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 article features revealed pricing for machine building products. The general approach to modeling the process of pricing for machine building products within the parameters of the demand for goods produced using this product. The building model performance optimization criterion prices and volumes of sales machine building company. Established the possibility of using performance optimization criterion prices for machine building products to address the task of selecting the best varieties of products.
