Abstract The article deals with the topic of development of the instrumental tools and methods for design of the adaptive user-interfaces. The device for interface design based on automatic circuit analysis is considered by the authors. The also article implies requirements for graphic editor to design interface structures and schemes for user circuits breakdown. The algorithmic structure of the applications is formalized in a form of Petri nets. The article provides analysis of the temporal characteristics optimization for implementation of user requests through dynamic clustering of the resources. Authors of the article suggest formalization in the form of Markov's chain which calculates the initial probability distribution of access to system resources.
