Validation of the heuristic approach in machinebpiece locating. Second part

The various decisions are collected in the paper such as a choice of a problem, extraction, structuring and formal description of knowledge in domain of interest and experts actions. These decisions have been accepted by working out the prototype of the expert system for the selection of locating chart. The pragmatist of the outlined research consists in decreasing the risk of inadequacy of the models which are constructed by the expert and on the basis of reasons of common sense. Multi-faceted methods were used, from vector algebra to the theory of lattices. In the first part of paper the expediency of expert system development is proved and her rulebase is systematized. In the second part there are proved information models of knowledge domain. They determine the database scheme and operational basis of expert system program realization.
