The calculation model of hardware and software system production period designed by developing companies65_9.pdf

It is relevant for a developer of hardware and software systems to assess the duration of development in advance and determine the main factors influencing on its success. Bulk production or bulk production with little changes can be assessed based on the experience. However, when making preliminary assessment, some factors that had not a great effect before may not be considered. The article describes an approach to calculate the duration of hardware and software system development based on analogues, statistics and factors effecting the production. At the same time, it should be noted this method provides only a preliminary assessment and its usage requires additional s.

Duration of production plan development, neural net, small-scale manufacturing, design production, machinery, production capacity, operation flow statistics.

The extraction of terms consisting of several words from texts in natural languages using the syntactic patterns65_12.pdf

Two problems arise when extracting terms consisting of several words using linguistic methods of text analysis: 1. A linguist has no skills in software systems development, however he (she) is required to present his (her) knowledge in the form of software system fragments or constructions in a formal language. 2. Most software developers are not qualified enough in linguistics. This problem creates a semantic gap between the methods of linguistic analysis of texts and their software implementation. The article presents an approach to extract the terms consisting of several words based on syntactic patterns tailored for a linguist. The proposed approach does not require additional skills and usage of various languages to describe syntactic patterns by a linguist.
The prototype of the software system was developed. The software system allows describing syntactic patterns without having knowledge of a formal language. Moreover, as against the analogs the developed system is capable to use syntactic patterns in external systems for text analysis. The server of the prototype has an interface to make the syntactic patterns.

Natural language processing, parse tree, syntactic patterns, terms consisting of several words.

Automated control of the software prototype code review based on the question-answering protocols for requirement analysis63_13.pdf

The paper describes the architecture of software tools for automating the management of code review of software prototypes of design solutions that allow to obtain such effects as ensuring interactive interaction between the designer and an expert performing code review, as well as reducing the expert’s time spent on commenting the code by selecting a comment from the list prepared in advance for each requirement from the requirements obtained during the analysis. The tools being developed consist of three main parts. The first part presents requirements in a question-and-answer format including standard comments to be inserted into the prototype code in case of non-compliance with these requirements. The second one is a relational database, which is designed to store the source codes of prototypes aimed at inspection and passed it with expert comments. The third one is a Web-application that allows the designer to send prototype codes for review and see the results of the inspection, and an expert to provide viewing and editing of the prototype source code with the insertion of both standard, pre-prepared comments, and written in free form.

Prototyping, code review, requirements analysis, question-answer models.

Models and designing methods for the dynamically reconfigurable group control system for mobile robots63_14.pdf

High adaptability is an important requirement for the control system over a group of mobile robots operating in a nondeterministic changing environment. The group control system must ensure that the group task is completed when the structure of the group or the environment changes. Such adaptability can be achieved through dynamic reconfiguration of the control system. The article discusses the mathematical models of a dynamically reconfigurable system from the standpoint of computer-aided design. A review of mathematical models of variable structure system, reconfigurable control systems and their design methods is presented. The paper deals with set-theoretic, analytical, discrete-event models of variable structure systems and methodologies of designing reconfigurable systems. It is shown that the existing design methods do not fully provide the required adaptability of designed group control system. The paper compares the group control system and the reconfigurable multiprocessor computing system and shows how to increase adaptability and autonomy of designed control system using principles of reconfigurable computing systems designing.

Program development for designing simulators of advanced flight electronic support systems62_14.pdf

The main radio equipment used by aviation specialists are communication, radar and radio navigation systems. Training of students in these areas is a complex task that requires significant efforts of lecturer. The article proposes a concept of simulator designing that are supposed to be adopted in the educational process of civil aviation institutions based on hybrid approach to the virtual simulators designing. Such concept was applied in the development of methodology for designing of simulators for flight electronic support, which involves solving the problem of selective structural synthesis. The problem of selective structural synthesis of design solutions is described using a morphological tree and implies finding the graph edge that ensures meeting a set of rules with the constraints specified in the process of specification drawing up, which is replenished by the developer-user. Due to random nature, the structural optimization method implies a sequential search for possible options. A computer-aided system of simulator designing for flight electronic support systems was developed based on the methodology. The development of a computer-aided system of simulator designing for radio communications, radar and navigation equipment makes it possible to provide effective training of future pilots and air traffic control officers.

