A method is proposed for structural and parametric synthesis of software for aviation multifunction flight simulators (AMT software), aimed at substantiating the configuration (the combined goal of software components (PCs) and their interconnections) and the main software parameters, providing the choice of the optimal version of its configuration to perform a given set of training tasks in some subject area. The method represents a hierarchical system of interdependent mathematical models of structural, parametric and structurally-parametric synthesis proper, which ensures the interconnection of all structural software. The software includes a hierarchical set of interconnected related goals (functional tasks) special, private and general PCs, obtained on the basis of an additive «mixture» of elementary technological operations. It is shown that the choice of software configuration is based on a mathematical model that provides the construction of a set (area) of acceptable options and the optimal choice of the maximum number of completed educational tasks, based on the methods of optimal resource allocation, discrete optimization, and the maximum element taking into account functional, criterial and parametric restrictions.
A method for structural synthesis of software is proposed, based on its presentation based on the principle of a hierarchical multilevel description and consideration of compositional, effector, and reflective properties in the form of a complex multilevel aggregate of particular problems of PC synthesis based on the optimal distribution of the total resource. It has been established that the implementation of the method is based on the principle of sequentially increasing the capabilities of software and comes down to determining the qualitative and quantitative composition of PCs on a variety of variable application methods and the main characteristics of AMT. Since there is a complex deterministic monotonic relationship between the criterial functions of software, the synthesis method uses the principle of narrowing the set of private extremes and converting them into an integral indicator of AMT efficiency. The method of parametric synthesis of software based on the hierarchical conversion of particular results of the synthesis of PC configurations based on a system of models and methods for evaluating the effectiveness of software options as part of a different type of PC as a function of the educational task to be solved is disclosed. The search is carried out on the set of acceptable PC variants satisfying the optimality condition - a system of preferences arising from the aggregate representation from the level of external synthesis of AMT. In this case, the formalization of PC functions is presented in the form of ranked private quality indicators based on their contribution to the efficiency of AMT, and preference relations based on Pareto binary relations. It is shown that, based on the description and sequential analysis of private PC quality indicators, by constructing the inverse mapping of their criterion functions, a set of maximum values of their parameters is constructed that provide a reasonable choice of PC parameters.
It is shown that the basis of the method of structural-parametric synthesis of software is its presentation in the form of a hypergraphic diagram of PC parameters and ensuring their interconnections using the transition function (matrix) in solving functional problems. The method is based on the algorithmic sequence of research stages presented in the form of a software synthesis technological scheme. The stages of the synthesis of PCs are realized simultaneously, providing «embedding» in each other, alternately fulfilling the main role. As a result of such a multiply connected reciprocating movement through the stages and within each stage of the software synthesis, a cyclic iterative process with a dynamic hierarchical structure is formed, which provides the gradual establishment of properties and quality indicators and the achievement of the resulting idea of the appropriate configuration of AMT software.
