During any extreme event, especially the evacuation in crowded places. The keys to saving lives are orderly and efficient evacuations. We have improved the traditional particle swarm optimization. It can simulate non-adaptive crowd behavior in the crowd facilities during the emergency evacuation. We introduce the concept of the leader (trained staff) and the parameter of influence, and analyzed the...
This article discusses the necessity, implementation methods and effectiveness of the performance management in the private enterprises. The main propositions are: analysis of the status and disadvantage of performance management in the private enterprises, performance management's objective is to achieve a win-win with the employees, to combine the performance management with the long-term strategic...
Most of the coalmine accidents are caused by people's unsafe behavior. Based on the basic theory and research methods of behavioral science, this paper analyzed human factors and rules affecting unsafe behavior. On this basis, it proposed the wholly integrated coalmine safety culture construction methods, with strengthening safety awareness, correcting unsafe behavior and training security practices...
The varieties of possible interaction between computational systems and physical environments is at the heart of a new modeling paradigm called cyber-physical systems. In order to model and control these interactions it necessary to present the fundamental properties of physical environments in a formalism compatible with the computational structures, usually in a formal logic or an algebraic calculus...
This paper applied the health risk assessment model recommended by the American Environmental Protection Bureau (EPA) , calculation the health risk and analysis the test index about As, Hg, Cr6+, Pb, Cd, F in Ya'an rural drinking water. The result indicates that the average concentration of the pollutants are respectively as follows: As: 0.004 mg/l, Hg: 0.001 mg/1, Cr6+: 0.005-0.015 mg/l, Pb: 0.01...
Vehicle following and its effects on traffic flow has been an active area of research. Human driving involves reaction times, delays and human errors that affect traffic flow adversely. One way to elliminate human errors and delays in vehicle following is to replace the human driver with a computer control system and sensors. The purpose of this paper is to come up with a control system for automatic...
