The paper presents the method of a group decision making in a competitive environment. We deal with a group decision when the group of people with different preferences are to make one single decision. The group decision selection process is modeled with the use of multi-criteria optimization task. It is solved with the use of reference point method. This method is an interactive method in which every...
Many methods can be used for the evaluation of website quality. While they can be used for different purposes and require different assessment approaches it is not easy to select proper method adequate to the needs. Presented research is focused on building a repository of knowledge about the methods for the assessing the quality of website. The repository in the form of ontologies covers various...
Steadily increasing complexity of software systems makes them difficult to configure and use without special IT knowledge. One of the solutions is to improve software systems making them “smarter”, i.e. to supplement software systems with features of self-management, at least partially. This paper describes several software components known as smart technologies, which facilitate software use and...
The article presents the approach to the conceptualization of the financial knowledge used for an Intelligent Dashboard for Managers. The content of the knowledge is focused on essential financial concepts and relationships related to the management of small and medium enterprises (SME). That includes the illustration of the conceptualization of the ontology. The designed ontology was split into six...
Performance Measurement Systems (PMS) have long captured the attention of organizational behavior and information systems (IS) research. The PMS in the study was implemented by public police forces, using advanced Business Intelligence (BI) technologies. The study examines the impact of enhancing that PMS, through analysis of the metric results over an 8-year time period that covered a transition...
The article comprises the characteristics of traditional project management (TPM) and agile project management (APM) and indicates that when using a specific concept we should take into account the conditions of the sector in which the organization implementing or participating in IT projects is functioning. For it is not in all organizations that APM is more effective than TPM. Agility at the project...
This paper presents issues related to a process of the automatic summarization of the text documents connected with economic knowledge performed by the cognitive agents in an integrated management information system. In contemporary companies, the unstructured knowledge is essential, mainly due to the possibility of obtaining better flexibility and competitiveness of the organization. Therefore more...
The article presents the application of a fuzzy logic in building the trading agents of the a-Trader system. The system supports investment decisions on the FOREX market. The first part of the article contains a discussion related to the use of fuzzy logic as an agents' knowledge representation. Next, the algorithms of the selected fuzzy logic buy-sell decision agents are presented. In the last part...
Taking an existing large-scale simulation model of the German toll system we identify possibilities for parallelization in order to enhance simulation performance. We transform parts of the model from its current serial implementation to a parallel implementation. Afterwards we evaluate the achieved performance enhancement and compare the results to a synthetic benchmark model.
A growing number of users, seeking to influence their friends, are adopting social network sites, like Facebook to increase their social presence. In the relatively few scholarly studies that consider how writing comments on social network sites influences their friends, the focus has been on marketing or promotion. Little is known about the impact of user writing versus reading on social media. In...
The concept of Internet of Things appeared several years ago and in that time has evolved into one of pillars of the new technologies sector. The next step is to add the artificial intelligence to Internet of Things systems. Artificial intelligence is increasingly used in everyday life. It is a concept of a wide range and applies in practice in many fields of science. The aim of presented paper was...
The aim of our study was to provide a contribution to the research field of critical success factors (CSFs) with a focus on SCM system implementations. Therefore, we conducted a systematic literature review in order to identify CSFs for those projects. On the basis of that review, we conducted interviews within German large-scale enterprises and with consultants experienced with SCM system implementations...
A term of transaction which has its origin in database processing, representing a set of operations that must be performed all or none of them. The notion of transaction is also used in some business process modeling approaches such as the DEMO (Design & Engineering Methodology for Organizations) and the REA (resource-event-agent) value modeling approach. The DEMO's transaction forms a basic building...
