Abstract: The technical complexity requires the operator to reserve the supplier's repair capacity during longer lead time.However,the operator must face to the challenge of uncertainty of repair demand in short period,and cope with the competition from other operator using similar equipment,which lead to a mismatch between actual repair demand and reserved capacity.Considering the new opportunity for sharing the supplier's repair capacity reserved among cooperative operators in industrial internet platform,the repair capacity reservation was studied by taking the biform game theory as the modeling framework,and a two-stage decision method was executed.In cooperation stage,the optimal allocation of multiple operators' execution abilities was solved;in competitive stage,the independent competitive decision method of operators was constructed to prove the existence and uniqueness of Nash-equilibrium solution for reservation capacity.Compared with optimal solutions of reservation and allocation of repair capacity,the equilibrium solutions were investigated in three scenarios with the excess,insufficient and exact reservation,then reason of the gap was presented.The theoretical analysis and simulative results confirmed that the profit of operator could achieve the first-best level and that reserved capacity decisions in biform game and centralized optimization all outperform that of the operator by oneself.As a result,the proposed modeling of biform game could provide an effective method to solve this inherent difficulty and achieve a win-win situation in the service platform.
