The development of information management systems stimulates the search for new forms of supporting business processes which take place in the organization. One of the solutions that can be applied here is software agents that enable support activities to the employee and the customer promoting information and knowledge about the organization. Such solutions are commercially available for several...
This article presents the problem of consensus determining postulates defining in financial decision support systems. The consensus determining methods and function is characterized in the first part. Next the general postulates for consensus estimation and their characteristics are presented. The final part of article suggest new postulates pertaining to financial decisions, and the possibility of...
Writing evidence documents for evaluation and certification processes according to the Common Criteria security standard is a very difficult, time-consuming and complex task. Nowadays there are only a few, limited solutions based on templates and software tools which can efficiently support developers in preparing evaluation deliverables. This paper describes the results of an R&D project whose...
Many Off-The-Shelf Software (OTSS) assessment techniques have been proposed, most of them using criteria related to standard quality models. However, these techniques are not as useful to evaluate and compare alternative OTSS as solutions to specific process-driven organizational changes. This article proposes PBEC-OTSS (Process-Based Evaluation and Comparison of OTSS), a technique for evaluating...
The main purpose of this paper is to assess the level of Business Intelligence (BI) maturity in organizations. The research questions I ask in this study are: (1) what possibilities offer BI systems for different organizations, (2) how to measure and evaluate the BI maturity in organizations? The study was based on: (1) a critical analysis of literature, (2) a observation of different BI initiatives...
Attribute-Relationship Diagrams (ARD) aim at capturing relations, especially dependency relation, between the specified attributes. This paper describes work-in-progress research concerning process and rules integration, which takes advantage of the ARD method and allows for generating executable models. The paper examines the possibility of generating the rule-oriented BPMN model and enriching process...
Business Process models in the case of real life systems are often very complex. Hierarchization allows for managing model complexity by “hiding” process details into sub-levels. This helps to avoid inconsistencies and fosters reuse of similar parts of models. Configuration, in turn, gives the opportunity to keep different models in one configurable model. In the paper, we propose an approach for...
Data reflecting social and business relations has often form of network of connections between entities (called social network). In such network important and influential users can be identified as well as groups of strongly connected users. Finding such groups and observing their evolution becomes an increasingly important research problem. One of the significant problems is to develop method incorporating...
Formal verification of business models has become recently an intensively researched area. Application of formal methods in this field necessities in overcoming several problems. Firstly, business analyst and designers rarely have enough skills and motivation to manually build abstract and formal specifications, hence, it arises the need to provide tools for an automated translation of business models...
The paper describes architecture of a prototype networked student information delivery system. Main system functionalities include interactive access to lecture room timetables and group messaging. The system exploits modern mobile technologies to allow flexible usage scenarios. The use of open APIs of telecommunications service delivery platforms in combination with e-mail messaging provides diverse...
In this paper, the system presents an integrated wireless sensor network (WSN) to monitor the information from agriculture systems namely temperature, humidity, pondus hydrogenii (pH) value…etc. The purpose is to provide a faster and more convenient platform for the client to obtain information from an array of sensor nodes that has been set-up in an agricultural system. A WSN will collect the values...
In recent years, smart-devices became very popular among people of all ages around the world. Very important is especially their usage in health applications. Special Body Area Network (BAN) for the stress monitoring is currently being developed within the authors' department. Android-based smartphone is employed as the main control unit of the sensor network built on the star architecture. Since...
The extensive use of the Wireless Sensor Networks (WSNs) in main critical scenarios stresses the need to verify their dependability properties at design time to prevent wrong design choices and at runtime in order to make a WSN more robust against failures that may occur during its operation. In literature, several approaches have been proposed in order to evaluate the dependability of a WSN during...
The following paper presents Mobile Payment System. The system is a prototype of an innovative method of paying for services using the mobile phone. The method is quite straight-forward, basically the user wanting to access some online service supplies his/her cellular phone number to the web form and receives a token via USSD message (Unstructured Supplementary Service Data). Then, introducing the...
Traditional wireless sensor nodes are designed with low-power modules that offer limited computational performance and communication bandwidth and therefore, are generally applicable to low-sample rate intermittent monitoring applications. Nevertheless, high-sample rate monitoring applications can be realized by designing sensor nodes that can perform high-throughput in-sensor processing, while maintaining...
This paper discusses factors influencing accuracy of estimating localization of radio networks terminals in indoor environment. It introduces parameters that can be useful to describe the quality of localization of radio landmarks. The paper presents a software for computer aided reference radio stations placement inside the buildings and shows the results of exemplary simulations carried out with...
