Abstract. Climate change is projected to increase flood risks in western Africa.

The covXtreme software provides functionality for estimation of marginal and conditional extreme value models, non-stationary with respect to covariates, environmental design contours. Generalised Pareto (GP) models peaks over threshold are estimated, using a piecewise-constant representation the variation GP scale parameters on (potentially multidimensional) covariate domain interest. one or more associated variates, given large single conditioning variate, is described extremes model Heffernan Tawn (2004), slope term which also assumed vary in piecewise constant manner covariates.

Evaluating the sustainability of smart cities is crucial for promoting sustainable development. Traditionally, this evaluation process has traditionally been carried out using Multi-Criteria Decision Analysis approach. However, approach relies upon a unified input dataset, which can lead to oversimplification, particularly in context sustainability. Further, does not take account how evolves over time. This paper introduces time-based assessment technique that combines with an established method assessing performance variability, recognized as Preference Ranking Organization Method Enrichment Evaluations. The resulting framework, called Enhanced Evaluations, was used evaluate and communities across G20 countries, based on aggregated data, individual dimensions, scenarios. results demonstrate effectiveness, relevance, applicability new approach, provides significant advance field city by facilitating multi-period evaluations enabling multi-perspective assessments.

Flat roofs can employ a range of technologies to improve sustainability, such as photovoltaic (PV) panels, green roofs, cool or combination these options. Yet, weighing the benefits, costs, and performance different roofing is complex, especially when stakeholders are involved. Decision analysis techniques, multi-criteria decision (MCDA), be used systematically evaluate diverse rooftop options assess trade-offs in quantitative way avoid biases. This study offers holistic comparison roof types, considering stakeholder preferences uncertainty using MCDA. Ten flat compared, including black, gravel, cool, extensive semi-intensive each with without PV installation, for nine objectives three hypothetical profiles.

For assumed an urban planner environmentalist, integrated installation best performing option; however, owner more concerned gravel ranks best. plays role results, particular, predicted outcome owner, which change top-ranking considerably.

Abstract Multi-line charts are commonly used in multi-criteria decision-making (MCDM) to represent multiple data series on the same graph. However, presence of conflicting criteria or divergent viewpoints introduces challenge accurately interpreting these charts, necessitating thoughtful design improve their comprehensibility. In this paper, we model multi-line as connected perfect matching bipartite graphs. We propose a metric called Coefficient Complexity (CoC) quantify complexity charts. order reduce visual minimize CoC by modeling it an integer linear optimization problem (reminiscent traveling salesman problem). demonstrate our techniques through real-life case studies, wherein serve visualization across various MCDM software tools. Additionally, with specific requirements have been optimized using approach, showcasing adaptability and efficacy technique. also formulate radar chart specialized form chart, adapt technique its The proposed important contributions field analytics, number methods use for aid. Consequently, enhancing comprehensibility can facilitate process help decision-makers gain insights.

The assessment of chemical alternatives for hazardous substances is an important prerequisite avoiding regrettable substitution, and several methods have been developed in the past to perform such a hazard alternatives. We investigate here whether GreenScreen, Cradle Cradle, multiple-criteria decision analysis (MCDA), Pollution Prevention Options Analysis System, U.S. EPA Safer Choice Standard Criteria, GHS column model 2020 from IFA use similar criteria evaluation as Article 57 European chemicals regulation, REACH, how suitable these are assessing per- polyfluoroalkyl substances. MCDA GreenScreen were analyzed detail using two different data sets. results assessments show that none investigated same described REACH. It was also not possible parametrize multi-attribute value theory (MAVT), commonly used method, align with REACH by relatively simple objective hierarchy has proposed previous publications. There therefore urgent need modified/new method can be future assess organic within Economic Area.
