A facility that includes machines, includes a camera generating facility operation data, which includes an image of any given space. A computer system comprises: a data obtaining module obtaining the facility operation data; a work identification module identifying work that is performed in the facility, based on the image included in the facility operation data; and an output module outputting time-series information indicating a flow of the work. The work identification module identifies an object included in the image; identifies the work based on information about the identified object; and generates work analysis data, which associates the identified work, a period in which the identified work has been performed, and machines that is related to the identified work with one another. The output module outputs the time-series information or statistical information by using the work analysis data.

A method for automatically associating a module to a corresponding inverter of a plurality of inverters which are adapted to generate measurements related to their operation, comprising: installing the module for generating measurements related to the operation of a corresponding inverter of the plurality of inverters; comparing, by processing means, the measurements generated by the module to the measurements generated by the plurality of inverters; and basing on the comparison, determining by the processing means which of the plurality of inverters is the corresponding inverter of the module.

A method for anomaly detection in a cutting machine with a spindle that is driven by an electric motor, wherein the method includes determining an electric power consumption of the motor during a working cycle of the machine, dividing the working cycle into time windows, determining, for each time window, whether the spindle was cutting and/or idling based on associated electric power values, determining median and expected deviation of electric power values for cutting and idling operation over the sequence of time windows, and determining an anomaly if electric power values during cutting or idling exceed a predetermined relationship to the corresponding median and expected deviation values.
