An Integrated Quantitative Assessment Model For Usability Engineering
Many different quantitative assessment models have been proposed to measure and report the usability of a general software product for various business and design purposes. However, there are several problems coupled with existing models that consequently bias and affect the process and results of the usability assessment. Moreover, they do not aid their usage by analysts who are not experience...
متن کاملA quantitative risk assessment model for Salmonella and whole chickens.
Existing data and predictive models were used to define the input settings of a previously developed but modified quantitative risk assessment model (QRAM) for Salmonella and whole chickens. The QRAM was constructed in an Excel spreadsheet and was simulated using @Risk. The retail-to-table pathway was modeled as a series of unit operations and associated pathogen events that included initial co...
متن کاملCrystalline silica exposure and lung cancer mortality in diatomaceous earth industry workers: a quantitative risk assessment.
OBJECTIVE To use various exposure-response models to estimate the risk of mortality from lung cancer due to occupational exposure to respirable crystalline silica dust. METHODS Data from a cohort mortality study of 2342 white male California diatomaceous earth mining and processing workers exposed to crystalline silica dust (mainly cristobalite) were reanalyzed with Poisson regression and Cox...
متن کاملQualitative and quantitative risk assessment
Risk assessment and HACCP are related, but fundamentally dierent processes. Four major elements of risk assessment are commonly described (hazard identi®cation; exposure assessment; dose-response assessment or hazard characterization; and risk characterization). Some similarities exist between the inputs for the ®rst elements of risk assessment (hazard identi®cation) and HACCP (hazard analysis...
متن کاملSemi-quantitative risk assessment of health exposure to hazardous chemical agents in a petrochemical plant
Background: Chemical contaminants present in the work environments include gases, vapors, and solid and liquid suspended particles. The number of factories producing chemicals has increased significantly. Each year, new products are introduced into the market. Consequently, the number of employees at risk of exposure to these materials is increased. Hazardous chemicals are used in the petrochem...
