针对生态工业决策的实践需要设计了“生态工业决策网络图”作为结构化表征生态工业决策问题的工具,探讨了基于这一工具的决策流程;然后以某天然气化工企业产业发展规划的制定过程为例,进行“生态工业决策网络图”应用的案例分析,说明了决策方案的提出,对应的生态工业决策网络图生成和修剪过程,通过直接定性、层次分析法综合以及逻辑推理3类过程完成了系统的决策。
A decision supportive tool “map of decision network for eco-industry”(MDNEI) was presented to structure and integrate the decision problem according to the needs of decision makers. The process of applying the tool was discussed. A MDNEI application based on the eco-industrial development plan of a natural gas chemical company was presented as a case study. The paper shows how the company decision-makers and the consultants brought forward the initial solutions and made choices, and corresponding MDNEI generating and shearing processes. The final solution was obtained based on three kinds of decision processes, directly qualitative judgment, synthetically quantitative judgment and structural inference.
