Dear colleagues,

I’m pleased to present to you our new electronic journal, System Informatics.

Since 1991, our research institute has been publishing the System of Informatics series, which contains surveys and basic research works by Russian and foreign authors covering various aspects of computer science, programming and information technologies.
