Abstract: It was difficult to realize effective function integration of multiple heterogeneous systems in discrete manufacturing process, which caused repeated switching of operators. To deal with this problem, a function interoperation method of multiple heterogeneous systems in discrete manufacturing process was presented. In this method, the interoperability of various system function interfaces in operation process were realized by encapsulating and calling the function interfaces of the systems, and the user-mapping mechanism was established to associate the authorities of various systems. On this basis, the interoperation processes were set up to help operators to complete the entire operation process. The formal description of the user-mapping mechanism and function interoperation process concerned above were introduced; the integration model of function interfaces in multiple systems, and the description frameworks of the user-mapping mechanism and interoperation processes were discussed. The realization mechanism of function interoperation process based on service Agent was put forward. Based on above methods, the prototype analysis was carried out to realize the integration of Manufacturing Execution System (MES), Distributed Numerical Control (DNC) system, quality detection and management system, and numerical control system. It proved that the proposed method was effective.
