine-building enterprise (miller, locksmith, electric and gas welder, turner, caster, etc.), having occupational contact with harmful occupational factors, were studied in comparison with 148 employees of the control group. Epidemiological, socio-hygienic, statistical and risk calculation methods were used. Results. 68.2% of respondents were found to have occupational contact with cutting fluid, 24.3% contact with chemicals, 14.4% - with heavy metals, 66.2% of respondents work in conditions of noise exposure, 40.1% - local vibration, 22.3% - in conditions of hypothermia, 14.4% - in conditions of overheating. Excess of maximum permissible concentrations of benzo(a)pyrene, aerosols of mineral oils, epichlorohydrin was detected in the air of the working zone. At workplaces, there were excess levels of noise, general vibration, thermal radiation. The impact of harmful occupational factors in the workplace was established to create a high risk to the health of workers. Conclusion. Working conditions of workers of the machine-building enterprise are mainly estimated as harmful. Critical organs and systems for the development of occupational pathology were identified, the high carcinogenic risk from exposure to benzo(a)pyrene was revealed. Employees of the machine-building enterprise were shown to have a high risk of oncology, respiratory diseases, central nervous system diseases, pathology in offspring. As a result, risk groups were formed and targeted preventive measures were proposed, including monitoring of the health status of high-risk groups, occupational selection, and medical examinations.

Business in modern business conditions requires a continuous process of improvement and investment in all activities in the company. In order to survive on the market, resist the challenges of competition, but also the demands of customers, companies are constantly innovating the production process in an effort to improve all the company's activities. One of the production systems that proved to be suitable for continuous improvement and improvement of the production process is Lean production system. It represents the way companies react to the challenges of the present and the future. The Lean production system offers a variety of instruments, and for their implementation and application, managers are at all levels of responsibility and responsibility. Bearing this in mind, it can be said that the Lean production system is part of the management accounting. In addition, it represents a complete philosophy of thinking and action, which results in significant results by adequate application. The condition and the assumption that this management philosophy will lead to proper effectiveness and efficiency and enable them to continually improve in the function of maximizing profits is the authorization of employees to engage in the process of continuous improvement and decision-making. Lean is based on certain principles and philosophies, including customer value, value flow mapping, continuous flow, system requirements, and continuous improvements. Lean focuses on the added value. Lean's principle is a continuous search for perfection, perfection in production and business cooperation, with complete elimination of losses. Companies that implement the Lean Concept are constantly looking for ways to continually improve their efficiency, reduce costs and improve the quality of their products.

In the absence of uniform and unified requirements for the assessment of industrial risks at an enterprise, the system approach remains the only tool for a comprehensive assessment of the workplace safety. Implementation of Occupational Safety and Health (OSH) system involves identifying, analyzing and reducing risks at the workplace. The purpose of the article is to calculate the minimum expenses for occupational safety measures and minimize production risks identified through the developed procedure for analyzing the hazards of the machine-building enterprise. The research methodology is based on the integrated use of qualitative and quantitative approaches to risk assessment, namely, structured assessment and integral assessment using the “rucksack problem” optimization model. The study identifies the risks that are most common and the most serious ones. The procedure of risk reduction is proposed, which is to determine the minimum costs for achieving each of the integral assessments for the machine-building enterprise. The practical value of work consists in the ability to directly apply the developed methodology for risk assessment at the enterprises of the machine-building industry, and to easily adapt the risk assessment procedure to other conditions.