The ensemble principle and analytical model of project workflow organization61_14.pdf

The purpose of the author’s fundamental research is to increase the efficiency of processing business processes in automated systems (AS) in the basis of graphic languages by reducing the time spent on their development and processing. The goal is also to improve the success of the processing of workflow diagrammatic models. Moreover, success is understood as meeting the requirements for resource constraints, including functionality, financial component and deadlines. Also, the goal includes improving the quality of diagrammatic models by controlling denotative and significative semantic errors. The business process itself is presented in the form of a diagrammatic workflow model, and process processing refers to the analysis, control, transformation and interpretation of workflow diagrammatic models. The paper contains an analysis of existing approaches to automating the design of workflows in a large design organization. Descriptions of the development of the theoretical foundations for the processing of diagrammatic models of workflows are proposed in the form of a new principle of organizing the flows of design work in the basis of graphic languages – “Ensemble”, a new analytical model of organizing the flows of design work, taking into account orchestration, choreography. The developed principle and model are integrated into the methodology of the structural-semantic approach. A computational experiment based on the developed model is described, which represents the workflows of design work in the design preparation of production and technological preparation of production. This article is one of the follow-up works on the methodology for processing design workflows in the basis of graphic languages.

Using a role-based approach and genetic optimization for vlan design in large critical infrastructures60_9.pdf

The article considers a new approach to the formation of access control schemes in the design of virtual local area networks (VLANs) in large critical infrastructures, based on the use of an improved genetic algorithm, the introduction of multiple roles for network nodes and the accounting of mapping between a set of network nodes and a set of roles. The problem statement is justified as the optimization of access control schemes in VLAN according to the criterion of minimum number of virtual subnets taking into account the peculiarities of role approach. The problem being solved is shown to belong to the Boolean matrix factorization problem class, in which the original matrix is decomposed into four ones forming two independent pairs of straight and transposed matrices. Improvements of the genetic algorithm involve multi-chromosome representation of individuals, a new kind of fitness function, and a two-dimensional kind of crossing operation. The experimental evaluation showed a benefit in the speed of the role genetic algorithm at a large task dimension of up to 5 times at a sufficiently high accuracy of finding the optimal solution.

Methodology for developing a subject-oriented language and tools for creating automated management systems for complex organizational and technical systems 60_10.pdf

Modern technologies for industrial development of complex software and hardware systems are based on model-oriented technologies and tools for visual design, modeling and validation. Practical application of these technologies is complicated by both subjective and objective factors due to their flexibility and being hard-to-develop. One of the ways to reduce the impact of these negative factors is to create special-purpose domain-specific languages and tools supporting design of the systems of a specific class and a specific application domain. The article describes methods and tools for creating domain-specific languages and domain specific modeling (DSM) solutions intended to develop computer-aided control systems for complex organizational and technical systems using technologies and tools developed within the scope of the Eclipse Modeling Project. The most complicated and at the same time least worked out issues are those one, related to the identification and concept formulation of application domain of a DSM solution and the selection of an optimal and appropriate set of tools and structures. The conceptual model of the application domain of computer-aided control systems is formed as a task-oriented ontology using Zachman Framework. It is a set of control functions arranged in hierarchical order, which are performed by management bodies under controlled objects to achieve goals using certain algorithms in accordance with specified time, limited resources and other constraints. DSM solutions, made and used to develop computer-aided control systems, will improve their quality and reduce time, taken to designing due to the following facts:– development of requirements for computer-aided control system and its designing is carried out jointly by experts, analysts and programmers using special tools within the application domain;– the resulting requirements and design solutions are validated and verified as per stringent standards, which allows for correct generation and testing of software code;– end-to-end quality control under all system lifecycle artifacts

The creation of the knowledge base of design organization for automating the architecting process of software systems59_10.pdf

This article deals with an approach to automating the architecting process of software systems based on the experience of previous projects. The architecture of the software system is the understanding and presentation of the software system in the form of the architecture description. The architecture description consists of many design artifacts. Design artifacts are formed during the whole life cycle of the system. It is possible to improve the quality and reduce the time of design and implementation stages in the process of developing a new software system based on the experience of previous projects by extracting design experience units from previous projects. The design experience unit is a successful design and architectural solutions used in previous projects. The article describes the logical model of the knowledge base of the design organization that allows storing and searching for design experience units. The knowledge base model also allows link the design experience unit with the project where it was obtained, with the stage of the life cycle model where it was formed, with the concepts of the subject area, and with the design artifact from which it was extracted.

A prototype of a system for searchning and selecting the ‘staffed’ teams of it-professionals based on data from project repositories59_11.pdf

The growth of information technology sphere leads to a serious shortage of qualified personnel. Thus, many companies are changing well-established workflow models, e.g. giving employees the ability to work remotely. That happens due to the opportunity of hiring globally. For companies focused on the development of product solutions, there is a trend of searching for “played” project teams, specialists who have successfully worked together for a long time. However, the search for such teams leaves a definite imprint on the activities of the HR department of the company: it becomes necessary to analyze the activities and technical developments of not individual employees, but of the potential team as a whole. The article describes a prototype of an automated system which main task is to search and select teams of specialists based on data from open source code repositories and related artifacts. The article details: the composition of the system architecture, the selection algorithm for the main project team, identified during the study of the group activity metrics, formulas for calculating the values of the metrics, as well as their application in solving the problem of analyzing the project repository.

