Oppositional NSGA-III-based optimization of multi-mode time–cost-safety risk-environmental impact for construction project
Despite many limitations, unravelling safety risks and environmental impacts in the tradeoff between construction time and cost has attracted significant attention. In an effort to address the shortcomings of existing trade-off models, this paper introduces a novel approach as a multi-mode time–cost-safety risk-environmental impact trade-off (MMTCSET). Unlike previous models, this paper utilizes a fuzzy function to express safety risk, considering both the probability and consequences of potential incidents. The assessment of environmental impact also includes an analysis of the emissions of gases, dust, and noise that arise from construction activities. Resources and multi-mode activities are considered by the model as the main constraints in construction projects. The oppositional non-dominated sorting genetic algorithm III is used in the development of the suggested MMTCSET model (ONSGA III). This algorithm offers a novel method for developing models using opposition-based learning for both generation jumping and initial population generation. An analysis of an existing case study project is conducted to illustrate the model's capabilities. The efficacy of the proposed approach is further highlighted by a comparison with results obtained from other trade-off models. Furthermore, trade-off plot and correlation analyses, along with sensitivity analysis, demonstrate the model's potential for application in scheduling decisions and explicit modeling in construction-related projects, making it a valuable tool for construction professionals.
