Production Concept

Subject. The article discusses the use of the lean production concept at the production enterprise. Objectives. We evaluate the existing lean production toolkit, determine opportunities for their implementation and possible difficulties. Methods. Methodologically, the study is based on the comparative analysis of methods that constitute the lean production system. Results. We review one of the economic security aspects for Russia, such as an increased production competitiveness due to the ubiquitous implementation and use of lean production instruments. We conducted an historical analysis of the origination and development of the production process approach. Some lean production tools and aspects were proved to have been designed and actively used in the USSR manufacturing sector since the 1960s. The lean production concept was found to become very appropriate for enterprises. We analyzed the continuing production planning system by A.S. Rodov, which were in use ans proved its high cost efficiency at the USSR industrial enterprises. We also delved into the profit generating production process that was put in place in Toyota. The article provides the comparative description of modern lean production methods and concludes on their future use. Conclusions. Having compared the Soviet lean production model and the classical Japanese one, we concluded on the use of such production process methods that really went beyond their time. In the mean time, the Soviet model was simpler to use and implement. Based on the overview of modern lean production tools that evolved from the Soviet and Japanese lean production theories, we believe that the lean production principles and methods will have a positive impact on the efficiency and competitiveness of the national manufacturing sector.

The analysis of the current state in the field of regulation and organization of employment of the population of the country is carried out. The current problems of the employment centers ' activities are identified and a list of measures aimed at solving these problems is formed, based on the introduction of the concept of Lean production. An adapted practice-oriented approach is proposed to introduce the principles, methods and tools of Lean production as the main set of measures to improve the processes of providing public services to the population and eliminate the time, financial and labor costs that arise during the operation of employment centers. The proposed approach to implementing the concept of Lean production is tested on the example of the State Enterprise of the YAO TSN G. Yaroslavl.

AbstractThe paper presents the technology and organization of the artistic cast production. On the basis of the actual cast production system, the manufacturing process was shown, in particular sand–piece moulding, which is a very important process and a time-consuming part of the entire manufacture of the casts. The current state of the production process as well as the organization of the work and production technology were analysed with the use of methods and techniques of production improvement, the Lean Manufacturing concept and computer systems. The results of the analysis and studies were shown with use of schemes and graphs of the layout of the production resources, a flow chart of the production process, value stream mapping, and a costs table for the production and modernization of the moulding stage. The work has shown that there are possibilities to improve the artistic cast production system. This improvement leads to increased productivity, lower production costs of artistic casts and increased competitiveness of the foundry.

CV.X merupakan salah satu perusahaan pengolahan sarden yang terletak di Banyuwangi. Pada proses produksi di perusahaan masih ditemukan beberapa pemborosan (waste). Untuk mengurangi pemborosan yang terjadi digunakan pendekatan lean manufacturing dengan metode Value Stream Mapping (VSM) untuk pemetaan aliran produksi dan aliran informasi terhadap proses produksi dari awal bahan baku hingga produk jadi dan dikirim ke konsumen, serta analisis dengan metode Failure Mode and Effects Analysis (FMEA) untuk mengetahui penyebab kegagalan proses yang paling prioritas dan perlu dilakukan perbaikan dengan segera. Identifikasi pemborosan diawali dengan penggambaran current state map, lalu dilakukan analisis pemborosan ke dalam kategori 7 pemborosan [1]. Pada analsis tersebut ditemukan 3 jenis pemborosan yaitu waiting time, unnecessary inventory dan defect (kembung). Setelah itu dilakukan analisis akar penyebab timbulnya pemborosan menggunakan fishbone diagram, dan analis FMEA untuk mengetahui nilai RPN tertinggi yang selanjutnya akan menjadi prioritas pemberian usulan perbaikan yang tepat dan sesuai dengan masalah dan kondisi proses produksi sarden 125g di CV.X. Rekomendasi perbaikan yang diberikan terhadap pemborosan dengan nilai RPN tertinggi antara lain Menambahkan mesin pencuci produk untuk mengurangi penumpukan produk dan waktu tunggu yang ada sehingga pemborosan waiting time dan unnecessary inventory dapat berkurang, mengganti sarung tangan kain dengan lateks, serta menjaga kebersihan nampan ikan. CV.X is a sardine processing company located in Banyuwangi. In the company production process there are some wastes. To reduce the waste that occurs, lean manufacturing approach using Value Stream Mapping (VSM) method is used to map the production flow and information flow to the production process from the beginning of the raw material to the finished product and sent to consumers, as well as analysis using the Failure Mode and Effects Analysis (FMEA) method. ) to find out what causes the most priority process failures and needs immediate improvement. Waste identification is preceded by a depiction of the current state map, then waste analysis is conducted into category 7 waste. In this analysis, there are 3 types of waste, which are waiting time, unnecessary inventory and defects. After that an analysis of the root causes of waste occurs using fishbone diagrams, and FMEA analysts to find out the highest RPN value which will then be prioritized for giving recommendations for an appropriate improvement and in accordance with the problems and conditions of the 125g sardine production process in CV.X. Improvement recommendations given for waste with the highest RPN value include adding a product washer to reduce product buildup and waiting times so that waiting time and unnecessary inventory waste can be reduced, replacing cloth gloves with latex, and keeping the fish tray clean.

The Cost

This work describes a strategy to reduce the cost associated with poor quality, by reducing the parts per million defects by Defining, Measuring, Analyzing, Implementing and Controlling (DMAIC) the production process. The method uses a combination of principles of Six Sigma applications, Lean Manufacturing and Shanin Strategy. The process has been used in analyzing the manufacturing lines of a brake lever at a Connecticut automotive components manufacturing company for reducing the cost associated with the production of nonconforming parts. The analysis was carried out with the help of the data collected on nonconformance parts and the application of phase change rules from DMAIC (+). Data analysis was carried out on statistical process control softwares, MINITAB and SPC XL 2000. Although, the problem of tight bushing existed on only one line of the brake lever assembly, this problem solving approach has solved the tight bushing problems on all assembly and alternates lines in a time- and cost-effective way.

The research is devoted to the substantiation of the necessity of innovative transformations of the value chain of pharmaceutical enterprises. The current state of the international pharmaceutical market and its development scenarios developed by the WTO were analyzed, taking into account the changes caused by the COVID-19 coronavirus pandemic. The typology of value chains is considered and their element-by-element characteristics are given. A new, modern model of interaction in the chain of value creation of products is proposed. The substantiation of efficiency of creation of such chains is given. Based on the correlation analysis, the presence of a linear relationship between the indicators of Pharmaceutical R&D Spend and Revenue was established. To maximize the effect of R&D costs, pharmaceutical companies are recommended to carry out innovative transformations of the value chain, involving external manufacturers of high-tech devices, applications, etc.
