Abstract
A process monitor system collects process execution status data such as work-in-process information from multiple manufacturing execution systems controlling multiple fabrication lines of factories of a firm. The process monitor system converts and encapsulates the process execution status data with a common standard formatting. The process execution status data is then published to subscribers of specific subjects of the process execution status data. The converted and encapsulated process execution status data is logged to a message ledger to certify publication and receipt by subscribers. A periodic diagnostic messaging or heartbeat is transmitted between elements processing and publishing the process execution status data to provide failure recovery. The elements processing and publishing the process execution status data are connected as a distributed queue of parallel process and have a designated scheduler to provide a balancing of loading.
