The article presents the results of a study of RTO class systems, their position in the hierarchy of decision-making systems. The tools used in solutions of this class are considered. The purpose of the work is to form a picture of RTO systems applicability in technological processes, to understand their differences from decision-makings of the APC class. The RTO system is aimed to optimize the technological process taking into account current economic prerequisites. The RTO loop is an add-on for control systems and consists of steady state detection tools, data reconciliation, measurement validation and process optimization based on a first-principle process model. Examples of the use of RTO systems in petrochemical plants and RTO decision-makings optimization scenarios are presented. RTO decision-makings are effectively applied in non-linear processes with a large number of limitations, changing equipment parameters and price prerequisites. Such processes are steam cracking, catalytic cracking, crude distillation, etc.
