STRRAP system—A software for hazardous materials risk assessment and safe distances calculation

A novel fuzzy bi-objective vehicle routing and scheduling problem with time window constraint for a distribution system: A case study

“…According to what mentioned, it seems necessary to apply an appropriate tool to determine, classify and rank the high-level risks of the hazardous products transportation system. Therefore, various methods are proposed to calculate the risk value imposed on the hazardous products' transportation system [36,46,47]. In the present study, we proposed a novel framework to evaluate the hazardous product risk values as shown in Fig.…”

Bioaerosol Emissions: A Stochastic Approach

“…For fungi dispersion, the settling velocity is c a l c u l a t e d a s f u n c t i o n o f t h e s c e n a r i o characteristics (particle diameter ranges, Reynolds number, spreading coefficients, etc.) The proposed methodology is based on a simple representation of emitters and receptors (a squared grid) according to Godoy et al, 2007, 2010and Scenna & Santa Cruz, 2005. Every potential receptor is supposed to be placed in the geometrical centre of each grid square represented by the (X j ,Y k ) coordinates.…”

“…1 shows the general implemented computational strategy which can be concise in the flowchart and presents the three basic modules the computational package STRRAP (Godoy et al, 2007(Godoy et al, , 2010Scenna & Santa Cruz, 2005) has: 1. The pre-processor 2.…”

Multi-objective evolutionary emergency response optimization for major accidents

“…More precisely, these zones correspond to specific distances from the accident's source, with the type of protective action for the population in each zone predetermined. Several references are addressing the specification of emergency zones in case of a major nuclear accident [9][10][11][12][13][14][15][16], major accidents in chemical plants using hazardous materials [17][18][19][20] or transportation accidents involving hazardous materials [21][22][23]. Usually the extend of the zone is based on the intensity of the extreme phenomenon following the major accident.…”
