Diagnóstico para implantação do mapeamento do fluxo de valor : uma análise aplicada no arranjo produtivo têxtil de Erechim – RS.

Abstract

This dissertation aimed to conduct a diagnostic analysis of companies within the Textile Local Productive Arrangement (APL) of Erechim, utilizing the concepts of Value Stream Mapping (VSM) variations in an integrated manner. The objective was to facilitate the application of VSM, making processes more sustainable and generating improvement opportunities for companies in the textile sector. To achieve this, systematic literature reviews were conducted to identify the combinations of VSM with other tools and the existing variations of the traditional model. Subsequently, a diagnostic study was carried out with companies from the Erechim APL to assess their level of adherence to VSM variations. The study highlighted that combining VSM with Life Cycle Analysis, QFD, Fuzzy TOPSIS, and cost analysis, among other tools, demonstrated its capacity to identify bottlenecks and comprehensively reduce waste. Additionally, improvements in sustainability indicators, cycle time reduction, cost minimization, layout optimization, and process digitalization were observed as key benefits achieved. Based on this analysis, a framework entitled Integrated Value Stream Mapping (IVSM) was structured, designed for small and medium-sized enterprises (SMEs), integrating the objectives of these tools with conventional VSM. The review on VSM variations identified multiple adaptations of the traditional model, emphasizing that Sustainable Value Stream Mapping (Sus-VSM) is predominant across the four continents studied. Furthermore, the main indicators employed in these variations were analyzed, leading to the proposal of an integrated VSM model applicable to SMEs in the textile sector, combining concepts and metrics from five VSM variations. Finally, the diagnostic study revealed distinct levels of adherence to VSM variations, with Ergonomic Value Stream Mapping (Ergo-VSM) standing out, being adopted by 77% of companies. This finding indicates a significant emphasis on improving ergonomics in production processes, occupational health, and productivity enhancement. Conversely, environmental sustainability aspects showed a lower level of adherence, around 38%. Regarding digitalization, the study identified a gap that can be addressed to foster business growth. Additionally, an integrated VSM model was proposed for application in small and medium-sized enterprises in the textile sector. The model is composed of variations used as the foundation for diagnostic analysis.
