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.

Modeling and Investigating Dynamics of the Electric Drive of Excavating Machines Swing With the Use of the Combined Optimal Control System 000_3.pdf

Improving quality of the automated electric drive is one of the most efficient and cost-effective ways to improve reliability and durability and to reduce down time in repairing mining complexes. currently in Russia, the excavator park has tens of thousands of machines, about 80% of them are exhausted that leads to the need of repairing works. The rotary mechanism electric drive ring gear repair cost is calculated to be 30-40% of the total excavator cost. Optimizing the rotation drive control reduces the dynamic load of a ring gear. Reducing the dynamic load is carried out with the electrical part of the drive that improves reliability and durability of the system. Therefore, the creation of automated electric drive control systems requires the use of mathematical models. The authors consider the rotary electric drive with the highest number of failures in mechanical and electrical parts of the excavator, with a combined optimal control system representing the voltage inner circuit and the optimal regulating device constructed analytically with the highest number of the anchor chain current, engine speed, elastic time, and speed of the second mass located in the forward channel of the control system. In order to investigate the drive, the simulation model was created in MATLAB program with the use of simulink package.

The Software Project Management System Based on the Ontology Approach 000_11.pdf

In information system designing process, one of the most important artefacts of project activities is a set of UML-diagrams. In order to ensure development continuity and organization of interaction between the analysts and programmers, the structure of the domain concepts should be provided. storage and processing of domain data and knowledge can be presented optimally in the OWL ontology format. The article describes a tool that allows automated integration of the UML-diagrams and OWL-ontologies. project UML-diagrams are translated into a XMI-format. After that, the ontology is constructed on the basis of the diagrams, which is available for extension by the specialist in ontological engineering. The ontology can be extended by the introduction of rules limiting the opportunities for building UML-diagrams and, as a consequence, for a software product in accordance with the domain. The main advantage of the ontological approach in the management of software projects is checking the consistency of ontology and receiving the associated UML-diagrams as a result. such checks should be carried out when changing the UML- diagrams or the domain ontology that provides consistent state of a system during the software product life cycle. On the basis of the obtained ontology, new software compatible with the already existing ones can be designed. General ontological base of the software can help to minimize costs of integration of the projects as well as individual modules. The article contains an experiment of translating UML-diagrams from open source projects (github) to the OWL-ontology as well as the analysis of the frequency of the use of class diagrams elements. Moreover, the article presents the results of checking the consistency of the ontologies generated and offers the further ways of this direction development. This article is intended for IT professionals and experts in ontological modeling.

Personalized Learning Maintenance in Project Organizations on the Basis of Kolb’s Experimental Learning Model 000_11.pdf

The article is devoted to the research of ability to apply a cyclic four-step empirical model of a learning process and digestion of new information (Experimental Learning Model) proposed by David A. Kolb and his colleagues from Case Western Reserve University for usage in project organizations. Kolb’s cyclic model is based on “learning through reflection on doing”. The education process consists of iterative steps of “doing” and “reasoning” because of impossibility of effective education only with learning theory and attending lections. But education process without reasoning, analysis, and summarizing cannot be found as effective too. The article proposes the method of creating additional conditions encouraging self-education of designers with fixation, analysis, generalization, and re-use of designing experience in project organizations. The solutions proposed in the article are realized and checked in the question-answering instrumental-modelling environment WIQA (Working In Questions and Answers). In the environment, designing experience (precedents) is presented in the form of question-answering protocols.

Optimization of the Functional Structure of Airborne Hardware Complexes 000_12.pdf

The article shows that it is unnecessary to distribute functions on the basis of their belongings to one of the air vehicle (AV) level in order to take advantages of the integrated modular avionics (IMA) architecture in constructing the airborne hardware complexes (AHC). The method of construction and optimization of the functional structure of AV AHC on the basis of constructing a product functions tree is considered. The basic principles of constructing function groups optimized for implementation on a hardware platform with the desired characteristics are formulated. The authors developed a notion of indirect function realization and described its main advantages and disadvantages. Also, a product functions tree describing algorithm was proposed and outlined. The recursive action algorithm was given by the example of forming one group of functions. The method for improving the load on a hardware unit with its lack of load after the process of forming a group of functions was proposed.

