Modeling And Simulation Of Industrial Symbiosis In Virtual Industrial Park Based On Multi-Agent

In recent years,the development and construction of China's industrial parks have been very rapid and have sprung up.But most of the construction of industrial park is only investment promotion and capital introduction,and without fully considering the symbiotic relationship between enterprises or no reasonable planning in the process of building area,thus resulting in a lot of problems in the course of its development.this paper combines industry symbiosis,complementary chain and industrial spatial layout to explore the influence of industrial symbiosis on industrial parks.First,this paper expounds the research background,significance and domestic and foreign research results,The related theories of virtual industrial park,circular economy and multi-agent technology are summarized and summarized.Lay the foundation for the following model construction and simulation.Second,Through the research and analysis of domestic and foreign industrial symbiosis practices,According to the basic model of our economic development,relevant assumptions and reinforcing chains are carried out for virtual industrial parks.In the end,the virtual industrial park is constructed with steel processing,coal coking,aluminum processing and chemical plant as the core leading industries.At the same time,this paper introduces the main steps of SLP method for space layout setting and lays a theoretical foundation for further research.Again,By means of Multi-agent,the enterprise Agent,government Agent and natural environment Agent are established respectively,and the properties of agents and the conditions of the exchange of wastes are assumed.a waste exchange model of industrial symbiosis of virtual industrial park is constructed.Finally,the simulation process and output form of this paper are described.Finally,the simulation results show that the total output value of the park,the total profit of the park and the symbiotic trading volume of the park will continue to grow and stabilize over time.Wasting comprehensive utilization rate is higher in the park and thecomprehensive recycling waste not only reduced emissions of garden waste,reduce the pollution of the environment,but also save a large amount of raw materials,bring good economic benefits for the park;The addition of symbiotic enterprises has also increased many employment opportunities.In a word,the symbiosis between industries in the park has improved the economic,environmental and social benefits of the whole park.