An Architectural Approach to the Precedent-oriented Problem Solving in the Designing of Automated Systems 55_6.pdf

The article presents an approach to architectural modeling focused on its use for the development of functional components of an automated system (AS), each of which is associated with the solution of a specific design task. To ensure the independence of the application of the approach from the domain of the AS, its implementation is associated with the creation of the subsystem TASK, which expands the potential of the instrumentally modeling environment OwnWIQA, which serves to solve design tasks in the workplace of a member of the design team. The specificity of the toolkit includes the formation for the solved task its reusable model (model of precedent), which is included in the Experience Base used in the design process of a certain AS or their family. The subsystem TASK was developed in the OwnWIQA as its application using the executable pseudo code language embedded into this toolkit. The constructed version of the subsystem TASK is interpreted by the authors as a prototype, the reprogramming of which will be conducted in C #.

Automation of Workflow Design in an Industrial Enterprise 55_7.pdf

Increasing of the automated workflow synthesis systems efficiency is the fundamental scientific problem of the business process management theory. The problem includes such subtasks as processing in order to reduce the time spent on their development, increasing the success of processing diagram models, namely the implementation of the requirements for resource constraints, functionality, financial component and deadlines, as well as improving the diagram models quality in terms of error control, narrowing the semantic gap between business process analysis and execution.In the article, an approach to the analysis of workflow diagram models on the basis of temporal automatic grammar with linear analysis time is proposed. The approach allows to control and analyze structural-semantic and temporal errors. The results of the research represent that the approach has significant advantages over similar methods of analysis. The effectiveness of this analytical approach is proved by concrete real and relevant examples.

The Coordination of Manufacturing Cycles By the Method of Mutual Penalties 55_8.pdf

The article deals with an algorithm of the product manufacturing cycle coordination implemented in the SAPFORD system when planning the make-to-order production. MES-Systems well-known in the Russian market, which are intended for the machine scheduling calculation and based on branching schemes, are not effective for the plant scheduling in real time. When scheduling design problem solving, author shows that the specific details of the machine scheduling of make-to-order manufacturing allow using the effective methods like task decomposition, co-ordination of the sub-task criteria against each other and with the universal criterion of optimality. The make-to-order manufacturing scheduling task is broken to subtasks of the detail and process distribution through workplaces with preset parameters in a reasonable amount of time. The criterion estimation of the cost-push during delay or abnormal end of the operation is calculated for each operation. The method of the mutual penalties allows to implement the coordination of subtask criteria, whereby details and operations engaged in competition in queue impose to each other penalties like estimation of costs caused by delay. The proposed algorithm provides an effective planning of the make-to-order manufacturing based on a unified machine scheduling with no limits on initial data scope for product range and manufacturing processes. The favourable environment is created for paralleling the problem solving process, which in turn allows to use all the multiprocessor system resources. Author gives examples for problem solving.

Application of Fuzzy Models in the Analysis of Processes in Organizational-technical Systems 51_11.pdf

The article discusses the application of the Fuzzy models for time series analysis. The main aspect of the analysis is the formation of groups of similar processes. For the grouping of processes, they are considered in the form of discrete time series. Traditional methods for clustering time series based on point-by-point clustering, on attributes or models, do not take into account the nature of the behavior of the time series, which ensures the information content and quality of clustering. To solve this problem, a clustering algorithm based on a fuzzy approach, called Fuzzy Behavior Clustering (FBC approach), was proposed. The proposed time series clustering approach considers the behavior of time series at three levels of the hierarchy (at the level of the general tendency, the level of the parameters and at the level of values). The behavior of time series at the level of the main tendency is described by means of linguistic terms. At the heart of the FBC-approach lie a fuzzy representation of time series and an algorithm for a linguistic assessment of the main tendency. The application of the FBC-approach for analyzing and clustering time series of KPI dynamics of IT project developers based on data from the repository is provided.

Fuzzy behavior clustering, fuzzy clustering behavior, combined clustering of time series, the linguistic terms, extraction of fuzzy tendencies of time series.

