Workplace safety performance is computed using frequency rate (FR) and severity rate (SR). Only work time lost due to occupational incidents that need to be reported is counted. FR and SR are the 2 most important safety performance indicators that are applied universally; however, calculations differ from country to country. All injuries and time lost should be considered while calculating safe...

24 A cornerstone of effective institutional learning and accountability is the development, tracking, and analysis of informative performance measures. In a previous issue of Fire Management Today (“A New Look at Risk Management,” Winter 2011), a series of articles highlighted the importance of organizational safety and risk management and the challenges of balancing safety, efficiency, and eff...

introduction: safety culture is a set of beliefs, norms, incentives, social and technical roles and functions that make the core of the safety management system. the aim of this study was to examine factors affecting safety culture and its relationship to accident in the oil depots. methods: case-control study was conducted in 2016. 300 employees of 3 oil depot in tehran were selected that 150 ...

In this paper, we propose an algorithm for bounded safety verification for a class of hybrid systems described by metric transition systems. The algorithm combines exploration of the system trajectories and state space reduction using merging based on a bisimulation metric. The main novelty compared to an algorithm presented recently by Lerda et.al. lies in the introduction of a tuning paramete...

• New SPF functional form proposed that allows traffic volume to have different elasticities in ranges. Proposed for continuous relationship between predicted crash frequency and volume. models shown better fit observed data traditional other forms. Statistical of expected are referred as Safety Performance Functions (SPFs) the first edition American Association State Highway Transportation Off...

| Motivated by the fact that time delays in a practical Direct-Sequence Code-Division Multiple-Access system can never be perfectly estimated, an improved Minimum-Mean Squared-Error (MMSE) based receiver is proposed and analyzed. Via the simple assumption of a probability distribution for the delay estimation errors, the proposed receiver can achieve performance superior to that of the conventi...

This paper presents an application of a new stochastic programming method for vehicle side impact design. Nonlinear response surface models are employed as the 'real' models for the side impact related performance functions to conduct this study. The main goal is to enhance vehicle side impact crash performance while minimizing vehicle weight under various uncertainties. The new algorithm allev...
