Abstract. The methods of specifying transformations such as specialization, interpretation, specification, and implementation of a generalized constructive-production structure are proposed. It is shown how to use these methods to construct grammatical constructive-production structures, which are analogs of well-known grammars, their modifications, and grammar-like systems. Various types of formal grammars are analyzed and synthesized. Refs: 19 titles.

Keywords: constructivism, formal grammar, constructive-production structure, specialization, interpretation, concretization.
