Abstract. This article discusses the process of identifying the problem areas of the product cycle by the value stream. Mapping value stream mapping allowed the development of a number of management solutions to increase productivity, optimize the process and improve the competitiveness of products. For the study a product manufactured by one of the industrial enterprises of the city of Samara was selected. The production process as repeatedly optimized by services of the plant, but its cycle is still and unstable. To solve these problems the pull scheme of production was proposed. The proposed method for the improvement of the production process on the basis of value stream mapping allows optimizing the production process, reducing the production cycle, improving the quality and efficiency of production. The final results were expressed in value terms. The final result showed that the use of this method allows reducing the duration of the production cycle for 42.28%, the cost of products -by 57.71%.
This paper describes the application of a ratio-delay to a study of operations of mechanical Job-Shop production in Samara factory. To analyze the operations efficiency it may be necessary to obtain organizational and technical data in each job stages. In fact, ratio-delay is an effective tool to determine direct labor productivity for shop floor activities. In the context of manufacturing operations, ratio-delay can determine productivity levels as a baseline that provides focus for new “industrial engineered” improvement measures of complex re-engineering project or lean management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
