Dealing with concept drifts in process mining.

Dealing with concept drifts in process mining. Bose RP, van der Aalst WM, Zliobaite I, Pechenizkiy M. Although most business processes change over time, contemporary process mining techniques tend to analyze these processes as if they are in a steady state. Processes may change suddenly or gradually. The drift may be periodic (e.g., because of seasonal influences) or one-of-a-kind (e.g., the ...

Assuming a day and night shift are both working in the same drift heading, up to 7m can be advanced in a 24-hr period. Based on this rate, or whichever rate of advance is planned for, the time it will take can be determined . For example, a drift is planned to be 30m long and requires 30m of development. A drift round is 3m in length and a round can be taken each shift. Therefore, to complete ...
