Dynamic incentive model of knowledge sharing in construction project team based on differential game

Abstract

The construction project team is a demanding, high-stress environment, yet wary participants can be extremely difficult in sharing their knowledge with others. This is a study that targets dynamic knowledge sharing in a construction project team, constructing a dynamic incentive model framework. It is done through the differential game theory, and the application of the Hamilton–Jacobi–Bellman equation is introduced to solve a Nash non-cooperative game and Leader-follower differential games. The results show that the optimal strategy of the Nash game is that agents do not share any knowledge and the principal does not give any incentives. However, the participants will share the cumulative amount of knowledge in the Leader-follower differential games, and the optimal profits of agents and principal are increased as time progressed, and the agents’ effort level of knowledge sharing eventually tending to stability.
