Utilizing the Cobb–Douglas production function, we derive a comprehensive total cost function and introduce an innovative application of the Euler–Lagrange equation to minimize these costs. This approach, rarely applied in the context of optimal production planning, enables us to determine the time-dependent optimal production quantity.

Traditional scenario planning often focuses on probable outcomes, which can limit strategic vision and the preparation of strategies that go beyond the limits set by the six existing scenarios. However, NUUS encourages the consideration of improbable but possible high-impact scenarios, thus broadening the scope of strategic planning. We employ a qualitative methodology, integrating insights from the scenario planning and risk management literature. We further highlight the limitations of conventional approaches prioritizing the Maximax and Maximin criteria, proposing a seventh scenario incorporating a broader range of possibilities. The study demonstrates how NUUS can facilitate more robust strategic foresight by analysing historical case studies and theoretical frameworks. Mathematical reasoning is used to develop a framework for calculating the implications of these scenarios, emphasizing the importance of probabilistic thinking in risk assessment. We show organizations can benefit from adopting NUUS to navigate uncertainty and reduce risk. We also discuss the practical applications of NUUS, illustrating its potential to inform strategic decisions in complex environments. This study contributes to strategic management by integrating NUUS into decision-making frameworks. Although further empirical studies will be required to validate the effectiveness of NUUS in real-world applications, with the ultimate goal of equipping organizations with the tools necessary to thrive in an increasingly unpredictable world, the conceptualization of NUUS could serve as an impetus for this.

Understanding the asymmetric effects of macroeconomic factors on tourism demand is crucial for developing effective policies and strategies in the sector.

We employ linear and non-linear Autoregressive Distributed Lag (ARDL) models using quarterly data from 2003Q1 to 2023Q4. The results demonstrate that the asymmetric ARDL model outperforms its linear counterpart, revealing significant non-linear dynamics in tourism demand. We find that Thai outbound tourism responds more strongly to currency depreciations in destination countries than to appreciations. This asymmetry aligns with prospect theory, suggesting that tourists are more sensitive to potential cost savings than equivalent increases. The study also shows that increases in global economic uncertainty, as measured by the WUI, have a more pronounced negative impact on tourism flows than decreases in uncertainty. These findings have important implications for policymakers and tourism stakeholders in ASEAN countries.

To reduce the damages experienced by bushfires, predicting Australian bushfire ignition allows for an early warning system to give first responders and disaster managers prompt and accurate information.

Applying machine learning (ML) models enhances accuracy and reduces the computational time required to predict bushfire ignition. This study proposes a predictive model that can take meteorological and topographical data and determine the probability of Australian bushfire ignition and severity using historical fire detection gathered from the Black Summer Bushfire Disaster. The Black Summer Bushfire Disaster occurred between December 2019 and February 2020. The fires affected numerous towns throughout Victoria, New South Wales, and the Australian Capital Territory; hence, the varying topographical and meteorological conditions allow fire ignition and severity influences to be explored.
