The profit margin of construction enterprises has been continuously declining over the past few years, and the competition for contracts among construction enterprises turns out to be increasingly fierce. Construction contracting enterprises should consider the profitability of the construction contracting enterprise and its ability to continuously obtain orders when setting cost budget targets for project management departments. Thus, a dual objective decision-making model is built in this study, minimizing overall construction costs and maximizing owner satisfaction to clarify the contracting conditions of the project management department and facilitate decision-making optimization of cost and owner satisfaction goals. Moreover, the actual effect of the proposed model method is verified through case calculations. As indicated by the results, under the premise of maximizing owner satisfaction, the model optimization cost is lower than the actual cost that has already occurred. Furthermore, it conforms to the goal of maximizing owner satisfaction while fulfilling the goal of minimizing engineering costs.
