In this paper,we considercontrol methodsthat occur in extreme (emergency) situations of the dynamic environment of the production facility. Moreover, we consider the logical and transformational rules of the control algorithm of individual processes and BPS as a whole. We propose to use the methodology of situational management, which means that the set of all states (situations) is conditionally divided into the set of normal and abnormal situations. Furthermore, we considerthe necessity of the joint use of various methods (situational, optimal, guaranteed result) at the appropriate stages of a solution ofthe control problems. Logical-transformational rules of the control algorithm for individual processes are described.According to the results of the study of the main stages in the development of situational management, the situational management played a catalytic role, bringing new ideas to life as well asprinciples for constructing models of control objects.
