The functioning and design of dialog itinerary systems

The paper is concerned with dialog problem-oriented systems to be referred to as itinerary which are mergers of special-purpose packages of application programs. The way to control programmed components of the packeges, or computation steps, are described in detail and main stages in generation of itinerary systems are explained. The computation process in packages is controlled in compliance with models of subject areas which are specified as graphs of a certain kind.
