The article discusses the ways to improve the safety and efficiency of a destruction complex for organophosphorus agents using development of applied mathematical methods for increasing the reliability and survivability of TPACS of a chemical weapon destruction facility when the hazard level is normal. A management problem is formalized. The problem of optimal control is formulated as a maximization problem. The problem of industrial complex operational management is formulated as a linear programming problem. The objective function of this problem is a linear function, which determines the maximum possible mass of toxic substances that is destroyed in one cycle. The coefficients of a linear function are the price of products and energy flows. Tolerance range of regime parameters of technological operations (capacity balance equation, material flows tolerances, load range) define the scope of restrictions for the objective function. The authors developed a method of determining the intervals of linear model input variables, which do not lead to a significant deviation from the found optimum and at the same time provide stability of the optimal solution when model parameters change; such intervals which indirectly contribute to the survivability of the technological system.

Based on the fact that modern simulators have a hierarchical (modular) structure of their analogue device, the authors have developed a method, which helps to determine the quantitative assessment of the simulation modeling adequacy in the simulator for each hierarchical level as its simulation results become closer to reality. This method eliminates the drawbacks of the method for assessing the simulator adequacy as a “black box”. This is its advantage. However, it has a disadvantage: forming distinct methodological errors. The errors appear during the decomposition of object’s functionals and model in Taylor series and limitations in the use of their members. It is obvious that this error can be detected by comparing the estimates of the adequacy, which are received using the first and the second methods. In the future, this identified methodological error can be taken into account when using confirmed functionals for new statistics. In this case, changes in the conditions of using radioelectronic facilities there is no need to obtain additional statistics. When upgrading individual subsystems of radioelectronic facilities, additional statistical data only from these subsystems is required. However, to ensure correct indication of the concomitant conflict feature in the process of testing and certification of simulators, it is advisable (if possible) to confirm it using the method of simulation modeling adequacy assessment in simulators by their information field.

The development of new types of light airplanes requires justification for passenger and weight-lifting capacities. The fundamental works [2] describe crucial problems of aircraft development for various purposes and methods of their solutions. The problems also concern the issues of general design of airplanes’ particular parts. The article pays attention to finding a solution for automation of the design objective: the effective algorithm of modified cluster data analysis for passenger air travel was developed and software-implemented. In short, based on the literature review, the authors explain the necessity of designing a local airplane with passenger capacity up to nineteen people. The development of an airplane for a specific airline operation takes into account the following parameters: transit range, the amount of passengers and weight of commercial cargo. In case of using cluster analysis classic approaches (K-means or K-medians with a finite number of clusters), in each cluster there will be airline operations exceeding aircraft capabilities with cluster specifications. Moreover, each airline operation represents a point in a three-dimensional space, each axis has a different dimension (kilometres, the amount of passengers, kilograms). Therefore, the problem of measuring the distance in this kind of a dimension arises: it is impossible to select the effective metric in such a dimension. That's why instead of the above-mentioned classic approach the authors used the original method of changing from three-dimensional to one-dimensional space for cluster analysis. It allows using a general Euclidean metric. The criteria of stopping the algorithm is offered and justified. The actual data of 1017 airline operations was processed. The acquired results can be used by aircraft designers and engineers working on aircraft concepts.

24. Optimization for the detection process of new space object orbits by a parallel calculating of possible orbits [№3 за 2015 год]

Observation and cataloging of small debris objects in near–Earth space requires the improvement of the methods and algorithms for obtaining and processing information to improve the efficiency of the optical means. One of the approaches for operative detection of uncatalogued space debris objects orbits has been tested and used successfully in Russian optical observation ground facilities. However, much time is spent on the operation of the exhaustive search of short series of measurements (tracks) and the choice of three series separated in time, presumably belonging to the same object debris and used for the subsequent construction of a possible initial orbit. The article considers the issue of reducing tracks exhaustive search using preliminary analysis of the measurements by a priori constructing the boundaries of possible orbits parameters’ changes. Computational experiments within the research of this application problem are aimed at reducing the average processing speed of one track by increasing the accuracy of estimation. The processing speed of one track is naturally limited since the construction of the possible orbits parameter estimates for each track should not greatly affect the time of the overall measurement processing cycle as part of a trajectory measurements general processing program. The decrease in the average processing speed of one track and the simultaneous increasing the accuracy of estimates is possible with a parallel operation of the program. So, in order to optimize the program for detecting and determining the orbits of new space objects it is proposed to use a parallel algorithm for constructing the boundaries of the possible orbits changes for selection of allowable triples of tracks which have nonempty intersection. The algorithm is implemented in T++ for a T-system with an open architecture (OpenTS).

