Several studies have proposed methods for modelling and examining the outcomes of engineering change propagation. However, for reasons of practicality, designers need to be supported by simple tools which enable them to model and analyse dependencies among engineering parameters (EPs) in the early design phase. Utilising data gleaned from a prior completed project, this paper proposes a two-stage structural approach to achieve this objective. In the initial stage, interpretive structural modelling (ISM) is utilised to arrange EPs into a simple hierarchical form. In the following stage, cross-impact matrix multiplication (MICMAC) analysis is implemented to classify EPs in terms of their criticality. The results from modelling and analysis show that the proposed approach could be useful to designers opting to use engineering change propagation methods as well as to those who rely only on their experience and knowledge to assess the consequences of changes.

一种集成的 ISM-MICMAC 方法，用于在早期设计阶段对工程参数之间的相关性进行建模和分析

一些研究提出了建模和检查工程变更传播结果的方法。然而，出于实用性的考虑，设计师需要得到简单工具的支持，使他们能够在早期设计阶段对工程参数 (EP) 之间的相关性进行建模和分析。利用从先前完成的项目中收集的数据，本文提出了一种两阶段结构方法来实现这一目标。在初始阶段，解释性结构建模 (ISM) 用于将 EP 排列成简单的分层形式。在接下来的阶段，实施交叉影响矩阵乘法 (MICMAC) 分析以根据其重要性对 EP 进行分类。
