Optimization of Multiple Products Transportation Under the Background of Industrial Symbiosis Network

Abstract

Starting from the hotspots of solid waste recycling and reuse, and considering the characteristics of waste transportation in eco-industrial symbiotic network, this paper takes the transportation and distribution process of waste and by-product recycling and reuse in upstream and downstream enterprise clusters as the research object. Different from the traditional transportation research which a single goal-oriented and multi-product independent, Considering model the economic cost performance and environmental performance, as well as the "transport price correlation" between various wastes, this paper constructs a multi-objective transport planning model of Interacted multi-product. Finally, on the basis of the multi-product and multi-objective model, the paper refers to the related method theory of the second generation fast non-dominated sorting genetic algorithm (NSGA-II) which based on the elite selection strategy. By carrying out calculation and result analysis on the basis of algorithm implementation, the paper verifies the effectiveness of the model and algorithm.