Technical State Control of Complex Systems Via Fuzzy Model 51_12.pdf

The paper describes the management method of industrial equipment technical condition based on heterogeneous data systematization using a mathematical apparatus of fuzzy sets. The paper presents a fuzzy model for describing (estimating) the object technical state. This model allows a single way to process different types of information about an object and bring it to a unified form. The paper describes physical meaning of universal indicator of the object state - Technical State Index (ITS) in the view of fuzzy sets theory. The parameters dimensionality reducing method is proposed for multicriteria analysis. The problem of objects ordering (ranking) is solved. A fuzzy structural-parametric model for intellectual decision-making support in the technical state control of complex systems (including industrial equipment) consisting of many composite elements with unique parameters is proposed. The algorithm for calculating ITS of complex technical systems is considered. The up-to-date approach described in the paper will allow to apply computer information processing methods for implementation in problem-oriented control systems and decision support systems to increase equipment reliability and management efficiency. The paper presents the results of the proposed method implementation as equipment technical state management information system of gas transportation enterprise. Conclusions are formulated and prospects of further scientific research in this field are reflected.

Matching of Project Alternatives to the Main Aircraft 51_13.pdf

A method for matching design alternatives is proposed, it is based on the consistent application of correlation, factor analysis with the subsequent construction of polynomial models by the least squares method and the Brandon method. A multiparametric approach to the analysis and synthesis of the design solution variant is formulated, based on the formalized process and allowing to realize the uniqueness of the solution for individual elements (on the example of the wing) of the main aircraft, at the stage of the preliminary design. A technique for taking into account the influence of the characteristics of one design alternative on the other and their transfer to calculations at the stage of preliminary design of the main aircraft is proposed. The set of obtained polynomial models is seen as a transition function, on the basis of which it is possible to construct a surrogate model that allows data generation on varieties of smaller dimension to solve non-standard design problems as part of a complex technical system - the main aircraft or its element in the appearance.

Architecture Optimization of Functions of Airborne Equipment Complexes on the Basis of Integral Modular Avionics 000_3.pdf

The article deals with the process of designing of an airborne equipment complex based on integrated modular avionics. For a more complete disclosure of the advantages of the new architecture of the complexes, the authors propose to single out the process of designing the architecture of the product functions in the form of a tree in a separate stage. Taking into account that the design process of the complex is closely connected with the process of assessing its security at all stages, the article shows that the design of the product function architecture should be intermediate between technical analysis and safety analysis and the process of circuit design of the product. That allows to perform a primary assessment of the product fault safety level, formulate requirements for the application of methods in order to increase its reliability and fault safety at the early stages of design. Optimization of the architecture of the product functions also allows to justify the hardware requirements of the complex.

The Automated System of Coding and Classification of Production Objects 000_7.pdf

Increasing efficiency of design and technological training in conditions of multi-nomenclature serial production can be ensured by coding and classification of parts. Therefore, the paper provides theoretical substantiation of classification characteristics of parts and their grouping. A method for coding details is proposed, in accordance with which details are assigned an impersonal code of its design characteristics according to the United Design Documentation System (SUDD) classifier. Technological characteristics of the parts are coded in true values from the drawing. In practice, the technique was implemented when creating a regional data bank about details that contains information on 150 thousand items. The article shows the functional-structural scheme of the automated system for coding and classification (ASCC) of parts, consisting of four subsystems: coding of parts, generalization of parts characteristics, selection of design solutions, output of technical documentation. At industrial enterprises, ASCC allows to significantly increase the labor productivity of designers and technologists in the preparation of production and the quality of the design decisions they make.

The Application of Design Ontologies in Technological Preparation of Aircraft Production 000_7.pdf

Currently, the use of ontologies in the aviation industry has not yet been properly developed but the analysis of domestic and foreign authors’ works shows the positive dynamics of the intelligent support systems implementation in this area. The article is devoted to the creation of tools for ontological support of works at the stage of technological preparation of aircraft production on the basis of the authoritative approach allowing to carry out experiments with semantic models of diversified production tools at the stage of technical specification and to make decisions on the appearance of the support system artifacts constructive on the basis of the obtained results. Due to the fact that the design process is carried out with the use of a vocabulary and controlled semantics, the proposed means will allow to ensure effective interaction dialogue "designer -system" (in this case, the design is carried out using professional natural language) and also to accumulate, process, and store design and construction knowledge in the form of experienced units.

Structural and Logical Design Solution Class Generalization With the Use of Design Procedures Representation Adapted Functionally 000_9.pdf

Design of modern products relating to different subject areas and consisting of a large number of components differs by the presence of the technical requirements to the entire product without separate requirements to its components. The design activity results include complete design documentation and product assembly 3D-model. The process of assembly 3D-model formation includes adding 3D-models of components and establishing conjugations between them. In order to construct, correct, and maintain (update or modify) a 3D-assembly, rebuilding should be provided. Typically, the process is carried out through manually handling of parts parameters and conjugations. That requires additional time and labor expenses. The authors propose the solution of the problem in establishing the structural and logical relationships between the components of the assembly 3D-model on the attribute level allowing to link the components and structural objects. Interrelations between the components allow not only to determine their location and link to each other operating with design parameter values but also to modify the design solution without violating its integrity that is not ensured by any modern cAD-system.
