Managerial model and process for set-based design

Tese (doutorado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia Mecânica, Florianópolis, 2023.O Lean Product Development (LPD) representa o caminho para uma organização Lean. O LPD é complexo e exige um conjunto de elementos, que são muito difíceis de adotar. Soma-se a esse cenário uma base de conhecimento incipiente e a falta de fundamentos teóricos e práticos consistentes, sendo a Toyota o único caso de combinação bem-sucedida de ferramentas e práticas para o desenvolvimento Lean de produtos. Set-Based Design (SBD) é a espinha dorsal do LPD, representando seu elemento mais fundamental, orientando toda a cadência e fluxo do projeto. No entanto, sua complexidade constitui a principal barreira para a disseminação do LPD, pois mais do que apenas uma prescrição de atividades está por trás de seu sucesso. A SBD preconiza a experimentação além do projeto para aprender com o processo ao invés de buscar eficiência operacional. Como resultado, encontra mais resistência entre os desenvolvedores, pois sua implementação consome muito mais recursos do que as estratégias tradicionais. Esta Pesquisa é motivada pela necessidade de avançar em SBD, abrindo caminho para casos de sucesso de LPD nos mais variados ambientes e produtos. Esta Dissertação tem por objetivo apresentar um modelo e processo gerencial para a SBD, orientando sua implementação e organizando o conhecimento sobre esta área de estudo. Primeiro, uma revisão aprofundada da literatura foi realizada para identificar o estado da arte atual. A partir disso, foram identificadas oportunidades sob uma perspectiva gerencial e diretrizes foram derivadas para a proposição de um modelo e processo gerencial para a SBD. Por fim, a proposta foi estudada no desenvolvimento de produtos por meio de pesquisa-ação. O desdobramento e definição do valor, trade-off-curves, estratégia de desenvolvimento híbrido e o Toyota Kata aplicado ao desenvolvimento de produto formaram uma estrutura para projetar o produto de maneira integrada, construindo conhecimento para tomar decisões lentamente, apoiadas em dados. A separação dos subsistemas em domínios ajudou a concentrar esforços e recursos nas partes mais críticas. Os insights gerenciais desta Dissertação podem auxiliar os decisores a superar as barreiras para o SBD. Pode encorajar os profissionais a adotar o SBD, fornecendo uma perspectiva clara dos benefícios e caminhos de implementação.Abstract: Lean Product Development (LPD) emerged as the next step organisations must take toward a Lean Enterprise. LPD is complex to implement and demands a set of well-defined enablers, which are very difficult to adopt. Added to this scenario is the insipient knowledge background and lack of a consistent theoretical and practical basis, being Toyota the only case of a successful combination of lean tools and practices for well-succeeded product development. Set-Based Design (SBD) is the backbone of LPD, representing its most fundamental element, guiding all design cadence and flow. Nevertheless, the complexity of SBD implementation forms the major barrier to LPD dissemination since more than just a prescription of activities is behind its success. SBD preconises experimentation beyond the project to learn with the process instead of seeking operational efficiency. As a result, it finds more resistance among developers as its implementation consumes far more resources than traditional strategies. This research is motivated by the necessity to advance in SBD, paving the way for successful cases of LPD in the most variated environments and products. This Doctoral Dissertation aims to present a managerial model and process for SBD, providing guidelines for its implementation and organising knowledge regarding this field of study. First, a comprehensive in-depth review of the literature was undertaken to identify the current state-of-the-art. Based on this, opportunities from a managerial and engineering-oriented perspective were identified, originating guidelines for the proposal of a managerial model and process for SBD. Finally, the proposal was studied in real-world product development through action research. Value deployment and definition, model-based trade-off-curves, hybrid development strategy, and the Toyota Kata applied to product development formed a framework for designing the product in an integrated manner, building knowledge to make decisions slowly, supported by data. Separating subsystems into domains assisted in focusing efforts and resources on the most critical parts. The managerial insights from this Dissertation can assist decision-makers in overcoming barriers to SBD adoption. It encourages practitioners to adopt SBD by providing a clear perspective of benefits and implementation paths

A reactive agent-based decision-making system for SBCE

International audienceNowadays, manufactured products offer more and more personalization. This paradigm is in acceleration due to the emergence of mass customization proposed by industry 4.0. To cope with this demand, industry must design suitable products and adhere to a strict specification. Tools and process were proposed to manage product design, validation and manufacturing such as Set-Based Concurrent Engineering (SBCE). Project Manager in charge of this critical step is helped by metrics and indicators. However, visual aid, dynamic and adatative solution, capable to reply in real-time to a major project evolution does not exist. The aim of this paper is to present an approach for SBCE alternatives selection, based on the application of reactive multiagents systems. Multi-agents systems are an efficient approach for problem solving and decision making in dynamic context. The proposal is evaluated in simulation on drone design optimization
