Abstract:
... In recent years, a need for product traceability in the cold supply chain has emerged. The purpose of this study was to identify and map out different kinds of identification technologies and techniques used for cold supply chain traceability. This was done by looking into what traceability solutions are available right now through literature review. The results from this review were then further ...

Abstract:
... Robust environmental decision support tools are critical to maximise the ecological benefit of management decisions. However the models that underpin these rarely undergo rigorous evaluation. Here, we evaluated components of a scenario-based habitat suitability model, the Murray Flow Assessment Tool, by correlating model outputs against fish monitoring data collected since its development. Overall ...
... Rail fasteners are critical components in high-speed railway. Therefore, they are inspected periodically to ensure the safety of high-speed trains. Manual inspection and two-dimensional visual inspection are the commonly used methods. However, both of them have drawbacks. In this paper, a rigorous high-speed railway fastener inspection approach from structured light sensors is proposed to detect d ...

Abstract:
... This paper examines efficiencies achieved by optimal scheduling of power generation equipment and electrical loads in a hybrid smart micro-grid under conditions where load activity may be delayed or advanced with negligible impact to system performance. We model military expeditionary energy systems to analyze the performance of existing unmanaged components and estimate potential savings obtained ...

Abstract:
... Use of robots in product disassembly is growing in popularity, mainly due to ever-increasing labour costs in both developed and developing countries. However, currently there are no approaches for assessing the trade-offs between environmental benefits, technological feasibility and economic viability of robotic disassembly. The work presented in this paper aims to justify the future application o ...

Abstract:
... Reports of the Intergovernmental Panel on Climate Change (IPCC) employ an evolving framework of calibrated language for assessing and communicating degrees of certainty in findings. A persistent challenge for this framework has been ambiguity in the relationship between multiple degree-of-certainty metrics. We aim to clarify the relationship between the likelihood and confidence metrics used in th ...
... According to the classic results of Galton and Condorcet, as well as in modern decision-making models, accuracy in groups increases with group size. However, these studies do not consider the naturally occurring situation in which individuals dynamically re-evaluate their decision with a possible change of opinion. The dynamics of re-evaluation in groups are very different to individual re-evaluat ...

Abstract:
... Remanufacturing as an end-of-life disposal option poses challenges due to product and process complexities, customer requirements, and uncertainties associated with product take back and the remanufactured products’ market-base. To address these challenges, this study presents a decision support system based on a bi-level fuzzy computing approach that incorporates qualitative and quantitative prod ...
... Since 2007, a range of new modeling approaches and tools have been developed for sustainability impact assessment (SIA), but a lack of universal acceptance of SIA tools in applied policy making is observed. The current article gives an overview of experiences from several European and international projects, critically reviews the selected SIA tools and then discusses a number of reasons for the o ...

Abstract:
... Any ecosystem based fisheries management system is necessarily faced with the problem of multiple objectives that trade-off against one another. Typically, objectives such as the maximization of yield, employment or profit or minimizing environmental impacts will be optimized in different parts of the decision space, which is formed of the fishing mortality rates that can be applied to the various ...
... Among the activities managed by an organization, the maintenance of the resources it uses considerably affects sustainable performance. In this paper, we propose research on decision support for controlling sustainable performance induced by maintenance processes based on the core principles of decision systems. We discuss their application in maintenance, and underline the weaknesses of current p ...

Abstract:
... More recently, firms embark on many initiatives for sustainability. Closed-loop supply chain (CLSC) is an initiative that extends the scope of value creation through product reconstruction activity. The process of product reconstruction includes acquisition of the used products from customers, recovering their residual value, and remarketing them. The aim of this research is to propose a conceptua ...

Abstract:
... A majority of fisheries worldwide lack effective management because of poor quality data and limited resources. Data-limited stock assessments are increasingly used where model-based, data-rich approaches are not possible. However, their widespread use is constrained by several important limitations, especially the inability to estimate biomass or maximum sustainable yield (MSY)-based reference po ...

Abstract:
... Ensembles of decision trees are a useful tool for obtaining flexible estimates of regression functions. Examples of these methods include gradient‐boosted decision trees, random forests and Bayesian classification and regression trees. Two potential shortcomings of tree ensembles are their lack of smoothness and their vulnerability to the curse of dimensionality. We show that these issues can be o ...

Abstract:
... Hydraulic structures have a direct, strong and long-lasting impact on the economy and society in general. Providing the proper structural solution implies finding a balance between economic, environmental and social requirements while decisions taken are associated with serious and irreversible consequences. Optimization techniques play a key role in finding the right solution. In this paper, for ...

Abstract:
... The global dissemination of operational systems for flood forecasting, early warning and risk management is much more heterogeneous than comparable forecasting services found in the meteorological community. This results primarily from the need for local ‘on-the-ground’ knowledge, such as addressing regional hydrological phenomena or the impact of local water resources management, and the challeng ...

Abstract:
... Accidental river pollution can cause damage to the environment, put at risk the health of people that use the water for domestic purposes, and, not lastly, compromise dependent economic activities (e.g., agriculture). The reduction of the concentration of pollutant on any river following an accidental pollution can be achieved using dilution, by opening for certain duration the bottom gates of the ...

... Conservation practitioners face complex challenges due to resource limitations, biological and socioeconomic trade‐offs, involvement of diverse interest groups, and data deficiencies. To help address these challenges, there are a growing number of frameworks for systematic decision making. Three prominent frameworks are structured decision making, systematic conservation prioritization, and system ...
