Modeling of the problem area of space imagery planning is carried out within the framework of a complex purposeful system – the space system – by means of specialized automated systems, also being purposeful systems. For modern purposeful systems, both achievements and significant shortcomings are characteristic. In purposeful systems, software and hardware are widely used, and their application is rapidly increasing. For software and hardware are also significant achievements and serious problems. In these conditions, it is necessary to provide a guaranteed qualitative modeling of the problem area of space imagery planning. At the same time, to ensure the quality of modeling, it is necessary to constantly raise the level of standardization.
Practical experience in solving space planning problems allows us to assert that the approach of radical modeling, the application of the language of radical modeling schemes RADICAL, is to ensure a guaranteed quality of modeling of the relevant problem area. The purpose of this work is to substantiate the approach to providing a guaranteed qualitative multidimensional modeling of the problem area of space survey planning based on the language of the RADICAL radical modeling schemes.
Radical modeling is focused on the creation of a single mathematical support for purposeful systems and for its implementation with the help of software and hardware, for standardization, unification, cataloging and certification of the means used in the problem domain of purposeful systems based on the application of mathematical models and methods. Radical modeling relies on the concept of the environment of radicals A.V. Chechkin. The basic concept of the concept of a radical environment is the concept of a radical – a system that can reside in two types of states: it is included (used for its intended purpose); Off (not used). Introduced standard radicals: unique and containers. Unicom correspond to the components of the problem area, containers – their properties and connections. Many radicals form a medium of radicals – many interconnected significant components of the problem area. To represent the environment of radicals, its parts ("sections"), a special formalism is used – the language of radical modeling schemes RADICAL. In the RADICAL language, the radical environment is represented by a structure called the radical scheme. There are different representations of the schemes of radicals. For example, symbolic, geometric (vector) and tabular. Automated systems model the problem area of the CA, applying the following types of support: mathematical; Software (general and special); Technical; Information; Linguistic; Methodical; Organizational; Ergonomic; Legal. The RADICAL language used in the AC allows you to represent (model) all the components of all kinds of AS services, all the significant components of the CA problem area, all their significant properties and connections, all the transformations of the corresponding formalized descriptions.
The key problem of purposeful systems, software and hardware of purposeful systems is the problem of providing information and system security, which requires, among other things, the organization of effective attempts to solve supernumerary tasks. Let the provision of information and system security – the intellectualization of purposeful systems based on the formalization of their problem area and the implementation of formal descriptions using software and hardware.
The problems that occur for purposeful systems, for software and hardware, indicate that this problem area has not been studied enough. Systematic studies of the problem area of purposeful systems, including space systems (in our case, in part of the space survey task) are needed.
The survey objects located on the earth's surface are surveyed within the scope of the spacecraft's survey.
In order to shoot, the spacecraft (along with the survey equipment) rotates around its longitudinal axis at acceptable angles. Definition of the removed objects is made based on the given system of rules. As examples, some typical schemes of radicals, isolated from the analysis of the problem area of space imagery planning, contain significant components of this area and significant connections that take place between them.
The analysis of the problem area of space survey planning, the typical radical schemes identified as a result of this, as well as the practical experience with working with radical schemes for the development and modification of software allow us to state that the approach to assuring the guaranteed qualitative multidimensional modeling of the problem area under consideration, Schemes of radical modeling RADICAL is reasonable and practical from a practical point of view. The use of radical modeling serves to increase the level of standardization and unification, which is necessary to ensure the quality of modeling.
