ABSTRACT
Taking the domestic waste reverse logistics network in Hefei as the research object, considering
the multi frequency recycling and vehicle sharing scheduling strategy, a reverse logistics network
optimization scheme based on the operation cost of the reverse logistics network is proposed. Firstly,
a reverse logistics recycling operation cost model is constructed, which includes the construction
cost of reverse logistics infrastructure, equipment maintenance cost, the sum of the transportation
cost of municipal solid waste and the treatment cost of non-recyclable waste at all levels,
and a product maximization revenue model of the recycling center is established. Secondly, according
to the characteristics of the model, a k-means spatio-temporal clustering algorithm considering
the geographical location of waste transfer stations, recycling frequency and recycling time window
is designed, and then an improved GA-PSO hybrid algorithm is proposed. The effectiveness of the model
and algorithm is verified by comparing with HGA, GA-TS and HACO algorithms. Finally, according
to the actual data of Hefei domestic waste reverse logistics network, the optimization research was
carried out, and the recycling frequency and vehicle scheduling of transfer stations in different locations
were analyzed. The results show that the model and algorithm proposed in this paper can carry out
the optimal selection of recycling cost, resource sharing of recycling vehicles and reasonable vehicle
routing optimization scheduling, and the operation cost of reverse logistics network is reduced by 8%
compared with the previous one; As the transportation distance is reduced, the transportation cost
is greatly reduced, and the treatment efficiency of municipal solid waste is improved.
