The developed auxiliary software serves to simplify, standardize and facilitate the software loading of the structural organization of a complex technological system, as well as its further manipulation within the process of solving the considered technological system. Its help can be especially useful in the case of a complex structural organization of a technological system with a large number of different functional elements grouped into several technological subsystems. This paper presents the results of its application for a special complex technological system related to the reference steam block for the combined production of heat and electricity.

BACKGROUND Nutrition recommendations in patients with type 2 diabetes mellitus(T2Dm)are to consume rye or integral bread instead of white bread.A positive effect on glucoregulation has been achieved by enriching food with various biologically active substances of herbal origin,so we formulated an herbal mixture that can be used as a supplement for a special type of bread(STB)to achieve better effects on postprandial glucose and insulin levels in patients with *** To compare organoleptic characteristics and effects of two types of bread on postprandial glucose and insulin levels in T2Dm *** This trial included 97 patients with T2Dm.A parallel group of 16 healthy subjects was also *** participants were given 50 g of rye bread and the same amount of a STB with an herbal mixture on 2 consecutive *** blood glucose and insulin levels were compared at the 30^(th),60^(th),90^(th) and 120th min.A questionnaire was used for subjective estimation of the organoleptic and satiety features of the two types of *** Compared to patients who consumed rye bread,significantly lower postprandial blood glucose and insulin concentrations were found in T2Dm patients who consumed *** relevant differences were found among the healthy *** estimated organoleptic and satiety characteristics are better for STB than for rye *** STB have better effects than rye bread on postprandial glucoregulation in T2Dm *** estimated organoleptic and satiety characteristics are better for STB than for rye ***,STB can be recommended for nutrition in T2Dm patients.
