An apparatus and method for monitoring a process involve development and application of a statistically qualified neuro-analytic (SQNA) model to accurately and reliably identify process change. The development of the SQNA model is accomplished in two stages: deterministic model adaption and stochastic model modification of the deterministic model adaptation. Deterministic model adaption involves formulating an analytic model of the process representing known process characteristics, augmenting the analytic model with a neural network that captures unknown process characteristics, and training the resulting neuro-analytic model by adjusting the neural network weights according to a unique scaled equation error minimization technique. Stochastic model modification involves qualifying any remaining uncertainty in the trained neuro-analytic model by formulating a likelihood function, given an error propagation equation, for computing the probability that the neuro-analytic model generates measured process output. Preferably, the developed SQNA model is validated using known sequential probability ratio tests and applied to the process as an on-line monitoring system. Illustrative of the method and apparatus, the method is applied to a peristaltic pump system.

In an order processing system, mechanisms and techniques receive a change to an existing order in the order processing system and generate a change order based on the existing order. The change order includes the change to the existing order. The system can then compare the change order to the existing order to generate change order result that indicates differences between a change order in the existing order. The system then provides the change order result to at least one recipient such that the recipient may distinguish the differences between a change order in the existing order. Since a change to an existing order can result in changes other than those specifically specified in the received change, the system of the invention allows a person making the change to be presented with the change order results that convey all of the changes that result to the existing order.

A method of creating and using an adaptive DMC type or other MPC controller includes using a model switching technique to periodically determine a process model, such as a parameterized process model, for a process loop on-line during operation of the process. The method then uses the process model to generate an MPC control model and creates and downloads an MPC controller algorithm to an MPC controller based on the new control model while the MPC controller is operating on-line. This technique, which is generally applicable to single-loop MPC controllers and is particularly useful in MPC controllers with a control horizon of one or two, enables an MPC controller to be adapted during the normal operation of the process, so as to change the process model on which the MPC controller is based to thereby account for process changes. The adaptive MPC controller is not computationally expensive and can therefore be easily implemented within a distributed controller of a process control system, while providing the same or in some cases better control than a PID controller, especially in dead time dominant process loops, and in process loops that are subject to process model mismatch within the process time to steady state.

A crossbar switch (50) is implemented in a reconfigurable circuit, such as a FPGA, instantiated with a number of modules (40), the crossbar switch (50) providing communication links between the modules (40). The modules (40) and crossbar switch (50) can be easily updated in a partial reconfiguration process changing only portions of modules (40) and the crossbar switch (50) while other portions remain active. The crossbar switch (50) uses individual wiring to independently connect module outputs and inputs so that asynchronous communications can be used. The crossbar switch (50) can be implemented in different embodiments including a Clos crossbar switch, and a crossbar switch connecting each module output only to a corresponding module input, allowing for a reduction in the amount of FPGA resources required to create the crossbar switches.

Systems and methods for using comparisons of empirical system data, (e.g., performance, accounting, software module or function frequency), for testcase and workload profiling are provided. Instead of asking a customer what he does, simply asking for some set of empirical data that can be formatted, reduced, and analyzed. By gathering the same kind of data for the test systems that is used by the customer, testcases and workload profiling are improved by making comparisons between the customer data and the test data in an iterative process. The iterative processes change test data and compare not only customer data with test data but also compare data from prior iterations with current data. There is a feedback loop for providing a comparison of how close or distant the testcases and workload profiling are from customer-like data and workloads in a particular test.
