The manual discusses issues that allow you to comprehend the processes of simulation modeling as part of the global processes of understanding the world, and the results of modeling are part of the process of forming managerial decisions in the economy. Therefore, the main attention is paid not so much to the technique of computational procedures and algorithms as to the understanding of their systemic meaning, i.e. presenting them as a system.By design, this material is considered as an addition to existing courses on simulation modeling. Many sections of the manual are presented in the manner of inviting students to a dialogue with the prospect of their possible development of the material in their subsequent scientific work. And such a perspective requires a systematic approach.In addition, the last chapter considers a method for solving the problem of analyzing the sustainability of enterprise cooperation based on tensor methodology. This section should be considered in terms of the usefulness of introducing students to some effective methods for analyzing the sustainability of industrial cooperation, but beyond the scope of the relevant training courses.The manual is intended for students, graduate students and researchers who seek to broaden their horizons, develop a systematic vision and understanding of such a complex, ambiguous and actively developing area of science as simulation modeling.
