Title:
DIFFUSION STATE PREDICTION DEVICE, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2011/048998
Kind Code:
A1
Abstract:
Provided are a diffusion state prediction device, method, and program, wherein the diffusion calculation can be carried out precisely while reducing the processing time. The device is provided with a calculation grid determination unit (2) which determines a size of a calculation grid dividing a space in an area of focus; a boundary setting calculation unit (31) which reads out, from a building shape database(1), a building shape of a high-rise building which is a building higher than a length of one side of the calculation grid, sets the building shape to boundary conditions, and performs diffusion calculation of the area of focus; and a resistor calculation unit (32) which reads out, from the building shape database (1), one or a plurality of the said calculation grids surrounding a resistor group as low-rise calculation grids, the resistor group being a plurality of low-rise buildings which are buildings lower than the length of one side of the calculation grid, determines a resistance coefficient on the basis of space occupancy of the resistor group within the low-rise calculation grids, and performs diffusion calculation of the area of focus.
