“…M-Haidar and Nasr [31] discussed the reworking and screening processes at the end of production. Silva et al [32] focused on the delivery performance of the TKS, GKS, and POLCA production systems and achieved short delivery times as well as on-time delivery. A make-to-stock strategy was adopted in the TKS system, directly related to the make-to-order policy.…”

Several industries are facing many challenges in their production systems due to increasing customer demand. Customer demand is growing for products with innovative features that are flexible, good quality, and appealing. This paper presents a flexible production-inventory system that produces multiple parts of a product. Defective products may be produced during the production process. Those defective products are remanufactured immediately after inspection. Limited budget and space constraints are considered, along with product assembly. Based on different distribution functions, non-linear equations are calculated using the Kuhn–Tucker optimization technique. Numerical examples, a graphical representation, and sensitivity analysis are presented in this paper. The solution procedure evaluates the minimization of the total investment based on the χ2 distribution. This study examines electronic products those are more likely to be defective rather than perfect during production.

“…The main objective of the lot-sizing methods is to determine the size of the production or purchase batches, which minimizes the costs (Araújo, 1999;Marques, 2013). Moreover, specific lot-sizing approaches, along with other Material Management Policies (M&MMP) and techniques, such as those based on JIT (Varela et al, 2018;Araújo et al, 2017) and Kanbans (Silva et al, 2017;Salgado and Varela, 2010) can also be considered for production and purchase batches sizing and inventory management processes (Nunes and Vieira, 2016).…”

Goal: The main goal of this research is to analyse the behaviour of a set of ten lot-sizing methods applied to different application scenarios, within the context of more traditional MRP-based manufacturing environments and on JIT/ Kanbans oriented ones. Design/Methodology/Approach: After an extended literature review, a quantitative research method is used to provide a comparative analysis on the performance of the lot-sizing methods under different simulated application scenarios, with variations in demand and peaks of seasonality. Moreover, a final summary provides the error deviations for lot-sizing methods regarding increases in demand variations and seasonality indexes. Results: The study analyses lot-sizing methods and discusses benefits and risks associated to its use in application scenarios marked by a considerable variation in demand or peaks in seasonality. Limitations of the investigation: As the application scenarios did not explore variations in the ordering and stock holding costs, further analysis including these kinds of variations is encouraged. Practical implications: The findings of this research enable the enhancement of the conscience of industrial practitioners, regarding the selection of best suited lot-sizing methods for being applied on each kind of manufacturing scenario, regarding MRP or JIT/ Kanban environments. Originality/Value: Given the diversity of the existing lot-sizing methods, for instance, the heuristic ones, authors can find it quite difficult to select appropriate methods for solving their problems for each kind of application scenario. Therefore, the present study can provide useful knowledge to better support decision making in the lot-sizing domain.

“…Contudo, foram adicionadas algumas melhorias que serão apresentadas a seguir. O Kanban é um método de coordenação de ordens altamente eficiente em ambientes produtivos com baixa variedade de produtos e sistema de produção para estocagem (Make to Stock), como o caso apresentado no presente estudo (SILVA et al, 2017). Na produção Make to Stock os produtos são padronizados e fabricados de forma repetitiva, sem que o cliente participe de forma direta na definição do produto.…”

A metodologia lean tem sido implementada nas organizações para otimizar processos e diminuir os desperdícios, assim eleva a competitividade perante a concorrência e a performance da mesma. Para manter a fabricação enxuta, diversas ferramentas podem ser implementadas na organização, sendo uma delas o mapeamento do fluxo de valor (MFV). Desta forma, o presente estudo tem como propósito mapear o fluxo de valor da fabricação de produtos extrusados pet food e identificar os desperdícios para propor melhorias. O método de pesquisa utilizado foi o estudo de caso, que permitiu a análise aprofundada do processo produtivo em uma organização de grande porte. Com a aplicação do MFV obteve-se como resultado o mapa do estado atual e após a análise o mapa do estado futuro. As sugestões de melhoria incluíram sincronizar a produção ao adotar o Kanban e supermercados para introduzir o fluxo puxado de produção. Por fim, houve a redução do lead time de 13,8 dias para 6,13 dias e a quantidade de operadores de 17 para 12. A partir do estudo realizado, pode-se identificar lacunas para pesquisas futuras.
