Application in risk detection based on r- limited Voronoi diagram

Voronoi diagram is a very important and practical geometric construction in computation geometry. In this paper, r- limited Voronoi diagram was introduced into the spatial pattern of corporate staff´ safety awareness in emergent situation to describe the dynamic changes in the scope of swarm safety perception. Then, the virtual individual potential function of safety awareness emergency was put forward to enhance employees´ safety perception and risk detection capability. The simulation results show that with the passage of time, the radius and area of employees´ safety perception increase consistently under the guidance of potential function, and ultimately cover the entire region of space substantially.
