Abstract

A method of monitoring and recording real time data relating to the operation of a paper printing production machine includes the steps of: monitoring via a microprocessor time intervals between consecutive changes in status of the machine throughout the performance of the project; manually identifying to the microprocessor a particular status of the machine for each of the monitored time intervals; detecting a change in status of the machine by sensing a change in an operational condition of the machine, and, if no operational change in the machine is sensed, then detecting a change by the manual identification to the microprocessor of a particular status; manually identifying to the microprocessor a particular mechanical problem resulting in a breakdown of the machine; recording via the microprocessor the monitored time interval and the particular status identified; and calculating the sum of all time intervals monitored for each identified status. The monitored time intervals preferably include: time elapsed in setup; time elapsed awaiting supervisory review and inspection; down time elapsed due to breakdown; down time elapsed due to operator break; down time elapsed while idle; and time elapsed during running of the machine. The total time during performance of the project is thereby accounted for, and job efficiency is easily determined both during and after completion of the project.
