The working principle of the SPLIT function method is as follows: traversing to find REGEX, and adding the middle part from the front of REGEX to the last position to LIST; if not, returning to the one-dimensional array; whether to add the rest content to LIST, whether to remove empty character strings in LIST; from LIST, the array is returned.
The Limit value for the SPLIT function includes the following:
when limit <0, then e.g. limit= -1;
when limit=0, then the default is 0;
when limit >0, then e.g. limit=3;

delivery route number n=3;
strs0= "parts factory";
strs1= "sheet metal works";
strs2= "surface treatment plant";
strs3= "assembly plant";
step 2: when the yield to be delivered meets the conditions, a yield delivery control table is generated by a process control triggering component through the identification confirmation of a craftsman to form a yield delivery circulation database, a workflow is triggered by the process control component, the workflow is matched, identified and bound with a delivery installation route, and the process of delivering the yield to be delivered is ensured to circulate according to the process route obtained by analysis in the step 1.
Specifically, setting X as yield to be delivered, setting A as yield number collection generated by all part factories, and setting B as yield approval single number collection agreed by all decision makers.

Step 3.3: and (3) pasting the red label for yield on the surface of the part, delivering the yield to a part use unit for storage along with delivery, and forwarding the new red label for yield by the part use unit and delivering the new red label to a downstream unit after pasting until the red label is delivered to an assembly plant, so that the uniqueness and the special property of the yield can be conveniently and effectively displayed for users.
Step 4: the circulation record acquisition component is used for scanning the yield bar code by production scheduling personnel, identifying and opening a yield delivery control table through the unique identification of the yield number, and confirming whether the yield to be delivered is circulated or not through a part delivery installation route acquired in a planned bill of materials, if the circulation is not needed, the circulation record acquisition component is not executed; if the yield is required to be transferred, recording yield transfer information in a yield transfer control table through a transfer record acquisition component, and transferring the yield transfer information to a yield transfer database; after confirmation of yield transfer information submitting inspectors, the downstream unit dispatcher continues to scan and fill in yield transfer information until all intermediate unit transfer is completed and all yield transfer information is recorded and transferred to a yield transfer database.
Specifically, by scheduling a part delivery installation route acquired from a bill of materials, whether a yield to be delivered is circulated or not is confirmed, and specifically, the number of intermediate units of the delivery route is set as Z:
when z=0, the no-flow is needed, and the function of the flow record acquisition component is not executed;
when Z is not equal to 0, the circulation is needed, a circulation record acquisition component is executed, and the to-be-delivered yield circulation is transferred to a downstream unit. In this embodiment, according to the delivery installation route, the middle unit has a sheet metal factory and a surface treatment factory, that is, z=2, and the step-down product circulation information is recorded through the component, and the specific circulation flow is as follows: the part factory delivery unit dispatcher designates a sheet metal factory dispatcher, a yield control bar code is handed over, the intermediate unit sheet metal factory dispatcher scans the yield bar code, reads yield information and fills in updated yield delivery process information, the yield information comprises a drawing number and a special part number, a sheet metal factory inspector confirms when the yield is transferred out, after confirmation of the inspector, the intermediate unit sheet metal factory dispatcher scans the yield bar code for the next intermediate unit surface treatment factory dispatcher, reads the yield information and fills in updated yield delivery process information, the yield information comprises a drawing number and a special part number, the surface treatment factory inspector confirms when the yield is transferred out, and the intermediate unit sheet metal factory and the surface treatment factory transfer are completed and record all yield transfer information and transfer the yield transfer information to a yield delivery transfer database.
