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.

An adaptive multivariable process control system includes a multivariable process controller, such as a model predictive controller, having a multivariable process model characterized as a set of two or more single-input, single-output (SISO) models and an adaptation system which adapts the multivariable process model. The adaptation system detects changes in process inputs sufficient to start an adaptation cycle and, when such changes are detected, collects process input and output data needed to perform model adaptation. The adaptation system next determines a subset of the SISO models within the multivariable process model which are to be adapted, based on, for example, a determination of which process inputs are most correlated with the error between the actual (measured) process output and the process output developed by the multivariable process model. The adaptation system then performs standard or known model switching and parameter interpolation techniques to adapt each of the selected SISO models. After the adaptation of one or more of the SISO models, the resulting multivariable process model is validated by determining if the adapted multivariable process model has lower modeling error than the current multivariable process model. If so, the adapted multivariable process model is used in the multivariable controller.

A process such as a snapshot creation application process freezes a file system upon initiating a process to create a snapshot of a file system or a part thereof. Upon freezing the file system, the snapshot application process causes a second process to make a change to the file system. If the change is successfully made before the snapshot creation application process tries to thaw the file system, the second process sends a signal back to the snapshot application. Upon receiving a signal from the second process, the snapshot creation application process outputs a warning to a user that the snapshot is inconsistent. The snapshot application also causes a third process to automatically thaw the file system, if a certain period of time has passed and the third process has not received a signal from the snapshot application process indicating the snapshot has been successfully created.

In an object oriented computer system, a framework mechanism defines a mechanism that separates the ability to complete a process from the results of that process. A task is defined in the framework in terms of a sequence of processes. The framework includes a coupling mechanism for flexibly coupling any of these processes together in any suitable order to define the run-time behavior of the framework without changing the core functions of the framework. The coupling mechanism includes the definition of a processable interface and a processing interface. A particular process generally takes detail information as input and produces detail information that is used in a subsequent process. The detail information input into a process is said to be "processable", and therefore implements the "processable" interface. The detail information output from a process is said to be "processing" detail that is output to the next process, and therefore implements the processing interface. Thus, an object that uses "shippable" detail information as input through its processable interface generates corresponding "shipping" detail information for each shippable detail, which is output to one or more subsequent processes via the processing interface. A particular processable can be associated with any processing interface that supports the processable interface. In other words, any process-related class in the framework can be coupled to any other process-related class, provided one class has a processing interface that corresponds to the processable interface of the subsequent class. In this manner, classes in the framework mechanism can be flexibly coupled together in any suitable order or fashion to accommodate a great variety of different configurations. The framework mechanism therefore provides a high degree of implementation while maintaining the ability to achieve a high degree of customization.
