生态工业园区的MINLP模型

A MINLP Model of Eco-Industrial Parks

生态工业园区的设计和管理需要建立在定量分析的基础上,目前仍然是一个薄弱环节. 本文提出了一个引入逻辑表达式的生态工业园区模型,可以通过对一个混合整数非线性规划(MINLP)问题进行求解来获得有价值的参考信息. 模型可以分为成员模型和连接模型两部分,成员模型作为积木,通过连接模型搭建成不同拓扑结构的生态工业园区方案. 开发的生态工业园区模型具有良好的扩展性、可修改性、可重用性,可以作为生态工业园区决策系统的核心模型. 以山东枣庄市南工业区为对象进行了案例分析. 模型用非线性优化软件LINGO求解.

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.
