Purpose. Analysis of the features of the transition to the concept of lean production of enterprises of the mining and metallurgical complex (MMC) of Ukraine, located on the territory of the Dnipropetrovsk region. Prospects for the implementation of these approaches to 2020. Methodology. While writing the article, the following methods were used: questioning and interviews at the stage of collecting primary information, as well as the method of comparative analysis in justifying recommendations regarding the prospects for implementing the concept of lean production for the period up to 2020. Findings. The article analyzes the transition to the principles of the concept of lean production on the example of two enterprises of the MMC of Ukraine, geographically located within the Dnipropetrovsk region. The prospects for further implementation of the tools of the Lean Production concept for the period up to 2020 are considered. Originality. The importance of the practical application of methods and tools of the theory of the concept of lean manufacturing, in particular of the 5 C system and of the Submission of Proposals was confirmed. The necessity of applying various methods of auditing production activities was proved. This will optimize costs within the organization and affect the level of competitiveness of its products. Practical value. Understanding the fact that the company's profit is only an external manifestation of the correct management decision to minimize losses within the company will allow enterprises of the mining and metallurgical industry of Ukraine as a whole to progress.

Production Areas

Striving to improve productivity, industries have used different management approaches, being lean manufacturing the most used over recent years. Lean manufacturing is based on value creation for the customer and elimination of waste that occurs during the production process, while improving working conditions. The incorporation of ergonomic aspects in the workstation design also contributes for the referred objectives, since it will reduce awkward postures or excessive effort during work, leading to better working conditions and increased productivity. The present study highlights, through a case study in four production areas of a metallurgical industry, the benefits of using an integrated operations management approach to improve productivity and ergonomic aspects. Several ergonomic methods, such as Rapid Upper Limb Assessment (RULA), Strain Index (SI), and Rapid Entire Body Assessment (REBA), were chosen to evaluate the ergonomic situation and lean manufacturing tools such as Value Stream Mapping (VSM) and 7 wastes were also used to analyze the systems and increase the productivity by eliminating several wastes. The results of this study show that it is possible, and desirable, to consider both aspects, ergonomic conditions and productivity, during continuous improvement’ implementations. In fact, the improvements reached through the advances in ergonomic conditions can contribute very positively for productivity increasing.
