The lean manufacturing concept is a systematic minimization of waste and non-value activities in production processes introduced by the Toyota production system. In this research, lean manufacturing is implemented in a cement production line. Value Stream Mapping (VSM) is applied to give a clear picture of the value chain in cement production processes and to highlight the non-value-added in the shop floor. To begin, the existing VSM is constructed based on the information and data gathered during visiting and observing the manufacturing process in the firm. As a result, the excess inventory between workstations was identified as a major waste generation, hence, the proposed VSM conducts further improvement and makes action plans to alleviate the unwanted activities. Then, the takt time to ensure smooth material flow and to avoid any occurring delay or bottleneck in the production line was figured out. The supermarket pull-based production control is suggested to be adopted in the future map. Two pull production strategies are selected in this case. The first is applying the Kanban system to control the level of inventory between workstations. The other is the CONWIP approach to control the amount of work in process to the entire production line. The outcome of the proposed models indicates a decrease of the none-value time from 23 days in the current state to about 4 and 2 days in Kanban and CONWIP systems respectively, so the CONWIP was suggested as most efficient. Some suggestions for further research are also mentioned.

Today modular and off-site construction practices are widely used as a novel approach to residential and commercial building construction. Although this approach is known for its high production efficiency and low material waste, manufacturers are facing the challenge of fully differentiating their modular construction procedures from the conventional construction approach. Manufacturers are thus seeking to continuously implement efficient methodologies to improve their production line effectiveness, thereby enhancing their market competitiveness. This paper proposes a methodology enabling the modular manufacturer to overcome this challenge and increase their assembly line productivity by implementing building information modelling (BIM)-supported lean manufacturing concepts, with a particular focus on the importance of the upstream pre-assembly line. This technique was implemented on a case-study, a residential modular factory, and increased the production line productivity by implementing the Lean-assembly concept. This approach is supported by the information provided from an enhanced BIM model generated to deliver accurate resource quantity required at each assembly station.

PT. PAI is a footware company that produces sports shoes. The production process at PT. PAI, has a waste of 15.891%. To overcome the problems that occur, this study was conducted with the aim of identifying and proposing waste elimination. The method used is a lean manufacturing approach. One of the tools used is Value Stream Mapping (VSM) and Yamazumi Chart. The first stage to solve the problem is the identification of waste using the Waste Relationship Matrix (WRM), Waste Assessment Questionnaire (WAQ) and VALSAT. The second stage is carried out by designing the current Value Stream Mapping (VSM), designing the proposed improvements using the Yamazumi Chart to balance the production line and designing the Future VSM based on the results of the proposals that have been given. The result of identification using these tools is known that the biggest waste is waste in the process with a percentage of 15.891% followed by overproduction of 15.774%. Based on the calculation using VSM and Yamazumi Chart, elimination of waste can be done as much as 5.48%, reducing the number of workers by 32 people and reducing the number of work stations by 16 work stations

Keeping up the quality level in in a manufacturing environment has become an issue when trying to start the production of a new product which is in a ramp-up stage into a running production line ramp-down model. If production of the old model is ended too fast will make shortages in the customer supply, and will have excessive inventory numbers of the newer product. Trying the re-design in a production line to keep building the old model while incorporating the newer tends to create an undesirable impact on quality and productivity. Nowadays, continuous improvement methodologies like Lean and Six Sigma are used to solve this challenge. While Lean Manufacturing tends to be efficient for quick fixes, Six Sigma works better when there is plenty of time to conduct deeper statistical analysis. This chapter describes a combination of Lean Manufacturing speed with the Six Sigma analysis' power. Combined to maintain the quality and productivity of a production process during such conditions.

The lean manufacturing has been widely applied in the most of the industry sectors. Single Minute Exchange of Dies (SMED) is one of lean manufacturing tools that can be used to further reduce production waste. In order to ensure waste be effectively reduced, lean manufacturing has tools to achieve its goal. The first step is analysis of current state value stream map from the production line. The second step is the use of Single Minute Exchange of Dies to propose and carry out improvement actions in bottleneck process. In this study, the aerospace engine case production lead time was reduced from 9 weeks to 7 weeks by VSM method. The SMED method was applied to improve bottleneck’s setup time from 95.68 minutes to 76.97 minutes. The lean manufacturing tool can help factory to reduce inventory in the WIP.

<p>Pharmaceutical industry especially that move in generic products, have many kinds of products to be manufactured in its production lines with the shortest possible time. This condition causes the frequent of changeover process. This cause requires the company to further improve the effectiveness of the machine by reducing the time of changeover process in terms of setup and clean-up machine. In order to reducing the time of setup and clean-up activity use the method of approaches the SMED analysis method to reduce unnecessary motion waste (value added and non-value added derived from lean manufacturing). Before conduct the research, in the 5th production line was not in the Kanban system. So, it often occurs the changeover process. The longest changeover time is in the drying room. After that conduct the Time and Motion Study in order to know the detail setup activities in the drying room. This is due to problems in the working methods and environment factors. Based on data from observations made on the engine FBD, there are 49 activities comprising 44 internal activities and 5 activities that can be converted to an external. Then from 44 internal activities, only 43 were able to be combined activity of up to 11 activities. Results from this study is able to decrease setup time and clean-up on the machine FBD by 62.18%. Based on this result also, this can increase the productivity of the production line.<br />Keywords: Unnecessary motion waste, Lean Manufacturing, Value added, Non-value added, Changeover process, SMED.</p>
