Authors explore issue of applicability of the methodology of building diagnostic software using network formal models in the functional testing of electronic equipment as part of complex technical systems. Using methods of system analysis allows to perform a decomposition of interdependent subsystems and to reveal basic acts of interaction between the control‑verification equipment and the object of diagnosis. Mathematical apparatus of Petri nets should be employed for the formalized description of such acts and determined the cause‑and‑effect relations in the diagnosed complex system`s processes. Network models properties studying (such as safety and accomplishment of the final positions) allows us to move to the test object`s algorithm`s developing. The article presents an approach of a formalized description for basic acts of interaction between the diagnosis system and the object.

Abstract In order to fully exploit the potential of the rapidly progressing digitalisation of technical systems, it is necessary to provide reliable and significant process and condition related data. In this context, solutions are especially aspired to allow a simple integration into the surrounding system and to influence it as little as possible. The main challenges regarding the measurement of process and condition data in the operation and control of technical systems as well as in test environments are identified and presented at the beginning of this article. A promising approach to meet the resulting requirements is the integration of sensory functions into simple standardised machine elements. In order to facilitate the discussion and interdisciplinary development of machine elements with sensory functions, an extension of the existing classification of mechatronic machine elements is introduced and illustrated with examples. The introduced classification takes into account the classification according to Stücheli and Meboldt and is based on a comparison of conventional and mechatronic machine elements on a functional level with regard to the function structure. As a result, the three classes sensor carrying machine elements, sensor integrating machine elements and sensory utilizable machine elements are introduced and subsequently discussed in more detail on the basis of examples. Finally, an outlook is given on the main research areas with regard to the development of mechatronic machine elements. Key aspects include working principles and effects for application in mechatronic machine elements, system analysis with regard to load conditions, power supply of sensor and data processor in the environment of the machine element as well as data processing and signal transmission under typical environmental conditions of mechanical engineering.

A new mathematical model of a general autoimmune disease is presented. Basic information about autoimmune diseases is given and illustrated with examples. The model is developed by using ideas from the kinetic theory describing individuals expressing certain functions. The modeled problem is formulated by ordinary and partial equations involving a variable for a functional state. Numerical results are presented and discussed from a medical view point.

The construction organizations lack adaptive infrastructure. It is required to use more intensively SMART-technologies of design and construction. Purposes of this article: a) the system analysis of categories "competitiveness", "stability", "rating of the company" for the construction organizations; b) to construct and investigate economic and mathematical model of competitiveness of the construction organization; c) to determine parameters of self-organization of construction company; d) to construct an identification algorithm for model. These new tasks also answer the purposes of modern construction business, problems of forecasting of its development. Using methods of the system analysis and modeling, in work three levels of the analysis of construction business are considered: macrolevel (level of the state), mesolevel (level of the region) and microlevel (level of the company). For example, 10 various classes of competitiveness of construction companies are offered. It improves the classification used traditionally. The new economic and mathematical model on the basis of production functions of type of Cobb-Douglas is constructed. The algorithm of its identification on the basis of situational scenarios is also developed. The algorithm finds parameters which will allow to define competitiveness of construction company a priori. The offered research has a development, for example, is possible to use for the forecast of adaptation of the enterprise.

For some time past the careful attention of researches requires the issues of analyzing qualities of test objects and compliance actually received tactical and technical characteristics with specified operational requirements, it is necessary to get the parameters of high-precision trajectory measurements that will enable comparison (deviation) of the real trajectory from the reference trajectory (pattern trajectory); evaluate the operating benefit of the test objects; identify the causes of nonconformities of tactical and technical characteristics to requirements, which can be detected. Today for measuring the trajectory parameters of the test objects using equipment, which operates on different physical principles. It refers also to the electro-optics equipment, in which implemented process of target tracking for the purpose of obtaining on a real time basis initial information, further processing which will allow to calculate highly precise trajectory parameters of test objects. Therefore, the purpose of the article was a justification for composition and tactical and technical characteristics of prospective mobile optoelectronic complex of trajectory measurements. On the basis of the modern analysis of the objects of ground tests, their main characteristics, as well as the tactical and technical characteristics of modern mobile optoelectronic complex of trajectory measurements of domestic and foreign production and taking into account the “General requirements for mobile optoelectronic station of externally - trajectory measurements” from 01 October 2017, the project of composition and the tactical and technical characteristics prospective mobile optoelectronic complex of trajectory measurements was justified. Research design - the theory of probability, system analysis and synthesis of organizational-technical systems, theory efficiency and optimization, simulation of complex technical systems. The main results, obtained in the work:  - composition and the tactical and technical characteristics prospective mobile optoelectronic complex of trajectory measurements were justified; - general requirements to the mobile optoelectronic complex of trajectory measurements were developed; The practical importance lies in the possibility of creating mobile optoelectronic complex of trajectory measurements of domestic production to conduct testing of new and modernized specimens of weapons and military equipment. The study is novel in that it: general requirements to the mobile optoelectronic complex of trajectory measurements were developed; the project of terms of reference for the creation of a mobile optoelectronic complex of trajectory measurements of domestic production was worked out to provide testing of specimens of weapons and military equipment.
