s441-4: and obtaining the pipeline evaluation result according to the abnormal coefficient evaluation result and the identification result.
Specifically, whether the conflict node information has an abnormal rule to adjust the conflict node is judged, and the pipeline is usually laid according to a certain laying rule when being laid, for example, a small pipeline avoids a large pipeline, a small pipeline has low manufacturing cost and is easy to avoid a large pipeline, and the like. When the conflict node is adjusted according to the abnormal rule, the reason for the conflict node is that construction is not carried out according to the conventional laying rule. And then, identifying the abnormal conflict node, namely identifying the reason of the abnormal conflict node, and acquiring a final identification result, wherein the final identification result can be acquired in a manual evaluation mode when the abnormal conflict node is identified. And acquiring an abnormal coefficient evaluation according to the identification result, wherein the abnormal coefficient evaluation is used for indicating the difficulty degree of processing the identification result, and the conflict node is difficult to process due to regularity, so that the abnormal rule adjustment conflict node needs to be independently evaluated.