Regular introduction of innovations in production processes and changing a stock list to match market requirements is a necessary condition to survive in the competition. To account the impact of risks and ensure implementation of innovative development plans it is suggested to use so-called -tasks, which involve a probabilistic assessment of the control object mathematical model feasibility constraints (“soft limits”). The authors propose to replace probabilistic values by the intervals of their possible change for convenient using methods of finding a solution and apply interval-guaranteed optimal control. The article describes the nature and variations of -tasks vectors and matrices components, which are right-hand sides of innovative development model constraints. The paper also considers the algorithms of searching for external and internal problem solutions for a two-model problem formulation of the interval-guaranteed optimal management of innovative development. They take into account the variation ranges of input variables and feasible regions. Enterprise management information systems help to automate evaluating the requirements and external environment conditions, assessing the current status of production processes and resources of the enterprise, running its operation, setting goals and forming an innovative development plan considering risks, updating the goals. These information systems are suggested to call automated control systems of enterprise innovative development (ACSEID). The article presents a functional model of a risk management process and updating development plans. It also describes an information model and database entity, which implement interval-guaranteed management of innovative development. The use of ACSEID will ensure the implementation of the enterprise innovative development plan if the uncertain parameters are within the specified ranges of their change.

The paper suggests implementing a new concept for 6 Party Logistics (6PL) by analogy with 5PL provider. It is based on the technology of management by conditions in multi-actor integrated information environment. The article de-scribes the results of the analysis of modern levels of logistics services and their implementation features in the context of modern information and communication technologies that are used to build the shared information space and virtual interac-tion of logistics supply chain members. A 6PL provider concept is proposed. On the 6PL level the logistics supply chain members interaction conditions in integrated information space are formed. These conditions are presented as contract agreements that reflect the cases of permanent cooperation between the actors. In contrast to 5PL provider that does not change the interaction conditions and makes no limitation of actors’ decision-making, the 6PL provider can develop new contract agreements that determine long-term cooperation or competition between the actors. The paper provides a list of software components that implement a concept of 6PL provider. The 6PL software platform can be introduced as a part of logistics supply chain resources management system, a manufacturing scheduling sys-tem, Web portals, an enterprise resource planning system, business processes simulation and decision-making support sys-tems.

Carrying out a scientific research in different areas requires huge amounts of computing power. Moreo-ver, computationally demanding tasks are assumed to have access to powerful servers and computing clusters and are expected to support handling big data sets. On the other hand, mobile devices have become increasingly powerful, that makes it possible to employ them in large-scale data processing, particularly, for volunteer computing like BOINC and Folding@home. Nevertheless, despite the advances in hardware, it is important to improve computational algorithms taking into account the following constraints which are determined by mobile devices characteristics: long response time, limited memory and battery life. The main purpose of this research is to create the algorithms to estimate Fourier coefficients according to these minimal requirements. To attain the aim, we employed connection coefficients method to work out specific relations for continuous Laguerre functions. In comparison with the corresponding recurrence re-lations, which entail an enormous computational cost, the proposed analytical relations require less computational re-sources to produce results (in particular, time and space). To support the theoretical results, we conducted a series of computational experiments using MATLAB Profiler. The findings of this research present the software implementa-tion of Fourier coefficients estimation to operate with limited computational resources and the results of the mobile application tested on a device. Based on these tests, we analysed the elapsed running time to process big data sets vary-ing the volume of data and the number of Fourier coefficients.

Plastic cards (credit, debit, and others) are the keepers of personal information. The structure of information recording and the process of applying information on these cards is becoming more and more complex with time. Card personalization process involves the use of complex equipment, and hardware-software complexes. There is a variety of desktop equipment for personaliza-tion of small quantities of plastic cards. High performance machines and firmware complexes for high volumes of cards personaliza-tion are also produced. Card personalization can be controlled by software from different vendors. Various additional technological processes can be performed at the same time when personalization is being done. Different types of software are required to perform these operations. The article considers the software for plastic cards personalization systems including smart cards personalization systems, personalization center management software, software for card quality control systems, issued cards packaging and sorting management software, PIN envelopes personalization software. The paper contains a general description of work stages and interac-tion of processes associated with personalization of plastic cards. Particular attention is paid to the domestic import-substituting software. Where it is possible and appropriate, the article refers to relevant electronic resources, which can be accessed via the Inter-net.

The article discusses specialized software for computer-aided design of nozzle layout in secondary cooling sec-tions of continuous casting machine. The main purpose of the system is calculation of nozzle optimal positions in each space between rollers with respect to predefined optimization criterion for the thermal state of the slab. The system is logically di-vided into three subsystems: a subsystem for managing input data, a subsystem for simulation and optimization, a subsystem for storage and visualization of output data. System decomposition into program modules is given based on the logical struc-ture. The core of the system is the simulation and optimization module, which implements numerical search of nozzle opti-mal positions on the basis of iterative simulation of the thermal state of the slab when using given nozzle layout and repeated correction of that layout. Apart from the core, the system contains modules for filling and editing input data, data serialization and data visualization. The system is implemented in an object-oriented paradigm using Java language. Netbeans Platform is used as a base for building user interface of the system. The article presents a brief description of system user interface as well as an example of applying the system for calculating nozzle optimal layout for an existing caster.
