Summary: The article is dedicated to the research of biotechnical systems. The selected method of study takes into consideration in what extend the viewed bio objects being objectively evaluated. It is proposed to use optimal control method for this purpose. Once the parameters of biotechnical system are determined, the most effective control is being ensured which maximizes optimization criteria. Depending on the nature of admissible multitude the problems of mathematical programming are being solved. The results of findings are being analysed.
Keywords: bio-objects; biotechnical system; optimal system; optimal control.
