“…Ansari [75] used SD to improve project planning by simulating change management policies for an Iranian construction project. Saad et al [76] used SD to simulate the ripple impact of design changes in healthcare construction projects, which can be used to allow proactive decision making for better design change management. Porwal et al [77] used SD to analyse the dynamic behaviour of system variables due to changes in the scope of works in order to minimize construction waste generation.…”

Researchers have increasingly used system dynamics (SD) as a modelling tool to understand the behaviour of systems with varying degrees of dynamism and complexity. SD has had a particularly significant impact in improving system representation, modelling, and abstraction of problems within the construction domain. However, there is a lack of comprehensive systematic literature review and content analysis on application of SD in construction engineering and management (CEM). In this study, a systematic literature review and content analysis were used to investigate 213 journal articles published from 1995 through 2021, presenting applications of SD in CEM research. This included analysis of SD research in terms of contributing authors and their affiliations; identifying the major CEM research areas and patterns of SD research within those areas; study of the current focus of SD research, future trends, and potential for future research in these CEM areas; investigating the SD modelling paradigm in terms of hybridization with other modelling techniques; and a review of issues and challenges of SD modelling. This study contributes to the body of knowledge by (1) addressing the lack of a comprehensive systematic review and content analysis in the application of SD in CEM research, (2) providing construction researchers and practitioners with the state-of-the-art in SD research and application within the construction industry, and (3) assessing the potential for SD hybridization with other modelling approaches and proposing areas of future research to improve SD modelling capabilities. This study found that (1) the concept of SD was mostly used in the research areas of decision making and policy analysis, performance, and rework and change, (2) the areas of scheduling and health and safety have acquired more interest in SD relative to previous trends, and (3) researchers have the lowest interest in the research area of bidding and procurement.

“…Rahman [25] also confirmed that design changes in Malaysia are the main reason for project schedule and cost overruns. Saad et al [27] put forward a system dynamics model to capture the factors that may lead to engineering and medical-related design changes in healthcare projects and investigated the impact of these design changes on project performance. Afsharghotli and Yitmen [28] used the artificial neural network (ANN) model to evaluate the quantitative measurement of the time and cost performance of petrochemical projects caused by the interactive design change.…”

In recent years, with the country’s vigorous promotion of green buildings and the increasingly complex and large-scale engineering projects, the design-construction consortium model can better meet the needs of the organization and implementation of large-scale green projects and become a realistic choice for enterprises in project implementation. Therefore, the formation of a good and stable cooperative relationship between consortium members is increasingly important in improving project revenue and quality. The issue of maintaining the stability of consortium relationships is an urgent problem to be solved at this stage. As such, a three-party evolutionary game model, based on evolutionary game theory, comprising the developer unit, design unit, and construction unit, is constructed here. Then, strategies for ensuring evolutionary stability under different design modalities are discussed. Finally, the influence of relevant parameters under changing design conditions on the stability of the design and construction consortium of green building projects is analyzed through numerical simulation. The research results show the following: (1) If the additional revenue distribution coefficient within the consortium members is closer to 0.5, the influence on the stability of the design and construction consortium will be smaller; in contrast, if the influence on the design and construction consortium is increased, the cooperative relationship within the consortium will be more unstable. (2) The presence of additional revenue can increase the stability of the design and construction consortium. An increase in the additional revenue will inhibit the instability of the consortium on the one hand and strengthen the stability of the consortium on the other but will also lead to the occurrence of opportunistic behavior. (3) The construction unit’s payment of a subsidy to the cooperative members can help promote the stability of the design and construction consortium to a certain extent and can also weaken the effects of other factors on the stability of the consortium, but there is a threshold value for the amount of said subsidy. (4) On the one hand, the cooperation members actively cooperate with each other to maximize the cooperation benefits of the design and construction consortium, while on the other hand, the construction unit actively promotes the implementation of the green building project, strictly monitors the implementation of the green design and green construction approach by the design and construction units in the early and implementation stages of the project, prevents the design changes caused by the final product failing to meet the green building standard, and actively solves design change problems in a manner that benefits the sustainable development of the green building, so that the cooperative relationship among the members of the consortium can develop steadily, which is beneficial to the green and ecological development of architectural design and construction.
