石油化工工程模块化建设可有效提升施工效率,但不合理的成本管控会制约施工的顺利进行。借助解释结构模型(Interpretative Structural Modeling,ISM)—交叉影响矩阵相乘法(Matrices Impacts Croises-Multiplication Appliance Classement,MICMAC)，分析石油化工工程模块化建设的成本管控。总结装配式建筑与石油化工工程模块化建设的联系与差异,识别出成本管控因素;构建ISM模型揭示因素间4级3阶的递阶结构,发现根本影响因素;通过MICMAC分析将成本管控因素划分为依赖型、自治型及独立型,明确独立因素对成本管控的主导作用,并提出“标准体系强化—技术创新驱动—施工质量闭环”三位一体的成本管控策略。研究成果为石油化工工程模块化建设的成本优化提供了参考,可推动装配式建筑经验向石油化工工程的高效转化。

Modular construction in petrochemical engineering can effectively enhance construction efficiency; however, poor cost control may hinder smooth project progress. Utilizing the Interpretative Structural Modeling-Matrices Impacts Croises-Multiplication Appliance Classement(ISM-MICMAC), this study analyzes cost control within petrochemical engineering's modular construction. First, the study examines the relationship and differences between prefabricated buildings and petrochemical modular construction, identifying the key cost control factors; next, an ISM model is developed to unveil the four-level, three-tier hierarchical structure among factors, identifying core influencing elements. Then through MICMAC analysis, the cost control factors are categorized as dependent, autonomous or independent, clarifying the dominant role of independent factors in cost control. A trinity cost control strategy of “strengthening standard systems, driving technological innovation, and creating a closed loop of construction quality” is proposed. The research result provides a reference for the cost optimization of modular construction in petrochemical engineering, and can promote the efficient application of prefabricated building expertise to the sector.
