Risk assessment in work environments: modeling and simulation

Abstract

The paper proposes a characterization of risks and a service-oriented prototype to face risky situations in work environments, such as in industrial plants or building construction areas. A risk is the overture of emergencies that produce human and/or material damages. Therefore, it is particularly critical to identify and manage risks to avoid their evolution into emergencies. In this paper, we outline the technological features of a risk environment and propose a risk model and a service-based simulation prototype aimed to improve safety in work environments. We discuss engineering issues concerning risk modeling and management. Furthermore, we propose a risk management system solution and its related implemented prototype composed of services able to detect and also to prevent the occurrence of risk conditions

A web-based cooperative tool for risk management with adaptive security

“…To set an example, if the temperature in a given area is higher than the defined normal threshold, the temperature parameter is signaled as an event and might generate a risk. We assume that parameters are evaluated using a predefined approach, such as a threshold-based approach or a range-based approach, depending on the parameter at hand [7]. We model global risk and individual risks as shown in Fig.…”

“…E.g., water flooding that occurs close to electric plugs gives a higher risk level, and this level is not just the summation of the two individual risks. In the probabilistic risk model, we do not consider mutual-dependent risks but risks occurring one at a time [7].…”

“…We describe a Risk Management System (RMS) (see [7]) able to elaborate on events and risks and cooperating with an Access Control System (ACS) that is in charge of authorizations based on security rules. Such cooperation also considers the concepts of smart secure data in the Semantic Web and sets the basis for a framework that allows risk and security-related data to evolve and capture the aspects of security and risk management in dynamic environments.…”

“…We present a risk-adaptive access control model, assuming a preventive approach (risks are handled before they turn into crisis). Our purpose is to have a system able to ''reason'' about risks by employing a probabilistic approach about events arising in the environment using data collected from the environment (see [7]). …”

Access Control Privileges Management for Risk Areas

“…It is also possible to access them in time to prevent some of the damages caused by the crisis [1]. In particular, European projects such as OSIRIS [8] and projects in the US like IPAWS-OPEN [9], have made tools and standards available for interoperability of multi-domain sensor networks, and for processing and employing data (which currently emerge as themes of Big Data) provided by sensors for managing disasters and risks. There are common alert message standards that have been widely used and are available to public through online services namely, Common Alert Protocol (CAP) [10] which is an alert message standard.…”
