A MINLP Model of Eco-Industrial Parks
生态工业园区的MINLP模型

The design and management of eco-industrial park (EIP) should be conducted based on quantitativeanalysis, for which the principles and methods are needed to be developed. By means of deterministic mathematical programming, a model for EIP decision is developed with an object oriented method in this paper. Logical proposition expressions are introduced into the model, so that the decision in the course of EIP design and management can be formulated as a mixed integer nonlinear programming (MINLP) problem. The model consists of two kinds of blocks: member models and connection models. These blocks form a modular architecture, by which EIP scenarios with different topological structure are represented. It is easy to expand, modify, reuse the EIP model, and can be used as the kernel model in EIP decision making. A case study of a prototype EIP in Zaozhuang City, China is illustrated. Three mass and energy integrated scenarios are studied. The MINLP model is solved by LINGO software.
