“…O presente estudo tem como foco principal melhorar assertividade quanto ao volume de produção em uma empresa de óleo lubrificantes considerando a previsão de demandas a ser elaborada. Para que as empresas possam se ajustar e se programar, é preciso equilibrar demanda, produção, distribuição, compras e finanças, visando atender às necessidades dos clientes (Bozutti; Esposto. 2019).…”

O objetivo deste trabalho foi avaliar a previsão de demanda utilizando métodos matemáticos comparando com a demanda requerida por produtos de uma empresa. Tratou-se de um estudo de caso, em uma distribuidora de óleo lubrificante de motores. Caracterizou-se como pesquisa explicativa, aplicada e abordagem quantitativa. Foram utilizados relatórios mensais do período de abril de 2021 a julho de 2022. Os dados foram compilados no MS Excel sendo utilizados os métodos matemáticos de previsão de demanda da média móvel simples e suavizamento exponencial. Para acurácia do modelo empregado foi utilizado o desvio médio absoluto (MAD) e para o monitoramento da técnica de previsão foi utilizada a tendência de viés. A visão geral dos resultados encontrados mostrou que a utilização do método de previsão de demanda pela média móvel e por suavização exponencial, com coeficiente de 0,1, podem ser consideradas opções no processo de previsão com utilização de séries históricas.

Because of its extremely high strength to weight ratio, 7075 aluminum alloy is used for highly stressed structural parts including aircraft fittings, gears and shafts and various other commercial aircraft, aerospace and transportation equipment. In the case of cutting aluminum alloys, the chip breakability is the most important feature to ensure reliable operation in automated machining. In this study, in turning of 7075 aluminum alloy with a high-pressure coolant supply, the chip configurations, and the mass and thickness of chips were experimentally investigated. The following results were obtained:(1) In the case of a cutting speed of 5.0 m/s, a feed rate from 0.05 mm/rev to 0.50 mm/rev and a depth of cut from 0.1 mm to 3.0 mm, chips were not broken at a feed rate of 0.15 mm/rev or less with the conventional coolant supply. With a high-pressure coolant supply, the combination area of feed rate and depth of cut in which chips were broken was wider than that with the conventional coolant supply. With the high-pressure coolant supply at a coolant pressure of 7 MPa, there was a combination area of feed rate and depth of cut in which chips were not broken. However, chips were broken in all areas at a coolant pressure of 20 MPa.(2) In the case of both the high-pressure coolant supply, which has a coolant pressure of 7, 14 or 20 MPa, and the conventional coolant supply, the thickness of chip increased with the increase of the depth of cut. And, the thickness of chip did not change depending on the cutting method, namely the high-pressure coolant supply cutting method and the conventional coolant supply cutting method.

Purpose Supply chain vulnerability (SCV) analysis is vital for manufacturers globally because it creates a pathway for building resilient supply chains in uncertain environments. This study aims to identify drivers of SCV in the Indian manufacturing sector. Design/methodology/approach Sixteen drivers were identified from the literature review and followed by expert interviews. Interpretive structural modeling was used to determine the hierarchical structural relationship among identified SCV factors. Findings It was found that risk is not a board room agenda. Misaligned performance measures with incentives and lack of risk dashboard are the causal factors of SCV. Supply chain security, centralized production and distribution and lack of trust in the supply chain were driven factors. Originality/value This provides new insights to assess and prioritize initiatives for supply chain sustainability in terms of continuing business operations. The structural model provides a systemic view of SCV and helps reduce vulnerability.
