Methods, systems, and computer program products for controlling production systems. Methods include monitoring actual performance of a production system that includes a plurality of machines. The actual performance of the production system is compared to a planned level of performance of the production system. One or more short-term production constraints in the production system are identified in response to the actual performance being more than a threshold value away from the planned level of performance. A corrective action for the production system is determined to mitigate one or more of the short-term production constraints. The corrective action is applied to the production system.

Applying real-time control to a production system

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.

System and method for providing automatic resets

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.
