A modeling method for eco-industrial parks based on enterprise hubs

Abstract

The invention belongs to the field of the industrial ecological system analysis technology and particularly relates to an eco-industrial park modeling method. The modeling method includes the first step of putting forward a basic conception of enterprise hubs, the second step of utilizing the enterprise hub to describe four basic enterprise types forming an eco-industrial park, wherein the four basic enterprise types are energy producers, material producers, consumers and decomposers, the third step of utilizing the energy and material input and output relationship between enterprise hub interfaces to describe the symbiotic relationship between the enterprises, and the fourth step of utilizing enterprise hub models and the symbiotic relationship between the enterprises established based on a balance equation to form an eco-industrial park model. The method can be used for clearly and completely describing the organization structure and running behaviors of the eco-industrial park, and is high in universality and reusability and high in computational efficiency and capable of providing a quantified analysis method for design and planning of the eco-industrial park.

Description

technical field [0001] The invention belongs to the technical field of industrial ecological system analysis, and specifically relates to a modeling method of an ecological industrial park based on an enterprise hub. Background technique [0002] Driven by the demand for coordinated development of energy, economy, and environment, eco-industrial parks, as a typical representative of eco-industrial science, have become the mainstream development model of modern industrial organization forms. Eco-industrial parks are an important manifestation of industrial enterprises following the concept of sustainable development. It takes the circular economy as the core idea of ​​improving resource recycling and reducing pollutant emissions, and essentially provides energy, economy, and environment for coordinated development. an effective solution. With the gradual application and promotion of eco-industrial parks in industrial enterprises in various countries, this organizational form...

AI Technical Summary

Problems solved by technology

The main feature of these documents is that for the recycling of wastewater and waste heat in ecological industrial parks, a number of ecological industrial parks based on mathematical programming, such as mixed integer linear programming, mixed integer nonlinear programming, and fuzzy mathematical programming, have been proposed. Optimization model, the model includes optimization objectives and constraints. This type of model mainly solves the optimization problem of waste recycling in ecological industrial parks, and mainly focuses on the reuse of waste water and waste heat. It has not yet involved the comprehensive transformation and integration of different types of energy carriers. Secondary utilization, as well as the coupling relationship between material and energy, cannot give a comprehensive analysis of the symbiotic relationship in the eco-industrial park

In addition, according to the search of existing patents, there are no related patents related to research on the modeling method of eco-industrial parks

[0005] To sum up, the existing modeling methods of eco-industrial parks propose a series of models from the perspective of concept level and system optimization. At the system level, there is a lack of complete description and precise quantitative analysis of the organizational structure and operational behavior of eco-industrial parks
