Claim One:
1. A method of aligning an on-line process run to a process model having a model trajectory for each of a multiplicity of process variables, the method comprising: receiving, at a computer device, value data from the on-line process run indicative of a current value for each of the multiplicity of process variables; storing the received value data from the on-line process run in a computer readable memory; for each of the multiplicity of process variables, using the computer device to analyze the value data to determine a distance between the process variable of the on-line process run when at a most recently determined model scan position and a model trajectory value for that process variable within the process model, at each of a plurality of model scan positions; using a computer device to sum the distances determined for the multiplicity of the process variables for each of the plurality of model scan positions, to produce, for each of plurality of model scan positions, a summed distance representing a sum of the distances determined for the multiplicity of process variables at a single model scan position; using a computer device to determine a minimum summed distance; and selecting the model scan position associated with the determined minimum summed distance as the model scan position to which the on-line process run is currently aligned.
