Ontognoseological aspect of the problem of constructive covention

The article considers theoretical implications of the representative model considered both from her ontologic characteristics and in respect of its compliance to a relevant code of epistemological identity. Development of scientific and technical progress brings technical rationality which is characterized by a special ratio of objective prerequisites and subjective mental attitudes. The article considers the factors of an intrinsic determinism revealing regularities of functioning of the representative models forming the field of technical rationality. The concept of the technodinamic apriorizm characterizing semantic and logical coherence by the act of a reflection of technical consciousness is entered and proved. The principle of the technodinamic apriorizm is implemented in the representative models which are based on the idea of operational understanding of opportunities of human mind.
