The majority of formal description for software testing in the industry is conducted at the system or acceptance level, however most formal research has been focused on the unit level. This paper shows formal test selection and analyzes criteria for system or integration test based on visualization analysis for low level test cases. Visual analysis for low level test case selection is to be based...
This paper presents object-oriented design of library meant for modeling and simulating Timed Colored Petri Net models. The approach is prepared to integrate TCPN models with crucial parts of larger applications implemented in object-oriented languages. The formal models can be tightly joined with applications allowing the latter to interpret states of the formal model in their domain of responsibility...
Functioning in an era of knowledge is forcing organizations to manage this valuable resource in exact way. Very frequently activities of organizations are dependent on the application of knowledge, sometimes even means “to be or not to be” for enterprise. Nowadays, to fulfill business goals of institutions it becomes fundamental for them to use intelligent systems supporting comprehensive management...
Diagrams are an effective and popular tool for visual knowledge structuring. Managers also often use them to acquire and transfer business knowledge. There are many currently available diagrams or visual modeling languages for managerial needs, unfortunately the choice between them is frequently error-prone and inconsistent. This situation raises the next questions. What diagrams/ visual modeling...
Competence management systems are an important addition to knowledge management systems. Competencies can be processed, during the identification, assessment and acquisition processes, because there is a certain set of tools used to test competencies and estimate their levels. In this paper, we focused on the analysis of the concept of Dynamic Competence Management System. The system takes into account...
Corporate amnesia is a phenomenon that has persistently threatened the livelihood of business organizations and their success in commercial activity. Several substantial studies on this observable fact have been undertaken with focus primarily aimed at the large corporations and the small to medium sized organizations. This vulnerability is however evermore present and significant within the smaller...
Publicly available Web search engines suffer from several limitations, which significantly reduce usability in particular cases. The most important limitations are out-of-date information, very simple query language and limited number of results. In many cases, users of the Internet are interested in finding new information which appear in the particular Web portal. In this paper, a system for monitoring...
The purpose of the present paper is to discuss the results of research conducted in 2012 in order to determine the role of Internet as the source for acquiring the medical information in a group of students. Obtained results confirm the assumed working hypothesis about big role of Internet as the source of medical information that the searching for medical information in Internet is the principal...
This document presents a problem of knowledge conflict appearing in Business Intelligence systems. The structure of such class system in context of knowledge creating is presented in the first part of article. Next, the formal definition of knowledge structure of Business Intelligence, which is necessary to comparing these knowledge, was elaborated. The characteristic, sources and examples of knowledge...
One of the challenges of knowledge management is handling inconsistency. Traditionally, it was often perceived as indication of invalid data or behavior and as such should be avoided or eliminated. However, there are also numerous situations where inconsistency is a natural phenomena or carry useful information. In order to decide how to manage inconsistent knowledge, it is thus important to recognize...
Nowadays, a considerable number of enterprises develop new products using an Enterprise Resource Planning (ERP) system. One of the modules of a typical ERP system concerns project management. Functionalities of this module consist of defining resources, company calendars, sequence of project tasks, task duration etc. in order to obtain a project schedule. These parameters can be defined by the employees...
This work presents the analysis of evaluation concerning the articles that are send to publication in academic journals, basing on additional parameters not resulting from essential value of the research work. Currently, majority of article verification algorithms is oriented on the selection of such works that are potentially more strongly influencing the international position of journal. For that...
Multimemetic algorithms (MMAs) are a subclass of memetic algorithms in which memes are explicitly attached to genotypes and evolve alongside them.We analyze the propagation of memes in MMAs with spatial structure. For this purpose we propose an idealized selecto-Lamarckian model that only features selection and local improvement, and study under which conditions good, high-potential memes can proliferate...
The paper addresses tools that support knowledge-based management. These tools are referred as Business Intelligence. Competitive Intelligence is also discussed. They transport data into comprehensive information about company processes and real-world impact on their progress. Basic principles of these applications are also described. The paper presents the results of the questionnaire survey conducted...
Most companies have a large number of projects that they would like to do for various reasons. However, usually there is never enough time and money available to complete all of them. Selecting a portfolio from available project proposals is crucial for the success of each company. This paper proposes a practical framework for modelling projects portfolio selection problem with fuzzy parameters resulting...
In the last decade the need for portable Surface Plasmon Resonance (SPR) biosensors capable of on-site simultaneous multiple assays increased steadily. Several devices are available affected, however, by limitations in terms of costs, size, complexity and portability.
The paper presents the development of a new system that is used to solve the problem of the recognition of the dermatoglyphic pattern and the understanding of the classification process of the symptoms of Down's syndrome. The method used in the system for diagnosing Down's syndrome in infants is based on the combination of text knowledge found in the scientific literature describing Down's syndrome...
This paper describes a neural system which helps to make the current investment decisions. Some well known financial indicators usually considered by investors are inputs of the system. The basic problem is to select appropriately the indicators which would give the best predictor. Two methods are used and compared: the combination method and the correlation method. To analyze the problem daily quotations...
In this article some novel scheduling heuristics for Multi-Skill Resource-Constrained Project Scheduling Problem have been proposed and compared to state-of-the-art priority rules, based on task duration, resource salaries and precedence relations. New heuristics stand an aggregation of known methods, but are enhanced by skills domain. The goal of the paper is to investigate, whether evaluated methods...