Conceptual Algorithmic Programming and Modeling in the Design and Manufacture of Aircrafts Piping Systems 000_12.pdf

One of the important criteria of a competitiveness of an aviation industry is the cycle time of a production preparation and manufacturing. This criterion is integrally evaluated under conditions of a multiproduct manufacturing when parts and assemblies of various functional purposes may have complex shapes and high demands on quality. A significant contribution to the integral evaluation makes the preparation of production and manufacturing the pipeline systems of the aircraft. The article analyzes the life cycle of the aircraft piping systems at the stage of the technological preparation of production and manufacturing, revealed its shortcomings and features. Among the shortcomings, the authors highlight the long duration and high cost of correcting the errors committed engineering services at the stage of the technological preparation of production (TPP). In order to eliminate these shortcomings, the authors suggest the use of conceptual and algorithmic programming and modeling the activities of engineers to reduce the number of errors that occur due to the human factor at the stage of the TTP, as well as for accumulating and utilizing the experience, the use of which prevents errors. The authors have developed the way of working based on using a system of accumulating the experience at the stage of creating the technological process (TP) and the technical statement (TS) for the technological equipment (TE). The presented study also describes an example of the developing the TS for the design of the TE and an example of the formation of the TS for the development of numerical control programs with the use of the toolkit WIQA.

Intelligent Agent System for Analyzing Design Workflow Models 000_5.pdf

Business process and workflows of project organization represent diagrams as Buisness Process Model Language (BPML), Unified Model Language (UML), Architecture of Integrated Information Systems (ARIS), Integration Definition Metodology (IDEF0 и IDEF3), which may contain errors made by a designer. In order to check that errors we developed a new grammar (called RVM-grammar) that allows us to increase quality of business process management and workflow systems by 20% oppositely with a reserved graph grammar, a positional grammar, and a relational grammar. Thus, we propose an intelligent agent system based on RVM-grammar to analyze business-process models for manufacturing. The system has linear time in order to facilitate the automatically identification of a variety of syntax and semantical errors in workflow models, which enables the analysis of four additional types of errors. In order to consider the distributed dynamic character of business processes, the authors proposed a new intelligent agent system based on the RVM-grammar and analyzing models of business processes with line timetable conformity that extends evaluation precision of syntax and semantic errors in the models of design work flows.

Modeling and Researching the Technique of Thermal Protection of Turbomachines Blades With the Use of Gas-dynamic Temperature Stratification 000_12.pdf

Raising the initial temperature and pressure of the working fluid is one of the simplest and most effective ways of improving fuel efficiency and reducing metal consumption of turbines. Traditional technology of turbine blades production is quite cost and time consuming in production. Therefore, their creation requires the use of mathematical models which serve as a tool for analysis, improvement and selecting the most promising solutions of the refrigeration and increase of the prediction accuracy at the design stage of their effectiveness. Mathematical modeling of the thermal state is widely used in the creation of modern gas turbines [1]. An important objective is the numerical simulation of the spatial flow of the heat transfer in subsonic and transonic lattices. In order to create effective ways of thermal protection, it is necessary to know the distribution of nonstationary temperature fields on the surface and in the body of the scapula. For this purpose, the heat flows from the gas to the blades must be accurately determined taking into account the impact of the mode of flow, thermals, pressure gradient, and other factors [2]. In the paper, the proposed mathematical model and method of numerical investigation of the thermal state of blades of turbomachines streamlined by a supersonic dispersed flow with regard to the phenomenon of gas-dynamic temperature stratification was proposed. With the aim to increase the accuracy of the settlement prediction of the thermal state of blades due to obtaining reliable data as well as improve the efficiency of cooling systems to increase the service life of the blades, the authors have developed the program-informational complex which will take into account the results of studies of gas-dynamic processes in high- speed, disperse flows including the phenomenon of gas-dynamic temperature stratification carried out at the Department of Heat Power Engineering at Ulyanovsk State Technical University.

