Abstract
A method, system, and computer program product, include identifying a plurality of pollution process sets and determining pollution sources based on pollution start times of target pollution processes with matched features in the plurality of pollution process sets within a time window.
Claims17
A computer-implemented method comprising:
- identifying a plurality of pollution process sets via a plurality of observation stations;
- determining pollution sources based on pollution start times of target pollution processes with matched features in the plurality of pollution process sets within a time window;
- analyzing a pollution migration path for the plurality of pollution process sets based on a plurality of groups of pollution concentration observations from the plurality of observation stations;
- separating emission inventory based on the identified pollution migration path;
- and
- performing a calculation with a newly separated and ordered emission inventory as a result of the prior separating and determining to generate a pollution source attribution as the pollution sources,
- wherein the pollution source attribution comprises which type of pollution attributes to a reason for the pollution start times of target pollution processes that results in the pollution migration path,
- wherein the target pollution processes with matched features are the pollution processes between which similarity is greater than a predetermined threshold, and
- wherein, for each of the plurality of pollution process sets, determining pollution processes which overlaps with the time window as, candidate pollution processes, the pollution process which overlaps with the time window includes the pollution process of which the pollution start time falls within the time window and the pollution end time falls outside the time window, then determining the target pollution processes having the matched features from the candidate pollution processes, where the target pollution processes each belongs to different pollution process set.
