Research on stacking layout optimization of hazardous chemicals warehouse based on low carbon logistics
In order to ensure the safety of hazardous chemicals warehouses while effectively reducing the carbon emission and improving the economic efficiency,a multi-objective optimization model for the stacking layout of hazardous chemicals ware-house with the objective functions of minimum safety index,minimum material handling amount and minimum carbon emission cost was established.The model was solved by an improved hybrid particle swarm-tabu search algorithm.The algorithm added the multi-point mutation operation on the basis of the traditional particle swarm algorithm,and added a tabu search algorithm on the basis of the solution obtained by the particle swarm algorithm,so as to improve the ability of the algorithm to jump out of the local optimal solution.The results show that through using the established multi-objective optimization model and im-proved algorithm,all the hazard index,material handling amount,and carbon emission cost decrease,and the solution set qual-ity is high,thus reduce the material handling amount and carbon emission cost effectively while ensuring the safety of hazard-ous chemicals.The research results can provide reference for the influencing factors and numerical calculation of carbon emis-sion inside warehouses of hazardous chemicals enterprises,as well as defining the safety of hazardous chemicals warehouses.
