<p>Increasing productivity and quality is one of the key to make company stay competitive. Lean<br />TPM approach is one of the way to increase productivity. Problem that usually occur at PT. XYZ is the<br />down time from each line of process production that causing actual production did not reach the target.<br />It is dominantly cause by material shortage, process defect, and machine breakdown. This purpose of<br />study is to develop a production productivity improvement model with Lean TPM approach by using<br />dynamic system. This study is started by measuring the Loss time value, OEE (Overall Equipment<br />Effectiveness) value, and making VSM (Value Stream Mapping) to see the flow of material and waste.<br />This is done to measure the actual condition. With this measurement, we can track which one cause the<br />highest % loss. After that, using the FTA (Fault Tree Analysis) to find the root cause of downtime and<br />waste produced. It needed to construct the existing dynamic model because the problem are complexs<br />and dynamic. In that model, analytical system is done to indentified and imitated the characteristic of<br />those complex systems and also to make the alternative troubleshooting repair solution.</p>

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.

Productivity is an important parameter for all small and medium scale manufacturing industries. Lean manufacturing emerged as production strategy capable of increasing productivity by identifying and eliminating non value added activities. This article deals with productivity improvement in a pre-assembly line of gearbox manufacturing company with a case study using lean concepts like process flow chart, process Gantt chart and time study. This paper illustrates using a case study on how a value stream mapping has to be carried out in a planet carrier pre-assembly line. Value stream mapping and work standardization are the key tools used in lean manufacturing and lean transformation. It makes the process smoother, helps in reduction of lead time and ultimately increasing the productivity. From the observed results it was found that, the productivity has been increased from 7 pieces to 10 pieces in the first step assembly when the proposed VSM was implemented. The second step processing time was reduced by the execution of proposed value stream mapping with TAKT time of 126 minutes and 165 minutes of processing time for demand of 10 pieces were achieved and the overall processing time has been reduced by about 24%.

Analysis Of Results

For many years, productivity improvement through value stream mapping and simulation has been studied in manufacturing industry where the flow of materials is visible and the work can be standardized. In recent years, the service industry has become a new arena for lean operations. Within the service industry, client-based companies have distinct challenges in streamlining their process, as it may not be feasible to standardize the needs of different clients. This thesis focuses on a case from a client-based company in the area of graphic communications and brand point management services. The thesis examines the application of lean principles towards a set of subjective processes and provides directions for improving productivity. Some lean methods utilized in the study include creating process flows, conducting operator interviews to back-up the process flow, collecting data such as processing time and creating a detailed values stream map of the retail packaging process in order to analyze any necessary areas of improvement. Value stream mapping has been used to identify the areas where the non-value-added tasks can be reduced, and simulation models have been used to imitate and predict the company's different scenarios in dealing with bottlenecks, different kinds of wastes, and to assess potential areas for improvements. The analysis of results indicates that it is necessary to have two different streams of the processes; one for a team-based job and another one for a non-team-based job. The proper touch points from each department have been found and value-added and non-value added times have been determined in order to create the current-state. Furthermore, future-states have been created with some recommendations kept in mind to validate the time savings. The results have been verified through a simulation analysis.

PT PLB (pseudonym) is a company that produces household appliances and kitchen utensils. The country kettle is one type of product made by PT PLB. The productivity of the country kettle production line decreased by 56%. This was due to defective products. The largest percentage of defects in-country kettle products occurred in the spinning process of 40.18%. This study aimed to identify the causes of defects in-country kettle products and how to overcome them by designing improvement proposals. Lean manufacturing principles were used to evaluate the problems that occur. There were three types of lean manufacturing tools used in this study: Value Stream Mapping (VSM) and 5Ways. VSM was used to describe and identify value-added activities, non-value-added activities but necessary, and non-value-added activities so that the production process becomes lean. The root cause analysis was performed using the 5 Whys method. Unskilled workers and non-standard material types between suppliers are the highest contributors to defects in the spinning process. Based on this, this research was focused on improvements made in the spinning process. Proposals for improvements to the causes of the problems found are standardization of work procedures, standardization of supplier specifications, and arrangement of semi-finished goods and/or supplies. Based on the company's results, the proposed standardization of work procedures and arrangement of semi-finished goods and/or supplies may be implemented in the company. Meanwhile, the proposal for selecting suppliers is not feasible due to company limitations
