Methods and systems for estimating process capacity

A system, comprising:

• a plurality of monitoring systems generating event logs, each event log indicating an event occurring at a given time at a given activity within a process;
• and
• a computing device communicatively coupled to the plurality of monitoring systems, the computing device comprising a processor a non-transitory memory storing instructions that when executed cause the processor to:
• load the event logs received from the plurality of monitoring systems;
• convert the event logs into a time series;
• Fourier transform the time series;
• measure shifts in spectral bandwidth in the Fourier-transformed time series;
• measure transition times between activities of the process from the event logs by identifying the shifts as the transition times;
• calculate a capacity of an activity of the process from the measured transition times;
• and
• generate an alert of the activity approaching or at a maximum capacity responsive to the capacity above a threshold.

A non-transitory computer-readable storage medium including an executable program stored thereon, the program configured to cause a processor to:

• load event logs received from monitoring systems communicatively coupled to the processor, each event log indicating an event occurring at a given time at a given activity within a process;
• convert the event logs into a time series;
• Fourier transform the time series;
• measure shifts in spectral bandwidth in the Fourier-transformed time series;
• measure transition times between activities of the process from the event logs identifying the shifts as the transition times;
• calculate, from the measured transition times, a capacity of an activity of the activities;
• and
• generate an alert indicating the activity approaching or at a maximum capacity of the activity responsive to the capacity above a threshold.
