Abstract: This study describes the developed methods for finding the solutions based on the direct and reverse output by the example of an expert tool system ExPRO. The method of finding solutions with a variable strategy is proposed which is considered to improve the level of automation increase, the creation of a knowledge base and to address potential inconsistencies instrumental system strategies by the methods of an expert solutions. Formally, the opportunities for direct and reverse output in the search for solutions with a variable strategy are described and proven by setting certain parameter values. The conditions of a strategy selection and the methods for finding the solutions to determine the parameters of the search process depending on these conditions are developed. For one of the conditions the statement of possible selection for any of the strategies considered and its proof also presented the advantages and disadvantages of each strategy selection in this case. For all conditions the examples of knowledge bases are brought created in the system ExPRO as a graph of rules related on the basis of input and output variables. The results of solutions obtaining tests are shown with the variable strategy and the comparison of its effectiveness with direct and reverse output by the percentage of solved problems and the time of goal search.
