Mathematical methods of modeling research of the principles of technical systems

Summary. Consider the basic problem to query the database for the physical effects of the data. Technical problem may be simplistically represented as three components: the initial state, the end result, the process of converting the initial state to the final result. The problem arises if at least one of the components is unknown. Discarding cases where all the components are known, or all of the components are not known, we obtain a classification of technical problems, consisting of six types. In forming a set of queries to the database is a natural requirement for completeness of this set, i.e. Requests should be set to cover the technical challenges of all six types. With a view to the formulation of a complete set of queries we draw an analogy between the description of the technical problem and a description of the physical effect. Let us compare the initial state of the physical input action effect, the end result - the output of, the process of transformation of the initial state to the final result - a physical object or a sequence of physical effects. The requirements to the database on the physical effects: extensibility and improvement of the software and data structures without significant alterations of previously written programs and stored data, the ability to solve problems in a dialogue mode. A base structure consisting of a global database and a number of local databases that are generated to solve individual problems. A set of queries that cover the basic solution of technical problems at the level of principle. The problem of the search of the principles of device to convert the given source exposure to the specified output result. The structure of the local database to solve this problem and proposed a search algorithm. The main characteristics of the implementation of the algorithm.
