In HMLV manufacturing, assembly mistakes by operators are common due to the ever increasing product variability and complexity. If mistakes can be detected early-on in the design process, product designers can reduce the possibility for mistakes. We present an algorithm to automatically detect and evaluate potential misplacements of parts that need to be fastened. Evaluation starts from a product CAD and returns the risk of misplacement as well as visual feedback on possible misplacements. An implementation with FreeCAD of our algorithm is illustrated on different use cases. [ABSTRACT FROM AUTHOR]

This research sought to improve the assembly process, specifically from the desktop computers of the Infotec company, from the implementation of lean tools that allow diagnosing, measuring, and implementing new improvements or modifications in certain stages in order to improve both the level of service and the lead time of the total process. Each stage of the process had to be analyzed together with the company's technicians in order to obtain information on the current situation. Among the main findings, the lack of updated work tools, poor organization of the workshop and a moderate amount of lead time were identified, this through the use of the Pareto Diagram, DOP, VSM, DAP and photographic evidence. In addition, a high expense was found in complaints that represents 30% of the fixed costs, which corresponds to the internal failures of the computer, due to the poor assembly of the components, the overtime, and the poor organization of the workshop. Therefore, the lean tools used were Six Sigma, SMED and Poka Yoke. These allowed to propose new improvements and modifications both in the assembly process and in the work area. The Arena software was used to capture the current situation and later a new one, with the improvements implemented, evidencing an improvement of approximately 20 minutes. This investigation had certain drawbacks at first, as the company made it difficult to collect data to obtain the current situation. However, it was managed to settle it through negotiation.

In recent years, there has been a considerable increase in the demand of the plastics industry; therefore, many SMEs have not been able to cover their demands due to production problems, since there is a high number of unproductive hours in unnecessary movements, machine stoppage, and poor machinery maintenance planning, among others. The problem that could be identified and that occurs in most SMEs in the plastics sector is low availability due to unproductive times. The purpose of this article is to reduce downtime in production and consequently increase the OEE, since this represents a loss of money for the company, especially in the injection process. Therefore, the idea is to implement the Lean Manufacturing model, which is validated with its TPM, 5s, ErgoSMED and Poka Yoke tools, in addition to the SLP implementation. To validate this improvement proposal, the Arena simulation software was used in a company in the plastics sector, since it will be possible to obtain a reduction of unproductive times by 20%, reduce travel times by 25%, reduce labor disorder in jobs by 15%, and in general increase availability by 12%, thus increasing the OEE indicator by 20%.

As one of the internet service providers ISP, Telkom Indonesia with IndiHome products cannot avoid customer complaints. In Tangerang's Mekarjaya industrial area, IndiHome complaints reach 14 percent per month. The purpose of this study is to reduce IndiHome complaints with the six sigma DMAIC cycle method. Other tools for analyzing this problem are Pareto Diagrams, Cause and Effect Diagrams and FMEA. IndiHome complaints that were prioritized for improvement were complaints because they were unable to connect 59.4 percent and complaints about intermittent internet connections 35.8 percent. In the improvement phase, poka yoke is implemented as a preventative measure in quality control. After the implementation of the six sigma IndiHome complaints decreased to 7% per month with a level of six sigma 3.47 and this research also succeeded in reducing the cost of repairing IndiHome services from IDR 7,888,889 to IDR 1.666.667 per month which means it changed 78.8% per month.
