The career and family interference Conflicts have existed from the past, but today it has become more widespread than before, and this research attempts to design a model of dynamic systems of double contradictions, the work-family Conflict, and the family-work dimensions for construction project professionals. In order to design a proposal based on the dynamic approach, Vensim software has been used. First, based on theoretical and theoretical foundations, the components that affect the Conflict between work-family and family-work Conflict were identified. Then, based on the equation between identified variables, a dynamic model of work-family Conflict and family-work Conflict was presented. The simulation results showed that construction project professionals experience a high level of work-family Conflict. It was also found that improvement in occupational flexibility and organizational support can have a positive impact on the satisfaction and performance of construction project professionals from the point of view of work and family. In addition, improving family support significantly improves their job satisfaction.
