presence of risks and uncertainties inherent in project development and implementation playssignificant role in poor project performance. thus, there is a considerable need to have an effective riskanalysis approach in order to assess the impact of different risks on the project objectives. a powerful riskanalysis approach may consider dynamic nature of risks throughout the life cycle of the pr...

Introduction: Safety and health risk assessment in industries is associated with uncertainties due to the variables affecting it. Therefore, in this research, optimizing safety and health risk assessment was investigated in construction sites by combining a multi-criteria decision-making technique (TOPSIS) and a fuzzy system. In the present study, to answer this question, a new method was used ...

Numerous types of uncertainty arise when using formal models in the analysis of risks. Uncertainty is best seen as a relation, allowing a clear separation of the object, source and 'owner' of the uncertainty, and we argue that all expressions of uncertainty are constructed from judgements based on possibly inadequate assumptions, and are therefore contingent. We consider a five-level structure ...

We present an update to an electric shock job exposure matrix (JEM) that assigned ordinal electric shocks exposure for 501 occupational titles based on electric shocks and electrocutions from two available data sources and expert judgment. Using formal expert elicitation and starting with data on electric injury, we arrive at a consensus-based JEM. In our new JEM, we quantify exposures by addin...

How an organization handles uncertainties stemming from its own production processes and from its environment, is a central characteristic of its functioning. Many organizations, foremost those which have to handle substantial health and safety risks, aim at minimizing uncertainties. This is in contrast with newer organization theory which argues for enabling local competence for coping with un...

Model Predictive Control (MPC) of combined sewer systems can reduce environmental degradation caused by uncontrolled overflows. However, practical uncertainties are often neglected when assessing the potential MPC strategies. This paper aims to understand risks associated with using a non-perfect internal MPC-model, real precipitation forecast, and realistic dynamic system capacity fluctuations...

Dr. de Melo-Martin examines the risks, uncertainties and public policies surrounding in vitro fertilization and women's health issues.
