“…These tools have been designed to identify risks to operations based on an assessment of business assets, plausible risk, likely impacts and ownership of the driver of risk (Leonard, 1995). Risk registers are now widely used across sectors from construction (Kuchta & Ptaszyńska, 2017) to health (Mansfield et al, 2015). Quantitative and qualitative approaches to risk assessment are now commonly applied in environmental management, noting that uncertainty (in data and outcomes) is an inherent part of a multidisciplinary process (Hamel & Bryant, 2017).…”

1. Documented biodiversity loss has galvanised a global process to develop conceptual frameworks that link the social and ecological systems. This paper focusses on the development of the first marine natural capital asset and risk register as a foundational decision support tool to understand the risk to ecosystem service delivery in relation to policy or management interventions.2. We make use of existing marine data products to define the component parts of the asset status (extent, condition, spatial configuration) in line with a natural capital approach. We 'Pioneer' the application of this approach in North Devon, UK, an area defined by UK Government to test how marine natural capital can be effectively managed to deliver benefits to the environment, economy and people, and identify how best to share and scale up this learning.3. We demonstrate that the majority of asset-benefit relationships are at a medium to high risk of loss under current use and management. 4. Despite policy and management measures to reduce pressures on marine systems, activities linked to fishing, farming and the water industry continue to pose a medium to high risk to the asset-benefit relationships. A lack of accurate spatial fishing effort data greatly reduces opportunities for rational and targeted approaches to improve the condition status of marine natural capital assets.Marine protected areas as a single tool are insufficient to prevent further loss of biodiversity that underpins all asset-benefit relationships. 5. Synthesis and applications. Through development of the first marine natural capital asset and risk register we demonstrates a novel decision support tool to understand the risk to ecosystem service availability in relation to environmental policy or management interventions. The results highlight that current marine | 1099

“…Samantra et al proposed a comprehensive risk assessment method for urban construction projects based on the fuzzy set theory [10]. Kuchta and Ptaszyńska proposed a fuzzy risk registration method to identify risks in construction projects and evaluate their attributes [11] based on the existing risk assessment theory of urban rail transit project infrastructure. According to the translational velocity and angular velocity characteristics of the TBM, Yu et al established the dynamic performance evaluation model of the TBM by using the FAHP to determine the weight of the evaluation model [12].…”

There are many risk factors in EPB shield construction. The traditional fuzzy analytic hierarchy process (FAHP) method usually uses a linear analysis method to determine the risk level, but there are often some risk factors with prominent influence, which will reduce the accuracy of the evaluation results. In this paper, a new risk assessment model of Earth pressure balance (EPB) shield construction based on a nonlinear FAHP method is established by introducing nonlinear factors into the comprehensive calculation of the traditional FAHP. First, the new model establishes the framework of EPB shield construction risk analysis based on the work breakdown structure (WBS) and risk breakdown structure (RBS) methods. Then, it constructs an EPB shield construction risk index system by coupling the units of the WBS and RBS. The model constructs a fuzzy consistent judgment matrix, which replaces the 1∼9 scale. Finally, the nonlinear operator is introduced into the FAHP comprehensive calculation, considering the influence of some prominent risk factors, which improves the accuracy of the risk assessment. By applying the new model to the risk analysis of the EPB shield construction section of a tunnel project in Hangzhou, the effectiveness of the model is further verified.

Determining project characteristics and critical path by a new approach based on modified NWRT method and risk assessment under an interval type-2 fuzzy environment

et al. 2018

Considering the important role of risks in real-world projects and the ability of Interval Type-2 Fuzzy Sets (IT2FSs) to tackle uncertainty, this study introduces a new approach to consider risks and the correlation among risk factors by subjective judgment of experts on the probability and impact under IT2FSs. Furthermore, a new impact function used for considering the correlation among the risk factors is extended under an IT2F environment. Moreover, a new subtraction operator is introduced for the critical path analysis. The Node-Weighted Rooted Tree (NWRT) method is modi ed based on the proposed new operator to avoid producing negative number for characteristics of each activity. In addition, in order to deal with the uncertainty of the projects, NWRT method is developed under the IT2FSs. Finally, to illustrate the validity and capability of the proposed method, two examples derived from the literature are solved and compared.
