The Lean Tools and Elements most used in Literature - Application of PROKNOW-C for Selection and Analysis of a Bibliographic Portfolio

2023-09-22T17:33:12+00:00

Abstract: The purpose of this article is to identify Lean tools, techniques and practices used in the implementations of manufacturing organizations globally and to select the most used ones. To better illustrate the study, the methodology of bibliometric review was used, through the Knowledge Development Process-Constructivist (Proknow-C), encompassing three steps: selection of the portfolio of articles; bibliometric analysis and systemic analysis. The studied portfolio revealed that there are many Lean tools, practices and/or techniques used that are repeated in successful implementations. In total, 29 journals were reviewed and it was concluded that the elements: Total Quality Management, Training, 5S, Just-in-Time, Value Stream Mapping, Standardization, Types of waste, Ergonomics, Leadership and Team Development, Multifunctional teams stand out with the number of citations within the portfolio, having 50% representation in the portfolio, so future studies related to determining which Lean tools and techniques to apply in organizations will benefit from this research

Lean Supply Chain Management: Insights from bibliometric analysis and literature review

2022-12-18T20:00:53+00:00

The covid-19 pandemic has impacted many countries and with it arose a growing concern of organizations about the vulnerability and low resilience of global supply chains. The incorporation of lean manufacturing in the supply chains enables the systematic reduction of activities that do not add value in an organization and within a chain could improve business performance, which can be widely extended between areas. Thus, this paper aims to investigate the advancement of knowledge about the lean supply chain through bibliometric indicators of scientific production and literature review. Among the research results, the number of publications increased over the years (1996-2021), and the countries that published the most on the topic are Brazil (46 documents), Malaysia (42), and the United States of America (40). The most applied tool was the Value Stream Mapping (VSM). As for future research, there is a need to propose more applied and comprehensive research; study the impact of lean on the supply chain; evaluate the Lean Supply Chain implementation process, and study the relationship between sustainability and Lean Supply Chain Management.

Technological roadmap integrating TPM and BIM in the management of building maintenance of federal universities

2023-09-19T20:50:50+00:00

Planning of maintenance activities is the basis for the effective operation of service and restoration of public buildings. Currently, there are technological tools that can help to improve building management and maintenance, such as BIM (Building Information Modeling) and TPM (Total Productive Maintenance) the integration of these two concepts can bring significant gains to building maintenance. This work developed a technological roadmap integrating BIM and TPM, such as a tool to improve building maintenance management, focusing on reducing maintenance costs and prioritising preventive maintenance. This research has been developed through a systematic literature review, followed by the elaboration and application of the Roadmap, which evaluates after application in a pilot project at a federal university. The results have shown that the incorporation of the Roadmap into the routine of the maintenance sector provided higher control by the management, reducing corrective problems and extending the useful life of machines and equipment. The acceptance of the team involved in the process was positive, demonstrating the proposed project's potential. This study concludes that using the technological Roadmap, integrating BIM and TPM, proved promising and coherent with the expectations for building maintenance management. In addition, it offers a guide to help the application and use of the Roadmap in other institutions, with future perspectives to expand the impact of this approach on building maintenance management in different environments. Therefore, this research represents a relevant contribution to federal Universities, providing a technological tool to optimise building maintenance management.

Redução de desperdícios de produtos “in natura”

2023-09-22T17:35:22+00:00

The application of Lean tools makes it possible, among other things, to improve processes in general. However, before its application, the diagnosis of the situation in which the process or production system is found must be well listed. Lean as a Philosophy presents a number of benefits and has a recognized degree of applicability. In this case, the objective in question was to reduce the volume of "in natura" product wasted in the bottling line (production). In order to adjust the process related to item M150, a series of actions were established, which are described in the item “Action Plan”. After applying the aforementioned action plan, the partial results obtained were a 3% reduction in in natura product waste in the bottling stage (Jan/Apr 2023); creation of Standard Operating Procedure for line M1; mechanical improvement in the M1 filling machine (Poka-Yoke installation study); and, training with operators to identify bottlenecks in filling. In addition, a better allocation of inputs was noted in the product preparation phase.
