The invention discloses a main and sub work order collaborative circulation method based on process model locking nodes, and relates to the technical field of work order circulation methods. The method comprises the following steps: firstly, constructing a main-sub work order classification
system, and establishing an independent process model containing key nodes and locking nodes for two types of work orders; then associating the main work order with the sub-work orders through a work
order management system, and establishing a node mapping relation table; implanting an identifier in a locking node of the sub-work order process model, and when the sub-work order process model is transferred to the node, sending a locking instruction to the main work order by the
system to suspend the main work order; the
task completion state of the sub-work order locking node is collected in real time, and after
verification is passed, the main work order releases limitation and continues to flow; and the process model can be dynamically adjusted, the exception is processed, and many-to-many association is supported. According to the method, the work order circulation efficiency is improved, the abnormal
response time is shortened, the association configuration efficiency is improved, the cross-factory collaborative
delay is reduced to 50ms, and the state
verification accuracy is high; the problems of work order association missing and low
collaboration efficiency are effectively solved, and the labor cost and the
delay risk are reduced.
