Introduction:  Parking areas that are gathering places for tank trucks are potentially dangerous places. This study analyzes accident consequences of oil products carriers, to check and compare the hazard radius with recommended separation distances. Methods: This descriptive-analytical study was carried out in 5 stages, including: scenario selection, determination of the accidents source para...

here have been many methodologies proposed for the risk assessment in the chemical process industries (CPI). Among them, the most notable ones are quantitative risk analysis, probabilistic safety analysis, worst-case methodology for risk assessment and optimal risk analysis. A critical review of these methodologies is available (1). The key points of these methods are: Quantitative risk analysi...

Presently, there are few options with readily available software to perform a fully Bayesian analysis of time-to-event data wherein the hazard is estimated nonparametrically. One option is the piecewise exponential model, which requires an often unrealistic assumption that the hazard is piecewise constant over time. The primary aim of this paper is to construct a tractable nonparametric alterna...

This paper describes a technique for software safety analysis which has been developed with the specific aim of feeding into and guiding design development. The method draws on techniques from the chemical industries’ Hazard and Operability (HAZOP) analysis, combining this withwork on software failure classification to provide a structured approach to identifying the hazardous failure modes of ...

Risk assessment is an essential part in managing software development. Performing risk assessment during the early development phases enhances resource allocation decisions. In order to improve the software development process and the quality of software products, we need to be able to build risk analysis models based on data that can be collected early in the development process. These models ...
