On Multi-objective Path Optimization Method for Hazardous Chemical Road Transportation Considering Emergency Support
To further improve the rationality of optimizing the road transportation path for hazardous chemicals,accident emergency support is introduced into the path optimization.It analyzes the impact of emergency support on path selection and its determination methods,and introduces the level of emergency support into the risk objective function as a compensation coefficient.Based on this,a multi-objective path selection model for hazardous chemical road transportation with the minimum transportation risk,shortest transportation time,and lowest transportation cost is constructed,and then using genetic simulated annealing(GSA)to solve it.The calculation example shows that the model can more reasonably and scientifically select the transportation path of hazardous chemicals,meeting the requirements of transportation enterprises for path safety and economic benefits.
