Value stream mapping is used to analyze and improve the production flow in many industries, which includes the airplane and automobile industries worldwide. The shipbuilding industry has adopted lean manufacturing techniques. However, the amount of value stream mapping application in the shipbuidling industry is still relatively sparse due to the large variety of interim products and ship types. The aim of this paper is to analyze the interim products of a typical sized commercial shipyard with a product mix of chemical tankers and asphalt barges to demonstrate how a lean transformation can be performed using a shipyard value stream mapping methodology. The case study maps the typcial panel assembly lines of the shipyard and demonstrates the differences between the ship type interim products and using the lean manufacturing methodology developed by the authors to demonstrate how to define and adjust the production facilities using both lean and group technology techniques to create an improved production line which is demonstrated through a future improved value stream map. The main criteria for analyzing and comparing production improvement is through man-hours and duration time. The future value stream map has improvements of up to 50 percent, which demonstrates the importance of adopting a value stream mapping methodology for shipyards aiming to improve world competivity by decreasing production costs, while maintaining and/or improving quality of the ship buidling blocks.

Lately, value stream mapping (VSM) is integrated with tools and techniques that belong to other areas of knowledge such as risk management (RM). It is well known tool in showing the value, value stream and the flow which represents three of lean manufacturing (LM) principles. This integration, gives more benefit in covering two of VSM issues such as considering the variability and uncertainty of production processes. In this paper, a model named variable value stream mapping (V-VSM) that integrates the two was showed, explained and tested. The model helps to generate the VSM in a dynamic way with the identification of current and potential risks. These risks might happen in the future bringing a strong impact on not reaching the main objectives in the defined time and cost. The model has been tested by conducting a case study in food sector. A current state map was built using both models, traditional VSM and VVSM. The results showed the effect of variability and uncertainty on the total cycle time (CT) and lead time (LT) values, where the traditional VSM failed to show it by being a static tool. Comparing the results of both models show the differences in presenting the real state of manufacturing environment..

  Penelitian ini ditujukan untuk menganalisis pemborosan produksi produk Jala Ikan KKP menggunakan lean manufacturing di PT. Indoneptune Net Manufacturing dengan memetakan aliran produksi dan menganalisisnya menggunakan value stream mapping (VSM). Analisis terhadap pemborosan dengan metode VSM dilakukan karena VSM dapat memetakan aliran informasi dan material dari awal sampai akhir dari value stream pembuatan suatu produk. Sehingga dapat dilihat proses mana saja yang merupakan pemborosan. Adapun VSM yang dibuat adalah current-state VSM karena dapat merepresentasikan kondisi saat ini dari aliran produksi yang ada. Hasil yang didapatkan setelah dibuat current-state VSM adalah aliran produksi produk jala Ikan KKP melewati proses spinning, ring roupe, netting dan finishing yang memiliki sub-sub proses yang berbeda. Dari setiap sub-proses tersebut dipetakan nama proses, jumlah waktu cycle time dan changeover time, level inventory, waktu kerja tersedia dan jumlah operator. Penganalisisan pemborosan dilakukan pada setiap sub-proses untuk dapat mengetahui nilai tambah proses tersebut terhadap produk utama yang sedang dikerjakan pada setiap tahapan proses yang berlangsung. Kesimpulan yang didapat yaitu pemborosan yang terjadi di departemen spinning salah satunya adalah delay time karena persiapan sebelum proses peleburan, waktu tunggu karena persiapan proses twist di departemen ring roupe, transportasi berlebih sebelum proses tatekan dan pengerjaan ulang di hoshu 2 di departemen finishing.

