Some Worker Tasks may need to update, because the risk results that compute in the previous 3D environment may not be valid anymore. Changes on the manufactured product (MBOM) may also have an impact. Finally, changes at the Process Planning level may also invalidate some Worker Tasks, for example if the operation flow modifies.
At the start, the system performs several verifications to warn you that the risk assessment may not be accurate, because action done outside of the app. The hatched icon aspect is the indication that the workers context may not be accurate, thus the risk identification is not valid. The first verification is on the worker task content. The system verifies that any object referred by the Phrase exists in the PPR structure. If an object is missing, then the Phrase may not be valid anymore. In this case, the corresponding Worker Task is flagged out-of-sync. Moreover, if an object is missing, it frees up some space, thus a previously generated posture may optimize for the surrounding Worker Tasks. Consequently, all the Workers task of the entire system (what operation the worker does) are flagged out-of-sync. This also occurs if any resource used in the Worker Task modifies. The second verification is at the MBOM level. In this implementation, it cannot identify the modifications cause. If the modification is a shape, it can create/reduce the available space, or change the grasp strategy. If the part’s weight changes, it affects the posturing strategy. Those two types of changes may affect all the Worker tasks where this part is present. Thus, if any of the MBOM parts modifies, the system retrieves the operation that implements (adds) it to the build-up. This also flags out-of-sync all the Worker Tasks of this operation and the following operations, process-wide (not only in the system that the operation belongs to). There are limitations:
