Performance evaluation risk management

Risk assessment starts with risk identification, a systematic use of available information to identify hazards (i.e., events or other conditions that have the potential to cause harm). Information can be from a variety of sources including stakeholders, historical data, information from the literature, and mathematical or scientific analyses. Risk analysis is then conducted to estimate the degree of risk associated with the identified hazards. This is estimated based on the likelihood of occurrence and resultant severity of harm. In some risk management tools, the ability to detect the hazard may also be considered. If the hazard is readily detectable, this may be considered a factor in the overall risk assessment. Risk evaluation determines if the risk is acceptable based on specified criteria. In a quality system environment, criteria would include impact on the overall performance of the quality system and the quality attributes of the finished product. The value of the risk assessment depends on how robust the data used in the assessment process is judged to be. The risk assessment process should take into account assumptions and reasonable sources of uncertainty. Risk assessment activities should be documented. 

Acknowledgment that mixtures may cause risks that are not fully covered by single compound evaluations does not automatically imply that mixture assessments should be performed for all potential mixture exposures. This depends on the problem at hand, the specific exposure situation, and the available information. If a regulator must make a decision about the remediation of 1 contaminated soil plot, and it is already known that one of the mixture components exceeds the remediation threshold, and this fact results in a need for remedial action itself, then a mixture assessment is redundant. Mixture assessment for contaminated soils (and other compartments and exposure routes) is useful if the known individual components do not exceed their respective thresholds, but if it is suspected that the overall mixture may still cause unacceptable adverse effects, and in case risk managers have a limited budget for a large number of contaminated sites, that is, when they have to prioritize the most hazardous sites to be remediated first, while other sites should possibly be subject to simple risk reduction measures. The situation is different for mixture emissions. Here, potential mixture effects should always be addressed because the aim was and is to establish an emission level that is lower than a certain (acceptable) effect level. 

Uncertainty analysis provides an evaluation of the key parameters that contribute to the uncertainty (e.g., variability and imprecision) involved in performing a risk assessment. Also known as probabilistic risk assessment, it provides information that enables decision makers to better understand the strengths, weaknesses, and assumptions inherent in the assessment and to evaluate the conclusions of the risk assessment accordingly. The result of the uncertainty analysis is a distribution of risks that a population may be potentially exposed to and thus, may be used by the risk manager to better understand the implication of the conclusions derived from the risk assessment and to support scientifically based and economically feasible hazardous waste management decisions. 

Application of bioassays for ecological assessments The evaluation of threats posed to ecological receptors or functions is probably the most significant reason for the application of biological test methods. There exist different approaches for using bioassays to perform risk assessments and to draw conclusions for risk management decisions. 

In environmental hazard assessment of chemicals, it is necessary to evaluate exposure and effects on humans or ecosystems, and then to perform an assessment. It consists of comparing the predicted environmental concentration (PEC) and the predicted no effect concentration (PNEC) and to make a judgement as to whether the chemical ent ng into environments is hazardous or not. Ultimately, risk management including regulation of chemicals is necessary if a potential hazard is predicted (see also chapter by Motschi). 

Culture—Promote a proactive risk reduction crrlture in day-to-day operations. Ask risk questions when making decisiorrs and performing operations. Incorporate risk consideratiorrs into basic management systems, such as recordkeeping, quality control, performance evaluation, and training. Think risk reduction. 

To assist in performing an appropriate risk assessment, the Research and Special Programs Administration (RSPA) has posted a Risk Management Self-Evaluation Framework on their website (http //hazmat.dot.gov). 

Research on performance evaluation index system of the large-exhibition project risk management... 

ABSTRACT The boom of large-scale complex projects over the world leads the risk management more and more imperative, which achieves good economic and social benefits. The risks of safety, quality, progress and investment of the large complex project construction were discussed, and a large complex project performance evaluation model of risk control was established, which can accomplish the fuzzy evaluation of risk control performance. This method makes the project managers to control the risk of project construction quantitatively and qualitatively. 

According to the above analysis of various risk factors, the importance of the relationship between a comprehensive consider index, based on the idea of multidimensional performance evaluation, combining with the characteristics of large conference and exhibition complex construction project management, safety, quality, progress, investment risk of key indicators summarized as follows, constructing evaluation index system were shown in Table 1.
