Decision game of data sharing in supply chain enterprises considering data value over time

摘要

In the view of long-term cooperation, the total income function of long-term repeated game is established, and the change of equilibrium state and the space of improvement are discussed. When the data value changes with time, the total income function of different decision choices is further improved. Based on the trend analysis of income function, the influence of cumulative value on the stability of long-term cooperative relationship is discussed. Moreover, the game process and optimal strategy of upstream and downstream agents with data camouflage and sale behavior are analyzed, respectively, in the short and long term. The factors influencing the decision making, the interaction relation and the improvement suggestion of the optimal equilibrium are obtained.
