1. A system for on-line monitoring of operation of a process in a process plant having a process control system to control the process in connection with process measurements indicative of the operation of the process, the system comprising:

  • a process simulation module to model a plurality of physical devices within the process plant for generation of model data indicative of a simulated representation of the operation of the process;

    an analysis module to implement a multivariate statistical analysis of the operation of the process based on the model data and the process measurements;

    one or more computer-readable media to store respective configurations of the process simulation module and the analysis module; and

    , one or more computer-executable execution engines for implementation of the respective configurations of the process simulation module and the analysis module to enable the on-line monitoring of the process based on communications with the process control system during the operation of the process.
