This report is observed sequential optimization method of discrete functioning processes (FP) in man-machine systems (MMS) on the basis of probabilistic and fuzzy indexes of effectivity, quality and reliability (EQR) of MMS functioning. This method is applied in tasks of object's control. Properties of monotonous recourse of this indexes, common scheme of optimization method in the bounds of production-predicate model (knowledge base), including required clauses of altematives optimality and possibility are observed. There are found power estimation of nondominates altemalives area (optimally by Pareto) and costs of sequential analysis method, which used with select of optimal selection strategy.
