Stakeholder decision-making method of carbon-hydrogen-oxygen symbiotic network

The invention discloses a carbon-hydrogen-oxygen symbiotic network stakeholder decision-making method, which comprises the following steps: firstly, based on a CHOSYNs multi-objective optimization method, respectively carrying out single-objective and multi-objective optimization on total annual cost, carbon dioxide annual emission and water annual emission to obtain a Utobang point and a lowest point; a stakeholder decision-making method is introduced, a feasible solution is calculated, weights are set for stakeholders with different viewpoints, priorities and standardized indexes are given according to the viewpoints, and a scheme with the highest satisfaction degree of the stakeholders is obtained by using a non-sponsoring degree index-removal rate. In order to solve the problems that the huge natural resource consumption and the waste discharge amount in EIPs in industrial parks do not reach the standard, the invention provides an EIPs system which collects, separates and converts substances containing C,
