ABSTRACT:
A method for monitoring operation of a process facility comprising the steps of storing at least one planned sequence of hypothesized plant states using multi-valued logic to define calculation of a congruence factor for each of the hypothesized plant states; wherein said storing step includes storing relationships between the multi-valued logic variables defined by a maximum value function when any of the multi-valued logic variables in a first relationship may be true and defined by an average function when all of the multi-valued logic variables in a second relationship are expected to be true; converting data from the process facility into values of multi-valued logic variables; wherein said converting step assigns to the multi-valued logic variables numerical values corresponding to likelihood of truth; calculating the congruence factor for each of the hypothesized plant states in the at least one planned sequence using the multi-valued logic variables; and identifying a current plant state by comparing the congruence factor of each of the hypothesized plant states based and selecting the state having the highest congruency factor.
