Although the advisory systems are mostly applied to narrow specialized domains, in many cases the presentation of a problem in one particular expert base leads to its considerable oversizing. Thus, according to Authors' opinion, a possibility ot modular and hierarchic structure of knowledge base should be considered just at the stage of conceptual statement ot the problem. Such a structure would be quite easy to obtain sis the language of typical E-Shell programmes enables the junction of many different knowlegde bases.
