  • Patent number: 7212876
    Abstract: A system, method, and apparatus are provided for maintenance opportunity planning in a production line having a plurality of machines and buffers between machines on the production line, with the buffers processing production units between at least two of the machines. The system, method, and apparatus advantageously indicates maximum allowed downtime for a machine, through monitoring the status of the buffers to determine whether the flow of units through the buffers is favorable, monitoring the status of the plurality of machines, and determining which of the plurality of machines may be shut down for a particular period of time while substantially maintaining the favorable flow of units through the buffers. In this way, the inventive system and method saves time and resources by reducing production line downtime and unscheduled overtime.

  • Publication number: 20060288260
    Abstract: Disclosed herein are a system, method and apparatus for reporting, making alerts and predicting fault codes generated by machines in a line. Historical fault code data is received and filtered according to particular criteria to generate filtered fault code data. Classification of the filtered fault code data into physical groups and into logical groups is followed by sorting the groups to produce fault trend data. Processing the fault trend data with a plurality of analyzers generates output including reports, alerts, and predictions of future fault code occurrences.

  • Publication number: 20060143545
    Abstract: A method for determining whether to provide automatic reset instructions to a machine with reset capability with respect to a fault code event, the method comprising, in a database, collecting records comprising the identification of the machine, a fault code associated therewith and the duration of a fault associated with the fault code that the machine experienced within a time period, and performing a statistical analysis on the records to analyze whether executing an automatic reset on the machine with respect to the fault code will probabilistically rectify the fault and to generate resultant data.
