As melhorias introduzidas aumentaram a capabilidade do PDP da empresa tanto na análise do… Show more
“…CMMI suggests that it has two possible directions for process improvements based on the third party approaches: a whole company improvement based on maturity levels and a sector-specific improvement approach based on capability assessment (Chrissis et al, 2003). Some literature discusses capability-based improvements Schuh et al (2017), Barbalho and Rozenfeld (2013), Barbalho and Rozenfeld (2008), but generally, the concept of maturity assessment and improvement is more commonly applied (Schuh et al, 2017;Agca et al, 2017;Carolis et al, 2017). In other words, capability-based improvements tend to generate performance islands, as suggested by Vernadat (1996).…”
Goal: Industry 4.0 has the main purpose of turning the company into an agile organization and adapting continuously to the market's dynamicity. Thus, to reach this target, the business should be aware of its current readiness level and establish digital strategies to reach higher levels. This research aims to explore how improvements in industry 4.0 can improve companies' business processes.Design / Methodology / Approach: The present study is action research that initially identified the most suitable maturity model in Industry 4.0 in the scientific and practitioner literature. Furthermore, the chosen model was applied to a beverage manufacturer to evaluate its current maturity level. Some Industry 4.0 improvements were implemented on the warehouse as part of the company's digital strategy into which it was integrated the inventory management system with new digital solutions. Finally, interviews were conducted, and data was gathered from company indicators.
Results:The action research's conduct revealed its current status and how storage management contributed to its digital transformation process. A phenomenon of islands of improvement is discussed at the end.
Limitations of the investigation:Our main limitation is our case study approach. Additionally, more interviews crossing functional areas could bring additional elements about the perception of improvements that each functional group had at the implementation process. Practical implications: The case study suggests that maturity models' applications can generate the phenomena of islands of improvements. Managers must take this situation into account to plan digital transformation in the whole company.Originality / Value: The phenomena of the island of improvement is suggested to be a side effect of implementing industry 4.0 based on maturity models.

“…Os modelos de referência podem ser entendidos como diretrizes, procedimentos e critérios de decisão para que ocorra o sucesso no PDP (BARBALHO & ROZENFELD, 2013 Quando há possibilidade de geração de um produto novo, necessita-se ter atenção no processo de projeto que será utilizado, isso para que o produto incorpore todos os atributos que são indispensáveis para o cumprimento da tarefa a que se destina (REIS & FORCELLINI, 2006). Nesse sentido, conforme SCALICE et al (2012), vários autores relatam a importância de um correto e completo projeto das interfaces de um produto.…”
“…The study of BARBALHO & ROZENFELD (2013) demonstrated that the application of a reference PDP model might result in process improvement, reporting better indicators of time, cost and quality of the PDP.…”
Soy harvest matches seasons with shortage of dry matter supply for ruminant feeding in most Brazilian soy-growing areas. Agricultural machinery-producing companies must have market perception, observing new opportunities and developing equipment to meet costumers' needs. This paper aims to design, build, and test a device to collect soybean crop residues from the combine cleaning mechanism, consisting mainly of vegetable straw (chaff), and the other plant parts (stems) remain being deposited onto the ground. For equipment designing, we made use of the architectural design methodology proposed in the reference model for the agricultural machinery development process. The equipment was designed and built following the proposed methodology, then installed and put into operation in a John Deere 1165 combine. After initial testing and few adjustments, the device showed satisfactory chaff-collecting performance. The equipment consists of a screw conveyor assembled transversely to the combine and a centrifugal fan assembled on the side. The collected chaff is dumped into a trailer towed by tractor.KEYWORDS: ruminant feeding, soy chaff, agricultural machinery designing.
PROJETO E CONSTRUÇÃO DE UM EQUIPAMENTO RECOLHEDOR DE RESÍDUOS DA COLHEITA DE SOJARESUMO: Na maioria das regiões produtoras de soja do Brasil, a colheita dessa cultura coincide com um período de escassez de oferta de matéria seca para a alimentação de ruminantes. As empresas produtoras de máquinas agrícolas devem ter a percepção do mercado, observando novas oportunidades e desenvolvendo equipamentos para atender às necessidades de seus clientes. O objetivo deste trabalho foi projetar, construir e testar um equipamento para coletar os resíduos da colheita de soja, provenientes do mecanismo de limpeza da colhedora, constituído principalmente pela palha dos legumes (palhiço), eis que as demais partes das plantas (hastes) continuam sendo depositadas no solo. A concepção do equipamento foi realizada utilizando a metodologia projetual proposta no modelo de referência para o processo de desenvolvimento de máquinas agrícolas. O equipamento foi projetado e construído seguindo a metodologia proposta, instalado e colocado em funcionamento em uma colhedora John Deere 1165, após os testes iniciais, e alguns ajustes, apresentando desempenho satisfatório na coleta do palhiço. O equipamento desenvolvido consiste em um transportador helicoidal montado transversalmente à colhedora e de um ventilador centrífugo instalado na lateral. O palhiço coletado é transferido para uma carreta agrícola, rebocada por trator.PALAVRAS-CHAVE: alimentação de ruminantes, palhiço de soja, projeto de máquinas agrícolas.
