The problem of the quality of automated systems can be solved both from a common standpoint and from the standpoint of ensuring the quality of individual system components (software, information security tools, etc.). However, this leaves a number of particular questions due to the characteristics of a specific automated system. The occurrence of errors in the automated system for the preparation of aircraft flight data can lead to irreparable losses, the most damage is caused by design errors and incorrect general solutions implemented at the stage of system development. This necessitated the identification of specific principles of system design and development. The developed principles of designing an automated system consist, firstly, in determining its reference result, secondly, in identifying the main types of data and ensuring controlling their syntactic and semantic correctness, and, thirdly, in correct defining the boundaries of the system. The theoretical basis for the principles of the development of an automated system is the provisions of the systems approach, in particular, the new application of the system stratification tool. A typical automated data preparation system is considered as an example. It is shown that the use of the proposed principles allows avoiding or minimizing design errors and miscalculations and bringing the system representation stratification to a level that allows obtaining the necessary initial data and evaluating the quality indicators of the output data

When designing automated systems for aircraft flight data preparation, many practical problems are solved by introducing either insufficient protection means or their redundancy. Both situations create information security vulnerability. On the basis of a number of publications analysis it is concluded that the basics of information security theory are reduced to the formulation of the main axioms, with the implication that there is currently no complete theory of information security of computer systems. As a result there are many issues, including issues of general nature, requiring some elaboration. The article considers a set of issues related to ensuring information security of the automated system for aircraft flight data preparation. The nature of two basic principles of information protection organization in this system is unraveled. The first principle requires consideration of all aspects related to the problem of ensuring information security of the system, and the second ― optimal control of means of information protection of the automated system of aircraft flight data preparation.

Nowadays methods for solving the problem of estimating the temporal characteristics of data processing are well studied and based on the timing performed operations, the use of the network graph, the construction of the spanning tree, etc. However, in solving some problems of automating controls, there may be difficulties associated with modeling the information processing and obtaining adequate input data for calculating the indicator of the timeliness of the system function implementation. The article considers general issues of assessing the properties determining the quality of aircraft flight data, its feasibility and timeliness. A new approach associated with the model "the presence of exactly one error in the generated data volume" is proposed for assessing the feasibility of aircraft flight data. This model is applicable only in the case when the control of feasibility is carried out for the entire set of necessary data. For timeliness index assessment, it is proposed to present the structure of the automated data preparation system in the form of a sequence of technological sites. Having determined the execution time of functional tasks by elements of a typical site and probabilities of data distortion, it is possible to calculate similar indicators for each elementary process included in the data preparation process and the system as a whole. An elementary data preparation process, the essence of which is to update the system database is considered as an example. This stage is the most representative, since all elements of the technological site are involved in its implementation.

Methods for solving the problem of ensuring the reliability of information have been considered in the works of many domestic and foreign scientists. Nevertheless, when performing some tasks of automation of the activity of the personnel of the governing bodies, it may be difficult to calculate the required value of data reliability due to the complexity of the algorithms for calculating the confidence indicator and difficulties in obtaining adequate input data. A new method for assessing the reliability of aircraft flight data is considered on the basis of the special representation of the data preparing process as a serial connection of technological sections in time and calculating the reliability indicators for each element of the technological section and the technological section as a whole. The structure of a typical technological section includes a documentalist, an operator, hardware, software and a procedure for correcting erroneous data detected by the control procedure. The use of such a process model allows obtaining a simple recurrent algorithm for estimating the data reliability index for any technological section using the reliability index values for the previous technology sections. Having determined the probabilities of data distortion and the time of operation performing by elements of the technological section, it is possible to calculate the values of similar indicators for each elementary data preparation process and the system as a whole. An elementary data preparation process, the essence of which is to update the system database is considered as an example. This stage is the most representative one, since all elements of the technological section are involved in its implementation

