This article considers the problem of optimizing the control and management system performance for a complex object. An industrial network with various resource flows is considered as a complex system. The production process model is represented by a fuzzy temporal graph. The fuzzy temporal graph makes it possible to consider the change in parameters over time, which affects the efficiency of the system under uncertainty. The possibility of applying the theory of fuzzy sets to describe the production process in the form of variations of route maps is analyzed. To evaluate the efficiency of the system, the production problem was formalized in a fuzzy form. The calculation of the duration of the route charts of the technological process was carried out, the maximum conjunctive strength and the degree of internal stability were estimated.
