Description
In the article, the embodying of operation of integrating of systems, being generalization of operation of integrating of sets within the limits of system generalization of the theory of sets is considered. This operation is similar to bulean integrating operation of the classical theory of sets. However, unlike the classical theory of sets, the concrete algorithm of integrating of systems in its system generalization is offered and the quantitative standard system effect (synergetic, emergetic) arising with the application of integrating of systems is proved. For this standard, the unique name is offered: «The generalized coefficient of emerge by R.Hartley» because of likeness of its mathematical form to the local coefficient of emerge by Hartley, reflecting a degree of difference of system from the set of its base elements. The reference to the author's program realizing offered algorithm and providing numerical modeling of integrating of systems at various restrictions on complexity of systems and at various power of generating set is given, some effects of numerical modeling are given

THEORETICAL ASPECTS OF CREDIT RATING OF AGRICULTURAL COMMODITY PRODUCERS
Description
The article is devoted to the problems connected with credit rating of growers of agricultural products for which reception of credits is of great importance. In the article various treatments of "credit status" concept are considered, features of agricultural production are allocated. In the article it is concluded that the account of branch specificity of agricultural manufacturers will help banks to minimize their credit risks at work with the given clients
