The project delivery mode is an extremely important link in the life cycle of water engineering. Many cases show that increases in the costs, construction period, and claims in the course of the implementation of water engineering are related to the decision of the project delivery mode in the early stages. Therefore, it is particularly important to choose a delivery mode that matches the water engineering. On the basis of identifying the key factors that affect the decision on the project delivery system and establishing a set of index systems, a comprehensive decision of engineering transaction is essentially considered to be a fuzzy multi-attribute group decision. In this study, intuitionistic fuzzy entropy was used to determine the weight of the influencing factors on the engineering transaction mode; then, intuitionistic fuzzy entropy was used to determine the weight of decision experts. Thus, a comprehensive scheme-ranking model based on an intuitionistic fuzzy hybrid average (IFHA) operator and intuitionistic fuzzy weighted average (IFWA) operator was established. Finally, a practical case analysis of a hydropower station further demonstrated the feasibility, objectivity, and scientific nature of the decision model.

This study aims to design incentives for organizations to improve the work engagement of construction project managers (CPMs) when they experience work-family conflict. Methods: Based on principal-agent theory, a multistage dynamic incentive model for CPMs' work engagement under the perspective of work-family conflict is constructed by integrating contract and reputation effect incentive mechanisms. Then MATLAB software was used to simulate the theoretical model for the arithmetic example. Finally, 182 valid questionnaires were tested for the conclusions of the model. Results: In the two stages of the incentive model, work resources significantly positively influence CPMs' work engagement, and work-family conflict harms CPMs' work engagement. Including a reputation mechanism has two effects on the first stage of the incentive model. First, reputation has an incentive effect on CPMs' work engagement. Second, it reduces the negative impact of work-family conflict on work engagement. The combination of contract-and reputation-based incentives will improve CPMs' work engagement. Conclusions: The results suggest that incentives targeted at increasing the work engagement of CPMs may be necessary.

Large-scale construction projects are characterized by the temporary cooperation of different parties with objectives, making it challenging to learn from failure under great time pressures. Learning from failure in such multiparties projects must overcome the fear of speaking out the “failure,” reflected by organizational psychology safety. This study aims to explore the impact of organizational psychology safety on the motivation of learning from failure under the mediating role of time pressure by a cross-sectional study. Data was collected by a questionnaire survey of 189 construction practitioners and analyzed by applying regression analysis. Results show that organizational psychology safety was negatively associated with time pressure and positively with the motivation of learning from failure. Time pressure was detrimental to the motivation of learning from failure, and it partially mediated the relationship between organizational psychology safety and motivation of learning from failure. Insights from the analysis could help the managers of organizations or projects to attach importance to the influence and role of learning from failure and could provide them with guides to implement lessons-learned systems.
