Cost-and-Benefit Evaluation of Windstorm Damage Mitigation Techniques in Florida

Der wachsende Bedarf an Wandlungsfähigkeit führt zu einer höheren Frequenz in der Umplanung von Montagesystemen und erfordert eine kontinuierliche Überprüfung und Anpassung des Automatisierungsgrades. Um auch die komplexen Umgebungsbedingungen abzubilden, sollen nicht-monetäre Faktoren in den Entscheidungsprozess eingebunden werden. Um die Entscheidung zu unterstützen, stellt dieser Beitrag ein Tool zur Identifizierung und Bewertung von Automatisierungsszenarien mittels einer Nutzwert-Aufwand-Analyse vor.   The increasing need for adaptability in assembly leads to a higher planning frequency of the system and requires continuous checks and adaptations of the appropriate level of automation. To account for the complex environmental conditions, non-monetary factors are included in the decision-making process. This paper presents a decision support tool to identify and evaluate automation scenarios by means of cost and benefit evaluation.

Operational Errors

Wind blades are major structural elements of wind turbines, but they are prone to damage like any other composite component. Blade damage can cause sudden structural failure and the associated costs to repair them are high. Therefore, it is important to identify the causation of damage to prevent defects during the manufacturing phase, transportation, and in operation. Generally, damage in wind blades can arise due to manufacturing defects, precipitation and debris, water ingress, variable loading due to wind, operational errors, lightning strikes, and fire. Early detection and mitigation techniques are required to avoid or reduce damage in costly wind turbine blades. This article provides an extensive review of viable solutions and approaches for damage mitigation in wind turbine blades.

Benefit Evaluation

This paper assesses the climate smart agricultural practices triggered by learning videos on integrated striga management, soil fertility and cost and benefit evaluation practices. Using household head interviews and focus group discussions, this study revealed that farmers have similar perceptions of climate change and related impacts in video-villages and in non-video-villages. However, farmers’ observation of climate change and related impacts are influenced by gender; men perceived more climate change and related impacts than women. In non-video villages, few respondents adopted crop rotation, intercropping, crop diversification, improved short-cycle seed varieties and zaï techniques as climate change adaptation strategies. Videos contribute more to the adoption of crop rotation, intercropping and fertilizer application for men than women. Videos on accounting (managing money) enable more women than men to enhance their cost-benefit evaluation practices for income improvement. During the interviews, women farmers in video-villages were eager to demonstrate their knowledge about cost and benefit evaluation. We also found that the yield of sorghum, millet and maize is high in video-villages and low in non-video-villages. Thus, using videos as extension tool is suitable for knowledge development and leads to the high adoption of climate-smart agricultural practices for food security.
