Namibia is characterized by a fragmented health-care system that has led to data inconsistencies and duplication of efforts. It has also become costly to health-care institutions to maintain these fragmented, standalone systems. This study examined how enterprise architecture (EA) can be applied to guide the integration of health information systems (HISs) in the Namibian health-care context. A qualitative approach was applied to collect data from two cases using semi structured interviews and an interpretive approach in the analysis. From the analysis, the constructs of requirements clarity, information systems and technology (IS/T) project management, systems documentation, and communication were discovered to influence the development and integration of HISs. Applying these constructs, the study developed an EA guide for the development and integration of HISs. The study recommends that future studies consider developing similar architecture using a quantitative approach and possibly validating the developed guide using a quantitative approach.

This research addresses the pressing need for sustainable practices in aquaculture, which faces challenges, like environmental degradation. The study aims to evaluate the effectiveness of an intelligent aquaculture system (IAS) in improving key performance indicators in shrimp farming. Methodologically, it focuses on a specific shrimp farm divided into 10 breeding zones, with the number 3 area selected for experimentation. Data on environmental parameters and performance metrics were collected for comparative analysis against traditional practices. Results showed significant improvements: The IAS achieved a feed conversion rate of 90.22% and a growth rate of 50 g/week, outperforming traditional methods. Additionally, it exhibited lower disease incidence and mortality rates, indicating enhanced safety. The study concludes that IASs can substantially improve operational efficiency and sustainability, offering valuable insights for the future of aquaculture practices.

This study explores the optimization of centralized inventory systems through lateral transshipments, addressing supply chain disruptions caused by unpredictable demand. Lateral transshipments, which involve reallocating stock among retailers at the same distribution level, were investigated as a cost-effective and service-enhancing alternative to traditional emergency restocking methods. Using simulation and optimization techniques, we analyzed various transshipment policies, including Complete-Pooling and Partial-Pooling, across multiple scenarios. Our findings highlight that Partial-Pooling with an optimized threshold outperformed other policies by balancing collaboration and efficiency, reducing total costs, and improving service levels. The results underscore the importance of hybrid transshipment strategies, particularly for high-demand and cost-sensitive inventory systems. The research provides actionable insights for supply chain managers how tailored transshipment policies enhance centralized system overall supply chain resilience, profitability, and customer satisfaction.
