    Application of Java-technologies for simulation in the web
    (Information Systems Technology and its Applications, international conference ISTA'2001, 2001) Kazymyr, Volodymyr; Demshevska, Nataliya
    In this article, the visual Internet-oriented Java-based E-net Simulation System (JESS) is considered. JESS supports all the simulation stages from constructing the models to experimenting with them. The basis of JESS is an object-oriented formal model and a specification language that supports several levels of model description with an E-net specification. The Internet-orientation of the system allows to create models executed on a remote server and makes these models available from any point of the network. This article contains descriptions of the JESS simulation technique and the implementation of its Internet properties.

    Application service provisioning - Current state and partnership strategies
    (Information Systems Technology and its Applications, international conference ISTA'2001, 2001) Kallio, Päivi
    The European Application Service Provisioning (ASP) market is estimated to grow to USD 8.2 billion in 2003. Application Service Providers are companies that provision software applications over the Internet. The ASP will change traditional software businesses by turning software applications from products to services. This study researched the state of the current software business, ASP and the ability of Finnish software companies to gain partners in the international ASP competition based on the situation in November 2000. The current state of ASP business was examined by researching literature and four Finnish software companies that make use or are going to make use of ASP in the future. Because the concept of ASP is new, the amount of previous researches concerning ASP is very limited. The current state of software companies in this research is based on a study made by Forsell and Nukari in 1999 and on an international research of 100 software firms made by Harvard Business School in 1999. In this research it was found out that Finnish ASPs seek value added service and technology partners on the basis of their quality and trustworthiness. The partners co-operate in marketing, support and research. The current ASP market is fast changing, fast growing, immature and uncertain, but the faith in it is very strong. Finnish companies regard finding competent partners difficult because of the still immature market. Technology and security do not prevent the widespread use of ASP. The keys to success in the ASP market are co-operation with qualified partners, specializing in existing strengths, and qualitative and secure software products.

    An approach to dynamic ontology modification in mediator service-oriented information systems
    (Information Systems Technology and its Applications, international conference ISTA'2001, 2001) Keberle, Natalya; Ermolayev, Vadim
    The paper proposes the approach to cope with the maintenance of dynamically changing resource ontologies of autonomously maintained, distributed, heterogeneous, wrapped information resources and their mappings to common mediator IS ontology. The approach intends to do the work in economical way reducing efforts to matching and aligning only modified ontology elements. Proposed is ontology model comprising both descriptive part and the set of modification primitives for each ontology structural element. The set of ontology modification invariants and the corresponding set of modification conflicts resolution rules are formulated for taxonomies. The way to provide IS services for ontology changes monitoring, matching and alignment is outlined.

    CC/PP negotiation of a mobile station in MExE service environment
    (Information Systems Technology and its Applications, international conference ISTA'2001, 2001) Sihvonen, Markus
    MExE (Mobile Execution Environment) is a standardised middleware platform in an MS (mobile station) where to execute 3rd generation applications and services regardless of the operating system. It is one of the 3GPP’s (third generation partnership project) VHE (Virtual Home Environment) toolkits, perhaps the most complex but also the most flexible and diversified one. It enables a dynamic download of applications to an MS at a users’ request. Currently, applications can be written in Java and WML (Wireless mark-up language), later possibly with many other programming languages. CC/PP (Composite Capability / Preference Profile) negotiation normally occurs prior to a download of an application to an MExE capable MS and it is used to define the right version of the requested service or application to that particular MS. Even though the technology is being under development particularly for 3rd generation mobile networks and MSs, it can be also applied to 2nd generation mobile technology. This paper focuses on CC/PP negotiation of the 3rd generation all IP (Internet protocol) MSs. The purpose is to identify problems of the CC/PP negotiation and to propose a solution for the negotiation strategy. At the very beginning, the problem area will be introduced to the reader.

    Design and development issues of retrospective database in complex technological control systems
    (Information Systems Technology and its Applications, international conference ISTA'2001, 2001) Kuklenko, Dmytry
    One of the aspects of the reengineering problem of legacy Information Management Systems for complex Technological Process, related with working out of new program components, destined for storing and processing the retrospective information concerning the functioning of Technological Process, was considered. As an object for re-engineering processing the Computer-Aided Information System (CAMS) of one of the plants of Romny (Ukraine) Gas Compress Station. A new CAMS program architecture, the model of new program component, which was named as Retrospective Database, and main aspects of its software implementation are considered in this paper.

    Distributed objects performance optimization and modeling
    (Information Systems Technology and its Applications, international conference ISTA'2001, 2001) Juric, Matjaz B.; Rozman, Ivan; Hericko, Marjan; Welzer, Tatjana; Gyorkos, Jozsef
    This paper is focused on the performance analysis, comparison and optimization of distributed object middleware for Java 2: RMI (Remote Method Invocation), CORBA IDL (Interface Definition Language) and RMI-IIOP (Remote Method Invocation on Internet Inter-ORB Protocol). The paper presents the following contributions to the research on distributed object performance. First, a detailed performance analysis is provided with the comparison. These results help to understand how the models perform. Second, an overhead analysis has been done, which explains why there are differences in performance. Third, optimizations and improved performance for RMI-IIOP and CORBA IDL are presented. These show considerably better performance in all areas compared to the original versions.

    Education and technology transfer in informational fields as the part of globalization process
    (Information Systems Technology and its Applications, international conference ISTA'2001, 2001) Makarenko, Alexander S.
    It is discussed some educational and research aspects connected with informational technologies. Automation and control educational problems are considered. The issues of practical interest for Ukraine and Europe research and technological development discussed. Some new models with associative memory property are described. The description of new speciality ‘social informatics’ is proposed as the example of implementing the post-industrial society needs.

    An enterprise financial state estimation based on data mining
    (Information Systems Technology and its Applications, international conference ISTA'2001, 2001) Godlevsky, Mikhail D.; Orekhov, Sergey V.
    This paper is concerned with the data mining application to business process automation. A short tutorial on stages of financial analysis of an enterprise is given. A brief description of data mining components for financial analysis of an enterprise is presented in the paper. The main element of data mining application is fuzzy neural system. The structure of fuzzy neural system includes linguistic variable "financial state", neural network and fuzzy rules. The fuzzy neural system forms the financial state estimation based on balance sheets from dataware house of an enterprise. The data mining application has been realized as software in Microsoft Visual Basic 6.0. The software was applied to estimation of financial state of Kharkov (Ukrainian) enterprises in 1999. Finally, the set of enterprises for investment was found.
