“…They investigated methods for mitigating or managing these risks, such as developing contingency plans and acquiring additional resources. Second, it was discovered in some studies (Ansari, 2021;Chen et al, 2021;Ford et al, 2002;Tran & Long, 2018) Szczesny & König (2015), should be mentioned as an approach to understanding construction scenarios with uncertainties.…”

Crises globais, como pandemias e guerras, evidenciam como os projetos de construção são afetados por eventos inesperados, normalmente ignorados pelas equipes de planejamento. Portanto, o objetivo deste estudo é revisar a literatura para entender como as incertezas são consideradas nos métodos de planejamento de obra e quais são as próximas etapas para enfrentar novas crises. Assim, os autores mapearam as variáveis tradicionais que são incluídas como incertezas nos métodos de planejamento, como tempo e custo do projeto, bem como as variáveis incomuns que não são normalmente incluídas como incertezas nos métodos, como questões de segurança e sustentabilidade. O estado da arte dos métodos de planejamento com incertezas envolveu uma leitura minuciosa de 103 artigos de periódicos encontrados por meio de uma revisão sistemática adaptada da literatura, que incluiu, além dos processos tradicionais, um estudo cienciométrico e uma análise de bola de neve. Como resultado, descobriu-se que as principais incertezas consideradas estão relacionadas a tempo, custo e recursos. Além disso, foi possível observar que não existe uma única técnica consolidada para incorporar incertezas nos métodos de planejamento, mas sim uma combinação de diferentes técnicas, desde as mais tradicionais com análise analítica até as mais contemporâneas com algoritmos de inteligência artificial.

“…is model combines variable neighborhood search (VNS) with an event-driven simulation framework. e simulation experiment adopted a dual-objective optimization model to minimize the project completion time and maximize a new agent robustness function at the same time [1]. e sustainability calculation algorithm is indeed very effective in optimizing the project completion time, but generally, such research will ignore the control of project quality and cost, which will lead to the two extremes of the project, either the quality is not good enough, or the cost is high.…”

BIM (Building Information Modeling) is to create models based on various related information in construction projects and use simulation virtual technology to model actual building information. It is not only the integration of digital information but also the application of digital information in engineering construction. Digital models can be used to plan and simulate the whole process of construction projects scientifically and accurately. In the process of project construction, wireless network communication technology can provide a good basis for collaboration, which is essential for the control of project progress, task scheduling, and systematic communication between all parties. This article introduces the LTE wireless network communication technology and network coverage plan, summarizes the cost and schedule control principles of construction projects, analyzes the factors that affect the construction schedule in subway construction, and introduces the application of BIM technology in subway construction schedule control. Taking the construction of Section XX of Line 1 of City A as an example, a simulation experiment was carried out, and the optimization effect was evaluated with SPI and CPI indicators. The final experimental results show that it is meaningful to use the BIM model algorithm to optimize the subway project. In the simulation experiment, the corresponding construction period saving rate after completion of the project is 6.94%.