PT. IE is engaged in the business of making Lighting and Lampposts. Based on observations and interviews, there are still some wastes that arise in the flow of the production process, among which there are still many wastes of waiting time, transportation, movement and inventory. These wastes cause the product completion time to be longer and the resulting quality decreases. To eliminate or reduce waste, it is necessary to apply Lean Manufacturing. Lean Manufacturing is a systematic approach to eliminating waste and changing processes by identifying and reducing waste with continuous improvement and striving to create a production flow along the value stream by eliminating all forms of waste and increasing the added value of products to customers. From the Pareto diagram, it is found that transportation waste has the highest percentage of 26.21%, waiting time is 21.38%, motion waste is 19.31% and waste inventories are 15.17%. while the results of the Value Stream Mapping Current State Map mapping obtained a production lead time of 7,680 seconds and a total cycle time of 6,660 seconds and a PCE Current State Map value of 53.09%. Identify the root causes of waste using Fishbone diagrams, 5 Why Analysis, 5W+1H, Fault Tree Analysis and FMEA. After corrective actions have been taken, based on the Value Stream Mapping Future mapping there is a decrease in production lead time to 5,220 seconds and a decrease in total cycle time to 4,860 seconds and an increase in PCE Future State Map to 68.10% so that there is an increase of 15.01% which shows The company's production process has become more Lean.PT. IE bergerak dalam bisnis pembuatan Lighting dan Tiang Lampu. Berdasarkan observasi dan wawancara, masih terdapat beberapa pemborosan (waste) yang timbul di aliran proses produksi di antaranya masih banyak terjadi pemborosan-pemborosan waktu tunggu, transportasi, gerakan dan inventori. Pemborosan-pemborosan tersebut menyebabkan waktu penyelesaian produk menjadi lebih lama dan kualitas yang dihasilkan menurun. Untuk menghilangkan atau mengurangi pemborosan diperlukan adanya penerapan Lean Manufacturing.Lean Manufacturing merupakan pendekatan sistematik untuk mengeliminasi pemborosan dan mengubah proses dengan cara mengidentifikasi dan mengurangi pemborosan dengan perbaikan kontinu dan berupaya untuk menciptakan aliran produksi sepanjang value stream dengan menghilangkan segala bentuk pemborosan serta meningkatkan nilai tambah produk kepada pelanggan. Dari diagram Pareto ditemukan waste transportasi memiliki persentase paling tinggi sebesar 26,21%, waktu tunggu  21,38%, waste motion 19,31% dan waste inventories 15,17%. sedangkan hasil pemetaan Value Stream Mapping Current State Map diperoleh production lead time selama 7.680 detik dan total cycle time selama 6.660 detik serta nilai PCE Current State Map sebesar 53,09%. Identifikasi akar permasalahan pemborosan menggunakan diagram Fishbone, 5 Why Analysis, 5W+1H, Fault Tree Analysis dan FMEA. Setelah dilakukan tindakan–tindakan perbaikan, berdasarkan pemetaan Value Stream Mapping Future ada penurunan production lead time menjadi 5.220 detik dan penurunan total cycle time menjadi 4.860 detik serta ada peningkatan PCE Future State Map menjadi 68,10% sehingga ada peningkatan 15,01% yang menunjukan proses produksi perusahaan telah menjadi lebih Lean.

Abstract Background: The peripherally inserted central catheter implantation and maintenance process was optimized at Shanghai Fu Dan University Cancer Center using lean-based methodology. Problems addressed were coping with capacity limitations and streamlining the process of patient care to reduce potential complications associated with delays in catheter administration. These clinical processes were evaluated with regard to pretreatment areas—such as booking, waiting, and patient education—and solutions were recommended to the problems that were identified. Methods: Lean methodology was used under actual clinical settings to improve the clinical process, using observations, patient surveys, interviews, data analysis, and a kaizen workshop. Three tools were applied from lean methodology: value stream mapping, bottleneck calculation, and fishbone root cause analysis. The philosophy of kaizen was used to enhance teamwork, boost morale, and encourage all members of the frontline nursing team and administration leaders to contribute ideas and suggestions for improvement. Results: A value stream map and a redesigned future value stream map were plotted at the workshop to identify problems related to inefficiency and waste and to aid in proposing solutions. Implementation of these solutions resulted in smooth and steady patient distributions on days with the largest patient volume during a typical week and an increase of 30% in the number of patients that could be seen in a week. Conclusions: The economic methodology of lean manufacturing, especially value stream mapping, can be a powerful tool for visualizing and better understanding processes to reduce waste and reengineer a standardized workstream in settings where peripheral intravenous central catheters are placed.

This paper studies the relationship between Lean paradigms and the Physical Internet (PI). Lean thinking is a philosophy that allows one to obtain the right amount of the right items in the right place at the right time; it seeks to minimize waste and is flexible to change. In fact, applying Lean not only helps to reduce costs, but it also adds value and improves results across the supply chain. By using a value stream map, we can map the process from the supply chain to the customer, while trying not to add value activities. Such activities include excessive production, overstorage, waiting times poorly adjusted to needs, defects and rejects that require reprocessing, and, finally, unnecessary transport and movements. Storage, waiting times, and unnecessary transport and movements are at the core of the PI. A value stream map can also help to identify empty transport and unnecessary CO2 emissions. This study analyzes value stream mapping as a tool that can enable the objectives of the different Alliance for Logistics Innovation through Collaboration (ALICE) roadmaps for logistics innovation to be achieved, and can also allow PI principles to be reached on the established dates.

Working Efficiency

Fierce competition encourages companies to make continuous improvements to achieve better working efficiency. One method to improve the working efficiency is using the concept of lean manufacturing. The efficiency of the existing work in PT. Rimba Kencana is still not good because there are many processes that are not uniform and because of that, production lead time is increased. By using value stream mapping and value stream analysis tools (VALSAT), the production processes in the company are mapped into the current state mapping and future state mapping. In the current state mapping, the total value of production lead time is 59.49 days and the value of process cycle efficiency (PCE) is 0.013%. After doing improvement on welding department, the total value of production lead time decreased to 48.22 days and the value of process cycle efficiency becomes 0.016%.
