Due to the significant importance of petrochemical industry for Iran’s national economy and the environmental impacts such as wastewater, pollutant emissions, and hazardous wastes, the present study aimed to assess the construction and operation in two phases. Some relevant criteria were distinguished and weighted using Shannon’s entropy, as the objective weighting measures used to measure uncertainty, occurrence probability, severity, and vulnerability, and expert knowledge. The PROMETHEE technique was used due to the presence of large volumes of quantitative and qualitative data and its capability to evaluate the impacts. The steps included forming the evaluation matrix, determining the preference functions and function calculations. The relative desirability of each alternative was measured by calculating the net outranking flows. Finally, the activities were ranked. Based on the results, the main environmental negative impacts are the loss of vegetation cover and land use change, soil erosion and water and air pollution due to activities such as land cleanly shaven, establishment and operation of fuel tanks and drainage changes.

使用 Promethee 方法对石化工业进行环境影响评估；案例研究：伊朗阿拉克

由于石化工业对伊朗国民经济的重要性以及废水、污染物排放和危险废物等环境影响，本研究旨在分两个阶段评估建设和运营。使用香农熵对一些相关标准进行区分和加权，作为用于衡量不确定性、发生概率、严重性和脆弱性以及专家知识的客观加权度量。由于存在大量定量和定性数据及其评估影响的能力，因此使用了 PROMETHEE 技术。这些步骤包括形成评估矩阵、确定偏好函数和函数计算。每个备选方案的相对可取性是通过计算净排位流量来衡量的。最后，活动进行了排名。根据结果​​，主要的环境负面影响是植被覆盖的丧失和土地利用变化、水土流失以及由于土地清洁剃光、油箱的建立和运行以及排水系统变化等活动造成的水和空气污染。
