There are usually inconsistencies in collaborative business processes established by the bottom-up modeling method, so the correctness analysis is an important means to ensure its correct implementation. Most of the existing methods focus on correctness detection, which makes the analysis process of correctness of collaborative business processes complicated and time consuming. The correctness repairing method can avoid the duplicate detection and adjustment existing in the correctness detection method. However, this method is less researched and cannot be effectively applied to the repair of collaborative business processes. To this end, a method of repairing the correctness of collaborative business processes is proposed based on the complete route. First, the behaviors of partial correct collaborative business processes are abstracted into complete simple routes under the consideration of active synchronization and asynchronous interaction, and merged them into a core. Then, the coordination mapping is used to map the core to repaired business processes, and the repaired collaborative business process is established by combining all the repaired business processes concurrently. The repaired collaborative business process conforms to the actual characteristics of collaborative business processes, and contains all complete traces in the pre-repair collaborative business process, and no hidden traces are also introduced, thereby avoiding validation. Finally, experiments are used to compare the proposed method with the existing methods. The results show that compared with the existing work, under the consideration of the actual characteristics of collaborative business processes, the proposed approach can more effectively repair collaborative business processes.
