The paper describes the control method of the production facilities (baking chamber) under uncertainty. Due to the impossibility to find the adequate analytical model for this object, to control this type of the object under uncertainty the Mamdani fuzzy model is applied. A distinctive feature of this paper is connected with following: the parameters of the fuzzy model can be determined inaccuracy by the experts and, therefore, the model can work insufficiently, in order to eliminate the possibility of inaccuracy, the problems of assessment of the fuzzy model adequacy and the updating of its parameters are discussed. The iterative algorithm for the updating of the parameters of the described model is designed. The base of the iterative algorithm is connected with probability theory and mathematical statistics. Justification of application of the probability theory criteria is fulfilled. The research of the fuzzy model's work with the application of the updating block of the model's parameters is fulfilled and assessment of the fuzzy model's work is carried out by the usage of the probabilistic criterion (mean square deviation of the fuel consumption in the baking chamber). The updating process consists in correction of the membership functions according to the fulfilled experiments.