Representing Design Process By Generalizing Elementary Operations to Semantic Unit Level 000_11.pdf

The design process can be represented by the system of project procedures described in the IDEFx methodology. That allows to decompose it into design stages. Design stage is a sequence of design solution formation actions. Such sequence consists of project operations or procedures and has completeness in terms of getting an object or its fragment with real semantic content (physical meaning). Each stage is strictly defined in terms of either its execution order or the input and output data that makes it impossible to change them and preserve the overall structure correctness of the design solution formation. The authors research the model of project activity processes representation with the use of the introduced concept of the design stage as a semantic unit and Open CASCADE Technology. The researches examine a lot of design conditions and limitations. On the basis of such conditions and limitations, with the use of Open CASCADE Libraries, the system of project procedures was developed. The software implementation of these procedures can provide the modifiability of project stages. Therefore, the representation of design process allows to accumulate, generalize and modify the process of design solution formation preserving the completeness of both the process and design solution.

Pseudocode Programmable Graphics Tools in Automated Systems Designing 39_11.pdf

The article presents the tools for the pseudocode programmable graphics designed for support of automated system engineering at a conceptual stage. The particularity of the approach offered is defined by mapping «block and line» diagrams into a semantic memory of question-answer type. The structure of memory cells and capability of control of cell attributes and values ascribe the semantics, with which programmable actions are liable to occur, to elements of diagrams. The specific diagram image can be converted to a pseudocode program description that can be modified the same way as a source programme code. In addition, the pseudocode diagram presentation can be used for its visualization in the special graphics editor field. Furthermore, mapping the diagram onto its pseudocode presentation offers the opportunity for useful conversions of diagrams that contributes to add model control mechanisms to the design process.

Error Estimation of Thermal Conditions of Measurement Trancdusers With Differential Connection of Sensors 39_13.pdf

The main sources of errors of transducers with sensors differential connections caused by the distinction of thermal conditions of the sensing elements work are considered. Expressions for the distinction of sensors temperature in static and dynamic modes of operation caused by both the distinction of sensors parameters heat and the power dissipated by sensors are obtained. It is shown that instant at grading of the converter with various thermal time constants of sensors the thermal nature error reaches a maximum at a particular instant depending on the relation of thermal time constants. The thermal nature error can also significantly exceed the error in steady conditions.Errors of the differential photodiode are estimated on the basis of obtained expressions, and it is shown that the error of thermal conditions has multiplicative character and depends on the sizes of a light spot. For converters of bridge type the zero temperature drift is proportional to a difference of sensing devices thermal resistance. The more the total thermal resistance of sensors is the more, the more the size of temperature imbalance is.

Structural Design of Configured Patterns of Avionics Parts 38_13.pdf

The paper presents a set of means for structural designing the configured patterns of avionics parts. The specificity of the offered approach to designing this kind of an equipment is defined with the use of means of conceptual experimenting. Such type of experimenting suggests a reflection of the life cycle of any pattern to a semantic memory of the question-answer type. The structure and attributes of the semantic memory cells are focused on coding of models of questions and answers from the viewpoint of their use in solving the creative tasks. In such modeling, any conceptual experiment is conducted as automated mental experiment the structure and content of which are operatively used in designing of patterns.Configured patterns as a specialized equipment for manufacturing and checking of avionics parts have a set of features the main of which are the following: complicated geometrical forms, small rigidity, greater scales, strict requirements to accuracy of manufacturing. Moreover, in the creation of each pattern, it should repeat not only the geometrical forms of the corresponding detail, but needed utility forms should be included to the pattern also. Such additional components of the patterns are oriented on conditions of their use, for example, in assembly operations with other parts. Necessity to take into account the diverse points of view on a pattern leads to creative tasks, which had better to solve preliminary (before making a pattern) on models, by experimenting with their decisions. The decisions that are offered in the paper are realized and checked up in the toolkit WIQA (Working In Questions and Answers) the environment of which supports conceptual modeling and conceptual programming. For designing the configured patterns, cartographical modeling of the structure and specifications of patterns, and also pseudo-code programming of their laser processing are included in WIQA functions. Inclusion in the life cycle of designing the patterns the opportunities of experimenting with their conceptual models leads to increasing the automation degree of designing and quality of its results, reducing the technological time of pattern production. The use of experimenting also promotes the prevention of mistakes and detection of mistakes, and it facilitates the porting of numerical control programs to other CNC laser cutting machine tools.
