- KonferenzbeitragOptimization of data sets allocation in the distributed databases(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Lazdyn, Sergiy V.; Telyatnikov, Alexander O.This paper deals with the new method of solving the problem of data set allocation optimization problem in the distributed database systems. The method is based on the combined use of object model of the distributed database and modified genetic algorithm. The criterion for optimum is defined by the minimum total average time required to process queries and disseminate updates. The experimental research of the developed method has proved that the productivity of the information system can be increased by 30\% due to optimization of the dataset allocation without the need for additional expenses on hardware modernization.
- KonferenzbeitragFragments for composing collaborative systems(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Hawryszkiewycz, I. T.; Henderson-Sellers, B.; Tran, N.Collaborative systems are characterized by groups or communities jointly working to accomplish some organizational goal. Members of the communities must coordinate their efforts to ensure that such goals are met. Development of collaborative systems can be facilitated by identifying common aspects of such coordination and by constructing product method fragments that can be composed into working systems. This paper uses a metamodel to provide a basis for such fragments, describing the metamodel and defining typical fragments.
- KonferenzbeitragUse of tailored process models to support ERP end-users(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Kristiansen, Renate; Gulla, Jon Alte; Trætteberg, HallvardModeling is essential for the success of any ERP project and early in the project a considerable amount of time and money is invested in designing and redesigning business processes. However, the models developed in this period, do not take the leap from the developers' desktops, and generally offers no support for the end-user while performing daily work. The construction of the user interface of an ERP system reflects the organizations functional areas, making the functional aspect predominant. The process aspect in a user's work is lost, and the user gets no conceptualization on how his contributions fit into the overall business processes. In this paper we suggest that tailored views of the process models developed early in the ERP project should be made available to the end-users while working with the ERP system. We show examples on models developed during an ERP implementation project at a Norwegian manufacturing company, and show how these can be tailored according to an end user's role, the current context and what instance she finds herself in.
- KonferenzbeitragTowards generic layouts for multi-channel publishing: "XF-extensible formatting"(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Tervo, Heli; Honkaranta, Anne; Leinonen, PaulaXML (Extensible Markup Language) has become the lingua franca for information integration, e-Business and metadata. It is also invading to office documents and hence becoming the format for organizational and end-user documents. XML documents themselves do not contain information about styling, i.e., how they should be rendered for print, screen, or other channels of publication. One document type may need numerous styling definitions as CSS (Cascading Style Sheets) or XSL (Extensible Stylesheet Language) stylesheets for differing multi-channel publishing purposes. Producing style definitions with differing styling languages may be quite tricky for end-users. The management of a myriad of formatting definitions may pose challenges for organizations as well. Tools for defining CSS style definitions are available but the support for differing versions of CSS on different end-user devices may be varying. Use of XSL requires programming skills or applications providing graphical user interfaces for XSL. Although there are a few commercial products available for producing XSL from easy-to-use graphical interface, there is a need for tools allowing generic styling for XML documents to be defined. The generic styling may support multiple differing formatting outputs. This paper presents a possible solution for XML document formatting. XF (Extensible Formatting language) is a generic high-level formatting language serving as a mediator for contemporary, powerful formatting languages such as CSS and XSL. A prototype implementation of XF with an easyto-use visual interface is also described. XF is based on XML and bridges the gap between end-users and existing powerful formatting languages.
- KonferenzbeitragFuzzy-logic modeling approach for system requirements management(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Tkachuk, M.; Godlevsky, M.; Zemlyanoy, A.; Gamzayev, R.
- KonferenzbeitragAn investigation of the target environment for agile methods(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Strode, Diane; Tretiakov, AlexeiThe agile methods were investigated to determine the factors making up their target environment. A theoretical model of the target environment for agile methods was developed and then tested using a multi-case study. Data from nine software development projects, both agile and non-agile, was gathered from project leaders. Then a cross-case analysis of each factor in the theoretical model explored the relationship between each of the environmental factors and the extent of agile method usage. This led to a refined model of the target environment. The empirical data showed that specific environmental factors correlate with effective use of an agile method. We also report that methods are tailored for use, and that, although agile methods are distinct from ad hoc development, the extent of agile method use must be measured before conclusions from agile method studies can be considered valid.
- KonferenzbeitragA generic ontology of rational negotiation(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Ermolayev, Vadim; Keberle, NatalyaThe paper presents the generic conceptual framework for modeling rational negotiation processes. The central piece of the presented work is the upper-level negotiation ontology. This ontology is designed to be capable to model the arbitrary types of negotiation dialogues by providing the upper-level namespace for that. The models of the specific negotiation types refine this namespace by providing the instances of its concepts, applying additional restrictions on the properties, possibly adding new subclasses and properties. The approach to model negotiations with the Generic Negotiation Ontology (GNO) is initially evaluated by applying to contracting negotiation type. The choice of the negotiation type for the evaluation is suggested by the fact that contracting negotiations are the typical encounters among the agents taking part in the simulation of a Dynamic Engineering Design Process (DEDP). This modeling activity is performed in the frame of our PSI project1.
- KonferenzbeitragA vision to construct multiple data views in peer data management systems(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Mohamed, Rozlina; Al-Mourad, M. Basel; Khalifa, Yasser M. A.
- KonferenzbeitragCoordinating higher education as an e-government initiative(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Cherednichenko, Olga; Kuklenko, Dmytro; Zlatkin, SergiyGovernment plays a key role in providing higher education. It supplies policies and regulations, information to the society, administers funds and licensing, develops standards, etc. In the context of total e-Governing Ministries of Education of many countries initiated the creation of supporting information systems. These systems in most cases are limited to providing information resources of different kinds to the society by web-portals. Administering and coordinating functions are left out for some reasons. In this paper we discover the typical structure of higher education, different stakeholders involved in the process of providing higher education services, information and data flows. We discuss the key functions that information systems must support. And finally we propose the e-Government higher education reference model to be addressed when developing such information systems.
- KonferenzbeitragSemantic interoperability in the norwegian petroleum industry(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Gulla, Jon Atle; Tomassen, Stein L.; Strasunskas, DarijusThe petroleum industry is a technically challenging business with high investments, complex projects and operational structures. There are numerous companies and public offices involved in the exploitation of a new oil field, and there is a high degree of specialization among them. Even though standardization has been considered important in this industry for many years, there is still very little integration across phases and disciplines. An industrially driven consortium launched the Integrated Information Platform project in 2004, in which semantic standards based on OWL and Semantic Web technologies were to be developed for the subsea petroleum industry. This paper presents the IIP project in more detail and discusses how industry-wide ontologies can support semantic interoperability and encourage more process integration.
