Stages of system modeling. - Modeling of systems

Stages of system modeling.

Consider the basic stages of modeling the system H, which include: the construction of a conceptual model of the system and its formalization; algorithmization of the system model and its machine implementation; obtaining and interpreting the results of modeling the system.

The relationship of the above stages of modeling systems and their components (sub-stages) can be represented in the form of network -

th graph, shown in Fig. 3.1. We list these sub-steps:

1.1 - statement of the problem of computer simulation of the system;

1.2 - analysis of the problem of modeling the system; 1.3-definition of requirements to the initial information about the object of modeling and organization of its collection; 1.4 - hypotheses and assumptions; 1.5 - definition of parameters and variables of the model; 1.6 - establishing the main content of the model; 1.7 - justification of the criteria for evaluating the effectiveness of the system; 1.8 - determination of the approximation procedures; 1.9 - a description of the conceptual model of the system; 1.10 - verification of the reliability of the conceptual model; 1.11 - preparation of technical documentation for the first stage; 2.1 - construction of the logical scheme of the model; 2.2 - obtaining mathematical relationships; 2.3 - verification of the reliability of the system model; 2.4 - selection of tools for modeling; 2.5 - drawing up a plan for the execution of work on programming; 2.6 -Specification and construction of the program scheme;

2.7 - Verification and validation of the program scheme;

2.8 - carrying out the programming of the model; 2.9 - validation of the program; 2.10 - preparation of technical documentation for the second stage; 3.1 - planning a computer experiment with the system model; 3.2 - definition of requirements for computing facilities; 3.3 - performance of working calculations; 3.4 - analysis of the results of modeling the system; 3.5 - representation of simulation results; 3.6 - interpretation of simulation results; 3.7 - summing up the results of modeling and issuing recommendations; 3.8 - preparation of technical documentation for the third stage.

Thus, the process of modeling system 5 is reduced to performing the listed sub-steps grouped in three steps. At the stage of constructing the conceptual model M to and its formalization, the modeled object is studied in terms of identifying the main components of the process of its functioning, the necessary approximations are determined and a generalized scheme of the model of system 5 is obtained. is transformed into the machine model M m in the second stage of modeling by sequential algorithmization and programming of the model. The last third stage of the system simulation is reduced to carrying out work calculations on a computer using the selected software and hardware, obtaining and interpreting the results of modeling the system 5, taking into account the effect of the environment Е. Obviously, when constructing the model and its machine implementation when obtaining new information, it is possible to review previously adopted decisions, i.e., the modeling process is iterative. Let's consider the contents of each of the stages in more detail.
