摘要： 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.

摘要： A costing process that takes advantage of real-time information about plant floor activities and provides a more accurate and timely financial feedback about the process efficiencies in response to new changes in the process operation. The costing process includes identifying stations that consume resources, consume activities and supply activities. The costing process also identifies a plurality of resources that are provided to one or more of the stations. The costing process also includes identifying resources from the plurality of resources that are used as needed and resources that are supplied in advance of being used. The costing process allocates costs for each resource to each station that the resource supplies, including calculating a cost rate, calculating a cost of used capacity and calculating a cost of unused capacity. The costing process then determines the cost that each station and product uses based on the allocations.

摘要： A method for testing the safety automation logic used in a manufacturing cell includes recording control signals of a safety-related component such as an E-Stop, light curtain, gate lock, or a safety mat using a host machine, and then disconnecting the component from the host machine. The recorded test signals are transmitted to an automation controller in accordance with a test scenario from a test scenario generator module (TSGM) to emulate operation of the component. The automation logic may be certified using the playback of the recorded test signals. A system for testing the safety automation logic includes the controller, host machine, and TSGM. The host machine records the control signals and plays back the test signals on the controller to emulate operation of the component. The automation control logic may be certified using the test signals, e.g., by comparing these to the test specification or standard.

摘要： A system for generating platform-specific control logic implementation code for execution on a programmable logic controller (PLC) platform includes a plurality of processing layers. A first layer models generic control requirements as a unitary mathematical model (UMM). A second layer translates the UMM into generic control code describing a platform-independent set of generic control functions following an open structured language. A third layer automatically transforms the generic control functions into the platform-specific implementation code executable on different PLC platforms. A method of generating the implementation code includes modeling control requirements as a mathematical model, transforming the model into platform-independent control code describing a predetermined set of generic control functions using Extensible Markup Language (XML) schema, and automatically transforming the generic control functions into the implementation code.
