Abstract: A method for simulating the insertion of a data storage medium into or removal of a data storage medium from an input/output station, alternatively referred to as an import/output station. In one application of the invention, a data storage resides in an I/O station slot. A first variable corresponding to this slot is modified to indicate that the slot is actually empty. A command is issued indicating that the I/O station has been accessed, triggering a scan of the slot by an automated robotic accessor. Since the accessor will detect that the slot is, in fact, full, it will report this status to a library manager which will, in turn, update the first variable. The action of updating this variable is reported to associated devices such as a host computer, host application, or other associated device. In this manner, the operation of the library manager and devices receiving status information may be tested without requiring that a physical data storage medium actually be removed and re-inserted.

The methodology includes a combination of process control steps and data analysis techniques to investigate responses to controlled “black box” process inputs, e.g., coal and air feeds for coal-fired furnaces in the case studies above. A unique time-dependent perturbation is applied to individual process feed streams to give a signature in the data that permits the filtering and detection of various measured responses, e.g., continuous emission monitor readings for NOx, SO2, CO2, CO, and opacity for regulated electric utility furnaces. The perturbation is implemented using the plant control system. Individual control signal set points are perturbed for each piece of equipment supplying process inputs of interest. As a result, complex commercial processes can be evaluated for optimization without changing the normal configuration of the system.
