Profit Optimization for a Manufacturing Supply Chain Under Carbon Emission and with Inventory - Price Based Demand

Highlights: A manufacturing supply chain dealing with decaying inventory is studied with three production sub-cycles. Price-based demand, the Weibull degradation rate and carbon tax policy are taken into account. Price, carbon emission factor, cycle length and production period are decision variables to increase profit. Goal: The research work aims to maximize profit for a manufacturing supply chain dealing with deteriorating inventories. To maximize profit, the optimum value of production cycle length, total cycle length, price, and emission factor were studied. Projeto/ Metodologia/ Abordagem : Uma cadeia de suprimentos de manufatura é estudada a fim de maximizar o lucro. Todas as suposições são apresentadas matematicamente como um modelo de função de lucro. Usando um problema numérico, a análise e as implicações práticas do problema de otimização projetada foram demonstradas. Finalmente, uma conclusão eficiente é construída para demonstrar a aplicabilidade do modelo de lucro de otimização com base na análise de sensibilidade. Resultados: Conclui-se que para maximizar o lucro, a duração do ciclo, o preço e a emissão de carbono precisam ser minimizados e maximizados a duração da produção. Conclui-se também que à medida que o preço aumenta a demanda diminui que diminui o lucro. Limitações da investigação : O modelo de lucro é projetado sob certas premissas, como taxa de deterioração, taxa de demanda, ciclos numéricos, portanto, o modelo é aplicável a tais condições. Implicações práticas : Este trabalho de pesquisa pode ajudar a gerenciar a cadeia de suprimentos de manufatura para a deterioração dos estoques para maximizar o lucro com o mínimo de emissão de carbono. Originalidade / valores : O presente trabalho de pesquisa é motivado pelos problemas dos fabricantes e organizações que lidam com estoques deteriorados

Impact of Carbon Emission Policy on Fresh Food Supply Chain Model for Deteriorating Imperfect Quality Items

Carbon emissions can be decreased by adopting the carbon cap-and-alternate policy. The current study suggests a carbon buying and selling mechanism for things that are deteriorating or of poor quality while taking into account chilled logistics services in a fresh food supply chain. In addition to deliveries of perishables, suppliers also provide retailers with chilled logistics services and carbon emission certificates for excess inventory. The retail price, the cost of chilled strategies, and the contributions to various carbon trading options—such as internal carbon trade, external carbon exchange, and carbon exchange both internally and externally for the destruction of low-quality goods have all been evaluated in this paper. The store network members give estimating systems to new food, emanation permits and refrigerated planned operations administrations. We likewise uncover the connection between carbon purchasing and advancing and refrigerated strategies administrations and test out their joint effect on the provider retailer's helpful dating. Store network donors are also encouraged to participate in the carbon exchanging mechanism, which benefits from more sophisticated asset utilisation and more ruthless stockpile chains. The numerical examples have helped to validate the results. In the end, a thorough sensitivity analysis has been provided

Strategic supplier relationships and supply chain resilience: is digital transformation that precludes trust beneficial?

Purpose The purpose of this study is to investigate the role that communication, trust and digital transformation can play in the relationship between joint problem-solving and supply chain resilience. More specifically, the authors try to examine the possibility of digital transformation as a replacement for trust within a joint problem-solving context. Design/methodology/approach A survey instrument was developed and administrated to manufacturing firms within the United Kingdom and the United States. Based on data collected from 291 senior managers, multiple linear regressions were conducted through a customized process model to test the proposed hypotheses. Findings The results point to the actual impact of digital transformation being far more complicated than the initial benefits that it appears to bring within a supply chain. Thus, technology is only effective when applied within the right context. The authors showcase that the trio of digital transformation, trust and joint problem-solving can be highly valuable to establish supply chain resilience and that further investigation on the interrelationships between these concepts is warranted. Practical implications Manufacturing firms that aim to adopt new technologies should not consider advanced digital technologies as an alternative to trust. While digital transformation can improve resource sharing and integration, governance mechanisms–such as trust–will remain the cornerstones of strategic supplier relationships. Therefore, supply chain partners must strive to achieve a balance between trust and the right type of digital technology. Originality/value This study contributes to the growing literature focusing on the role that digital transformation can play in developing supply chain capabilities. It adds an early empirical insight on the role of technology and governance in joint problem-solving and supply chain resilience
