The paper presents the identification of hazardous locations in event a sudden release chemicals. In accident situations, risk is assessed on basis various methods and an action plan determined which aims to minimize risk. Accident situations PCB Dioxin was spilled large quantities were analyzed. methodologies World Health Organization, American EPA United Nations used paper. most important det...

it is difficult to prevent accidents in the transport of hazardous goods, so the development of strategies for managing crisis situations and the optimization of action plans are important. the crisis situation is a continuous event in time when its evolution is unpredictable because it depends on a whole of complex factors resulting from the environment of the crisis. decision making in crisis...

In this paper we present recent advances in developing and validating the safeguarded teleoperation approach to time-delayed remote driving. This approach shares control of the rover using a command fusion strategy: In benign situations, users remotely drive the rover; in hazardous situations, a safeguarding system running on-board the rover overwrites user commands to ensure vehicle safety. Th...

In today’s process systems, operators must consider an overwhelming amount of information which is passed to them via automated systems, and make decisions very quickly. Since the decision-making in a time-critical situation is extremely complicated, the use of automated systems to aid decision making is highly recommended. This paper proposes a hybrid Bayesian network (HBN) to support process ...

All Software Engineering (SE) processes include steps where several alternatives call for decisions. However, in many cases, the choice is intuitive and thereafter hazardous with unpredictable consequences. On the other side, the operational research domain has produced many methods that could be adequately used in these situations. Using these methods should facilitate the decision making acti...

Problems and Objectives. In Human-Robot Collaborative (HRC) applications, operators and robots work in a common space. Their close interactions increase the likelihood of direct physical contacts either due to the intrinsics of the operations (e.g., tools, motions, etc) or behavior of the operator (e.g., mistakes, misuses, instruction misunderstanding, etc). Unintended physical contacts may lea...

In advanced robotics, there is still a strong need for a fast reactive collision avoidance computable in realtime in order to prevent the robot from hazardous situations during motion. Most of these situations occur due to unforeseen events (e.g. collision objects entering the workspace accidently) or incorrect remote operation (e.g. scenery misinterpretation during teleoperation). Handling of ...

Any complex organization is confronted to hazardous or unpredictable events which are impossible to imagine and to anticipate due to the interactions and the nature of the components of the organization (person, machine, processes, etc.). Some risky situation may then impact the performance, the integrity and the stability of the organization. Actor involved into or in charge of this organizati...
