A practical approach for requirements systematization

The author: Simkin A. V.
This article describes an approach to requirements for integrated information system systematization. The approach proposed is the framework that can be used for the technical requirements formalization aiming to classification and definition of the relationship between the different types of requirements.

A system for automatic customers’ opinion mining

The author: Yatsko V.
which was created on a request from an overseas firm, processes chats, blogs, and forums to provide as output generalized negative and positive scores as well as specific subjectivity terms associated with the product’s name given in user’s query. The system is based on the highly structured ontology and linear grammar. The ontology consists of syntactic and semantic terms ad their subcategories, groups and classes. Semantic terms are those ones expressing subjectivity and having either positive or negative semantic orientation. Syntactic terms do not express subjectivity but can modify the intensity of polarity of semantic terms. The relation between semantic and syntactic terms is defined as a binary relation and groups with symmetric, asymmetric, and inverse relations between syntactic and semantic terms are distinguished. Semantic terms are assigned scores from 1 (–1) to 9 (–9). The paper suggests differentiating between formal and linguistic ontologies. Linear grammar comprises rules that allow mapping ontology terms onto the names of products and generate phrases with semantic and syntactic terms. The overall system’s efficiency measured in terms of recall and precision of information retrieval achieves 86%.

Accounting non-stationary in the temporal-logical model of the project

The article analyzes non-stationary arising in the process of project management at the industrial enterprises and their effect on the project structure. The method which provides accounting of non-stationary in the project temporal-logical model structure is presented. An example of the practical use of this method is given.

Analysis of IT effect model based on a structural approach

The article analyzes the structure of the effect of using automated management systems. The analysis is performed on a structural approach. This article contains two parts. In the first one lists a number of problems that are universal character and faced researchers in the performance evaluation of the effectiveness. For each problem there is a brief description. The following is a brief overview of the most common approaches and methods by which the estimate of effectiveness. Their number and methodological breadth requires additional approaches to select the right tools to measure performance. In the second part of this article provides examples of the structure of the IT effect that can be detected in the works of different researchers. For notes, other researchers of this domain does not accentuate focus the structure of the IT effect. Then describes the author’s vision structure of the IT effect and briefly describes possible approaches to evaluating the effectiveness of the implementation of MIS in accordance with the proposed structure. In conclusion, the authors again emphasize the special role of the structure IT effects, it plays in the effectiveness evaluation.

Comparative analysis sites of searching wholesale suppliers according to the criterion of functional completeness

The author: Orlova N.
Methods of analysis by the criterion of functional completeness long been successfully applied in various domains. However, never before this technology is not used for comparison sites of searching for wholesale suppliers. These investigations have produced unique results and make evidencebased conclusions very useful for market participants of wholesale deliveries. The solution to the problem of selecting the best from the variety of Internet sites search wholesale suppliers is a difficult task. In article on the basis of real evidence about the realized functional operations analysis and the choice of optimal business solutions. Compiled a list of the functions available on the market sites search wholesale suppliers. Systematic information on the composition and functional completeness of existing sites search wholesale suppliers and their projects. It is possible to quantify the degree of conformity of a particular system requirements to functional completeness. Ranked sites search wholesale suppliers according to the criterion of functional completeness. Excluded from the scope of software products, which are not implemented the required functions. There are groups of software systems, such as ongoing functions. Provided support to select the desired component sites search wholesale suppliers or its design and development. Studying of experience of effective achievement of the purposes of research at minimum cost will definitely help it professionals to optimize its activity in the sphere of analysis of complex systems.

Computer-aided analysis and optimization of structural and parametrical reliability of complex gas supply pipeline systems

The author: Meshalkin V. P.
The scientific and technical basis of the computer-aided analysis, optimization methods and techniques to ensure the structural and parametrical reliability of energy and resource saving Complex Gas Supply Pipeline Systems (CGSPS) are generalized and developed. The methodology for support and optimizing the performance reliability of CGSPS is presented. Оriginal techniques for engineering and technological failure analysis of facilities and complex gas pipelines, forcasting, reliability diagnostics and troubleshooting the causes of CGSPS are developed. New engineering techniques to ensure the reliability and safety of CGSPS systems are proposed. The technique for construction and practical application of the original topological (graph) models of gas supply pipeline systems reliability is briefly stated. On the basis of these models original methods of reliability factors calculating, including a qualitative analysis method of «the reliability of gas supply pipeline system topology» and decomposition methods of reliability multi-criteria optimization for CGSPS, are developed. Special program complexes for calculation and optimization of reliability, security risk management, integrated logistic support of gas pipelines and facilities of CGSPS, environmental monitoring and CGSPS impact assessment on the environment are developed.

Designing extreme experiments based on simulation models

The author: Emelyanov A.
An extreme experiment design methods based both on fullscale models and physical and mathematical models of technological, physical and chemical processes are widely used in industrial environment. However, they are rarely used by mathematical economists while formulating experiments based on economic processes simulations. The reason for it is a time passed since the simulation methodology has been adapted to economics which is too small compared to other application areas.

Development of a computer expert system business planning

The article discusses the problem of optimizing the implementation of the business planning process, corresponding with specific technical and economic conditions and constraints. To solve this problem, we propose to use the intellectual information decision support system that allows to optimize the formation of a specific business plan. Development and creation of such a system is based on network models and methods of economic-mathematical modeling and computer expert systems technology. The results obtained may serve as a basis for the development of appropriate systems of intellectual support management decision making in the implementation of the business planning process.
