- Analyzing and Classifying Risks: A Case-Study in the Furniture IndustryPublication . Leão, Celina P.; Rodrigues, Matilde; Brito, IreneIn this work we propose a methodology which permits the risk analysis and classification of occupational accidents in industrial settings. Data used in this study corresponds to accidents that occurred in the furniture industry in Portugal in 2010. A loss random variable is constructed in order to model the number of lost days implied by different contact modes of injuries in industry. The corresponding risk measures, such as Value-at-Risk, expected loss, loss variance and exceedance probabilities are determined in order to analyze and classify the contact modes according to their risk level, allowing the identification of the most problematic and the less problematic accident category in this industry. Contact with cutting, sharp, rough material was the most problematic whereas contact with electrical current, temperature, hazardous substance was the one with lower risk level.
- Risk analysis and risk measures applied to the furniture industryPublication . Brito, Irene; Leão, Celine P.; Rodrigues, MatildeIn this work we show how concepts and methods from actuarial risk theory can be applied to risk analysis in industry. Risk analysis consists in identifying, quantifying and classifying or ordering risks. In the proposed methodology, the risks identified in industrial setting, are modeled by loss random variables. The loss random variables are used to calculate the expected loss, the loss variance and exceedance probabilities permitting risk quantification. In order to classify and order risks, besides measures of uncertainty, risk measures, such as Value-at Risk and Tail-Value-at-Risk (or Expected Shortfall) are determined and, together with risk quantification, the risk levels are analysed. To exemplify this methodology, a case study for risk analysis and classification of occupational accidents in the furniture industry was carried out.
