Aerospace Instrument-Making Annotation << Back ANALYSIS AND JUSTIFICATION OF RELIABILITY REQUIREMENTS FOR PERSPECTIVE SPACE VEHICLES L.E. Mistrov, E.M. Shepovalov A method for structural synthesis of the software of aviation multifunctional simulators for training crews of aircraft is proposed, including physical and mathematical in terms of integral efficiency indicator “number of solved training problems” statement of the problem, methodological approaches to solving the synthesis problem using a formal mathematical apparatus and apparatus of fuzzy sets, the basis of the system presentation of the software structure, the structure of the method for evaluating the effectiveness and modeling of the software structure. The method is based on the methods of analysis and synthesis of complex systems, decision making, resource allocation, optimization, hierarchical decomposition, Pareto, goal tree and analytical calculations. Keywords: multifunctional flight simulator, training task, software, elementary technological operation, software component, performance indicator, performance criterion, structural synthesis, modeling.
