Invensys Ltd. is a multinational engineering and information technology company headquartered in London, United Kingdom. It was formed in 1999 through the merger of BTR plc and Siebe plc. It has offices in more than 50 countries and its products are sold in around 180 countries. It was taken over by the French multinational Schneider Electric for a total consideration of £3.4 billion in January 2014. Schneider plan to replace the "Invensys" name with their own, therefore the "Invensys" brand name shall be phased out. Invensys lines of business are grouped into four segments: Software, Industrial Automation, Energy Controls and Appliance. Its brands include Avantis, Eurotherm, Foxboro, IMServ, InFusion, Triconex, SimSci, Skelta, Wonderware, Drayton, Eberle, Eliwell. Wikipedia.


A method and system for automatically generating simulations for a distributed control system is disclosed herein. A programmed process model generator automatically incorporates a variety of process model data from pre-defined model libraries into descriptions of process equipment including control devices to render simulation models of various degrees of fidelity.


Controlling and optimizing industrial processes by integrating MPC-based approaches and expert system approaches. At least two different control variables with identical models are used. An expert system adjusts at least one of the control variables to change a setpoint or range or the like while standard MPC techniques change another control variable to address appropriate classes of control problems.


A manufacturing execution system (MES) for providing an indication of the performance of the line. The MES includes a configuration module for modeling entities and lines containing the entities. The MES also includes a runtime module configured to determine the entities on the line whose production can be extrapolated to evaluate the performance of the line. In some cases, the MES determines which of the entities on the line limits the performance of the line; in other cases, the MES determines which of the entities has a production amount that best represents that of the line. The MES is operatively connected to field inputs associated with the entities that provide production data for the entities. Using the production data for the entities chosen to represent the line, the MES generates production metrics representative of the performance of the line and displays them to MES users.

A manufacturing execution system (MES) for selectively controlling the display of MES content. The MES displays a first view with data about a first aspect of an industrial process and determines whether the user is authorized to view data about a second aspect of the industrial process related to the first. An inactive informational display item is generated when the user is not authorized to view the data about the second aspect. The informational display item provides a visual indication of the relationship between the first and second aspects and is non-selectable for navigating to another display. An active navigational display item is generated when the user is authorized to view the data about the second aspect. The navigational display item provides a visual indication of the relationship between the first and second aspects and is selectable for navigating to a second view including data about the second aspect.

A system is provided. The system comprises a computer system comprising at least one processor, a thermodynamic state solver application, and a thermodynamic system solver application. When executed by the at least one processor, the thermodynamic state solver application computes a flash equilibrium state solution for each of a plurality of nodes in a thermodynamic network and determines for each of the plurality of nodes at least one sensitivity of a first thermodynamic property with reference to at least one second thermodynamic property. When executed by the at least one processor, the thermodynamic system solver computes a pressure at each of the nodes and flows between the nodes based at least in part on the sensitivities, wherein a result based on the pressures and flows is determined.
