The paper deals with the assessment of a surface water quality in the Kherson region, as well as the assessment of a technogenic load on the surface water bodies by the volumes of the wastewater and pollutants discharges over a long period of time. The problem of supplying the regions of Ukraine with water is urgent for many regions, including the Kherson region. The materials from the Regional reports, Ecological passports on monitoring a state the surface water as well as the data on the volumes of the sewage and pollutants discharges were used as baseline data.
Aim. The research aims to develop a method of optimal PI-controller tuning, which allows to take into account the constraints and to minimize the undesirable indicators of the automatic control quality. Method. In order to carry out the investigation, the problem of optimal PI-controller tuning was stated in a general form. The analysis of the elements of the problem has been conducted. It allowed substituting the elements to the requirements of individual minimization criteria.
The freshness of the meat is one of the indexes of its quality. However, it is often frozen to be transported and stored. After unfreezing, it is offered to a consumer as a fresh one. Quality of that meat is worse, but the price is, mainly, identical to the cost of meat that wasn’t frozen.

The example of improvement of the mathematical model of monitoring of difficult objects of technique and medicine with the low level of dynamics of processes is examined. The article of researches is normative documents, which should be expediented to specify and perfect on the basis of thein formation, got as a result of analysis of results, mathematical models of monitoring of difficult objects of technique, medicine got with a help with the low level of dynamics of processes.
The presence of fatigue cracks on the surface of metallic underground pipelines sharpens the problem of calculation values of strength characteristics at the action of corrosive environments, that did not find the complete decision nowadays. In this connection it is needed to correct the row of defects and normative and technical documents related to insufficient actuality of corresponding.