The quality of development and commissioning the automated system for preparing aircraft flight data (ASPD) depends on many factors, among which it is necessary to identify and justify those most significantly affecting quality of the system being commissioned. The practice of designing an ASPD has shown that the quality assessment based on its characteristics is nothing more than a consequence. This situation is due to the presence of deeper factors that will only appear during the operation of the system. To eliminate this situation, the problem is formulated as a task of determining the factors affecting the quality of development and commissioning the system, based on the data obtained by mathematical processing of expert estimates of each factor significance. To solve this problem, it is proposed to use the hierarchy analysis method. Developed on its basis the methodological approach makes it possible: – to identify the main factors significantly affecting the quality of the ASPD being commissioned, and to propose qualitative scales for assessing the degree of feasibility of each generic criterion; – to formalize a multi-criteria indicator of the degree of the ASPD quality compliance with the requirements of generic criteria and obtain its dependence on the levels of development and commissioning the system; – to justify the requirements for ASPD operational suitability, perform its evaluation, as well as determine the necessary measures for implementing the specified requirements on operational and technical characteristics of the ASPD.

The paper introduces a methodological approach to optimizing the automated flight data preparation system design process by using organizational and technical measures to minimize the number of design errors and miscalculations of an accidental and deliberate nature. The study proposes to build the structure of the system design process according to the principle “from the general to the particular”, based on which the connections between different stages of design are determined in the form of surjective and bijective correspondences. In the diagram of design stages of the automated data preparation system, each lower level of the hierarchy is a decomposition of the elements of the adjacent upper level into more specific elements. The main methods of improving the quality of system design, methods of semantic control of the correctness of the design decisions, and syntactic control of the correctness of the developed documentation for the design of the automated data preparation system are proposed. The main thirteen problems of system design are considered, which, in practical application, will acquire a more specific form and significantly improve the designed system’s quality.

The paper focuses on a methodological approach to identifying software in special software for systems of critical applications. The approach relies on the analysis of the subject area associated with the functioning of such systems. The term ‘software bugs’ is local and depends on the system into which they are embedded. In this regard, the methodological approach to identifying software bugs is illustrated by an automated system for preparing data for aircraft flights. By software bugs, we mean malicious software that can affect the algorithms for the functioning of the system, disrupting the normal mode of its operation and causing significant damage to the goals of the system. To find where software bugs are likely to be embedded, we specified actions which consist in understanding the features of assessing the quality of each of the main elements of the system and the essence of software bugs, with account for the features of the automated data preparation system; describing the system and its specifics; determining the most likely place for embedding software bugs and conditions for their initialization.

Aim. The presented study aims to develop the methodology for assessing the quality of management of organizational transformation processes. Tasks. To achieve the set aim, the authors solve the following problems: determine the essence and content of socio-economic transformation, formulate quality assurance principles for the management of transformation processes, draw attention to the problem of selecting a unified quality criterion for the management of organizational transformation processes. Methods. This study uses general scientific methods of cognition, including analysis and synthesis. It also applies a systems approach to identify the major problems of assessing the quality of management of transformation processes, including the problem of selecting a unified quality criterion for the management of transformation processes and formulating the principles of ensuring the quality of management of transformation processes. Results. The global problem of managing transformation processes in the economic system consists in the complexity of the managed processes, which increases due to the multidimensionality, mutual influence, and the resulting uncertainty of interactions between the elements of the system. It is concluded that the methodology for assessing the quality of management of transformation processes is based on the principle of integrating separate measures to improve the quality of management of system elements into a single system of management actions and the principle of ensuring that management actions are primarily aimed at preventing possible negative consequences of the transformation of economic systems, i.e. reducing the potential impact of unfavorable events and their consequences. To assess the effectiveness of targeted management actions and productive actions aimed at organizing, controlling, and guiding the transformation process, the authors actualize the problem of selecting an adequate quality criterion for the management of transformation processes in economic systems and put forward a hypothesis about a possible unified criterion of management quality. Conclusions. The principle of integrating separate measures to improve the quality of management of system elements and the principle of ensuring that management actions are aimed at preventing possible negative consequences lie at the core of the methodology for assessing the quality of management of transformation processes in economic systems. The quality assessment methodology should be developed in the direction of finding a unified quality criterion for managing transformation processes in economic systems.
