Green Supply Chain Management Practices and Effects on Organizational Performance in Zambian Beverage Manufacturing Industry

Ethel Tembo Mwanaumo — 2023-11-30

Organizational performance is important because it directly impacts the overall success and sustainability of a business. This study aims to investigate the effects of Green Supply Chain Management (GSCM) practices on organizational performance in the Zambian beverage industry, using an embedded mixed methods model. Quantitative data was collected using a questionnaire from 32 participants out of 37 and analyzed using descriptive and inferential statistics using STATA Version 14.2. Qualitative data was collected from in-depth interviews with 9 Supply Chain Specialist and Industry Experts, selected based on availability, convenience and volunteering. The results show that Green Purchasing, Green Manufacturing, Green Distribution/Marketing, and Reverse Logistics each had a positive influence on organizational performance. Internal drivers had a significant and positive effect on organizational performance, while external barriers had a negative influence. Stepwise regression revealed that 14.9% of the variations in organizational performance were explained by the model, with internal drivers being the most significant factor. The study concludes that major benefits of applying GSCM practices are reduced production costs, good reputation with the municipalities and law enforcers, and long-term savings due to efficiency in production. The study recommends that companies should increase their knowledge of GSCM practices and engage in more sustainable practices to reduce production costs and prevent further environmental degradation. Future studies could include research in factors that can improve GSCM practices in the Zambian beverage manufacturing sector.

Topology Study of Milking Machine Based Parametric Modeling

Novi Sukma Drastiawati — 2023-11-30

The large market for cow's milk makes the order capacity for cow's milk high and will increase the milking process. In the production process, especially the milking process, people still manually use their hands, so fatigue often occurs, especially in people with more than 2 livestock. This causes the production process to be ineffective and the production results are also limited. Creating an automatic milking machine equipped with a milk can, a vacuum tube and a hose. Besides, a topology study will also be carried out based on the model of the machine. The three-unit component will affect the performance of the Milking Machine, especially the milk collector and milk can. Their size needs to be analyzed to get the optimum one. Optimization results for the topology of the milk collector bore diameter showed that the milk flow rate in the milk collector at a bore diameter of 9mm was 6,154 ltr/min, at a bore diameter of 14 mm was 26,566 ltr/min and at a bore diameter of 19mm was 66,128 ltr/min (conditions without being connected to hose). The shape of a milk can with a reduction of 30% from the initial weight, which is 3,358 kg to 2,350 kg, is owned by a milk can with the most optimal cone-dome tube shape. The difference in weight with the tube is generally 1,008 kg. The quantity flow when installed with a 2m long hose is 6,729 ltr/min

Supply Chain Management Practice and Competitive Advantage: Systematic Literature Review

Alemgenet Hailu Menesha — 2023-11-30

Supply chain management integrates activities through improved supply chain relationships to achieve sustainable competitive advantage. The major objective of the study is to review academic articles published previously concerning the relationship between supply chain management practices and competitive advantage to indicate a direction that could need further research. This review adopts the systematic literature review approach to identify studies conducted between 2002 and 2022. The review focused on summarizing the studies' major aspects and analyzing them by identifying themes. The paper identified 25 most impactful studies in this area. The finding indicates that most studies were empirical studies and used a quantitative research approach with an explanatory research design. The analysis of the papers demonstrated that the Resource-Based Theory, Dynamic Capability Theory, Resource Dependency Theory, Relational View, Knowledge–based Theory, and System Theory are among the major theories used as a foundation for the studies. Supply chain management dimensions such as strategic supplier partnership, customer relationship, information sharing, quality of information, and postponement are used to measure Supply chain management practices. Furthermore, price/cost, product innovation, time to market, delivery, and Dependability are used to predict Competitive advantage

Third-Party Logistics Practices in E-commerce of Nepal: A Narrative Study of the Supply Chain Professionals

Praveen Chaudhary — 2023-11-30

In recent years, the rapid growth of e-commerce has revolutionized the way businesses operate and consumers engage in commercial activities. This transformative shift has brought about unprecedented convenience and accessibility, enabling global consumers to shop for products and services from the comfort of their homes, including in Nepal. Simultaneously, the demand for the intricate web of operations behind these transactions (logistics management) has become paramount. And, in the realm of logistics, the notion of outsourcing by means, of third-party logistics (3PL) emerges as a pivotal strategy. Subsequently, this study embodies a pragmatic perspective through the qualitative study using the narrative approach thus by unstructured interviews with the select information-rich supply-chain service professionals in e-commerce companies employing the 3PL practices in their logistical fulfilments. The study illuminates on the circuitous reciprocity between 3PL strategies and the distinctive features of Nepal's e-commerce landscape filled with infrastructural challenges and urban- rural divide that co-exist with opportunities. The findings revealed that the core focus, reach, digitalization, financial viability, product safety, and logistical efficiency concerns influence the 3PL outsourcings. It also delves through the prevalent practices, challenges, and opportunities, and also optimization measures from the perspective of supply chain professionals, shedding light on the path forward for optimizing logistics for e- commerce, emphasizing the coherent need to incorporate the digital shift, customer-centricity, continual learnings and financial prudency, thus holds a significant importance.

Contribution of Lean Manufacturing on environmental performance in Moroccan Industry

Yassine Bouazza — 2023-11-30

In the context of globalized competition, sustainable development has become a crucial goal for manufacturers, necessitating a balance between economic, environmental, and social factors. The evolution of production system efficiencies and government policies has been pivotal in mitigating the environmental impact of manufacturing activities. This paper explores the role of Lean Manufacturing in enhancing environmental performance within organizations. It presents the concept, tools, and models of Lean Manufacturing, discussing its contribution to environmental sustainability. The paper bases its findings on a literature review and validates them through two case studies in Morocco. The first case study examines the implementation of Lean tools in a Tangier-based company, highlighting significant reductions in waste and energy consumption. The second involves interviews with managers from Moroccan automotive industries, revealing a positive correlation between Lean practices and environmental performance. The conclusion drawn is that Lean Manufacturing not only reduces pollution and energy consumption but also boosts productivity, thus aiding companies in becoming more profitable and environmentally responsible.
