PERA Reference model: Decision-making and control hierarchy, 1992. Purdue Enterprise Reference Architecture (PERA), or the Purdue model, is a 1990s reference model for enterprise architecture, developed by Theodore J. Williams and members of the Industry-Purdue University Consortium for Computer Integrated Manufacturing.
This framework is based on a division of the model into description views and levels, which allows a description of the individual elements through specially designed methods, without having to include the entire model. The methodology serves as a systems development life cycle for mapping and optimizing business processes. These processes are ...
For example, a symbol of a pump can show the operator that the pump is running, and a flow meter symbol can show how much fluid it is pumping through the pipe. The operator can switch the pump off from the mimic by a mouse click or screen touch. The HMI will show the flow rate of the fluid in the pipe decrease in real time.
An ICD is the umbrella document over the system interfaces; examples of what these interface specifications should describe include: The inputs and outputs of a single system, documented in individual SIRS (Software Interface Requirements Specifications) and HIRS (Hardware Interface Requirements Specifications) documents, would fall under "The Wikipedia Interface Control Document".
The WELL Core is for the building that provide tenant occupation more than 75%, and not needed to achieve minimum points from every subjects. [3] The WELL Silver, Gold, and Platinum level must achieve at least 1, 2, and 3 points per subject, but the WELL Bronze has no minimum points' rule. For WELL core, there are no minimum point. [3]
Trump’s reciprocal tariff plan is ... the differences were sizable. On autos, for example, the U.S.’s most-favored-nation tariff stands at 2.5 percent, versus 10 percent for the European Union ...
GOMS is a specialized human information processor model for human-computer interaction observation that describes a user's cognitive structure on four components. In the book The Psychology of Human Computer Interaction, [1] written in 1983 by Stuart K. Card, Thomas P. Moran and Allen Newell, the authors introduce: "a set of Goals, a set of Operators, a set of Methods for achieving the goals ...
Example of a continuous flow control loop. Signalling is by industry standard 4–20 mA current loops, and a "smart" valve positioner ensures the control valve operates correctly. The processor nodes and operator graphical displays are connected over proprietary or industry standard networks, and network reliability is increased by dual ...
