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 aim of this study is to analyze the existing production line in the automotive industry and proposed a layout of improved production line in the manufacturing process and obtain the optimum rate of production time. Thus, line balancing method and Yamazumi Chart was utilized to analyze the current and proposed production line. The collection of the data of the existing production line was conducted at one of the automotive company in Malaysia. From the analysis of current production line, two improved layout were proposed and evaluated. The proposed layout was selected based on a balanced production line and ability to meet customer demand. A balanced production line will ensure smooth process and eliminate wastage during operation

Value Stream Map

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.

This paper aims to demonstrate how the adoption of a continuous improvement program, based on lean manufacturing tools, can benefit the production of automotive filters for heavy vehicles, considering improved productivity and reduced operational waste, with a consequent increase in effectiveness and cost reduction. In this study we used the lean manufacturing tools, mainly kaizen and value stream mapping. During its development, the application of a kaizen project in a production line of automotive filters for heavy vehicles, aimed obtaining increased productivity and better distribution of physical space, through the reduction of rework time, reduction of downtime due to maintenance and reduction of setup time. The use of lean manufacturing tools, through the instruments presented in this study, guaranteed the viability of improvements in the productive sector. This work allowed the observation of a consistent improvement in production capacity, with productivity increase, through the improvement of the operational time and reduction of time of waste. The best distribution of physical space and the best arrangement of items used by the production process were also achieved through the consolidation of two production lines.

Abstract Objective: This work aimed to analyze how the Lean methodology has caused changes in organizational processes in a logistics company.Methodology: A descriptive and qualitative research was carried out in one of the branches of a large logistics operator located in the city of Vinhedo (SP). Questionnaires were applied and interviews were conducted with logistics experts, organization leaders, Lean Manufacturing managers and operators, coming to a total of 100 respondents, including organizational change factors such as Kaizen application for process improvement, 5S's for organization and cleaning and Kanban for production control.Results: It was evident that factors such as productivity, quality, organization, among others were factors for the implantation of the methodology in the company.Corporative results: The results revealed that after the implementation of Lean management, there were changes such as a better understanding of the proposed methodology, reorganization of processes and gain in productivity and quality, thus raising the level of competitiveness of the organization. Keywords: Organizational change, Lean Manufacturing, Logistics.
