Claim 5:
6. The detection method according to claim 1, wherein the following rule is followed by the first production system to make a determination in a case “Add New Route” and by the second production system to make a determination in a case “Add New Step” and in a case “Add New Route”:
determining whether contamination levels of steps in the new route match an order of contamination levels from low to high or not; and
determining whether a contamination flag input by each of steps other than a first step in the new route matches a contamination flag output by a corresponding previous process step or not; and
if so, determining that the process data passes the detection; or otherwise, determining that the process data does not pass the detection.
