Business processes are omnipresent in nowadays economy: companies operate repetitively to achieve their goals, e.g., deliver goods, complete orders. The business process model is the key to understanding, managing, controlling, and verifying the operations of a company. Modeling of business processes may be a legal requirement in some market segments, e.g., financial in the European Union, and a prerequisite for certification, e.g., of the ISO-9001 standard. However, business processes naturally evolve, and continuous model adaptation is essential for rapid spot and reaction to changes in the process. The main contribution of this work is the Continuous Inductive Miner (CIM) algorithm that discovers and continuously adapts the process tree, an established representation of the process model, using the batches of event logs of the business process. CIM joins the exclusive guarantees of its two batch predecessors, the Inductive Miner (IM) and the Inductive Miner – directlyfollows-based (IMd): perfectly fit and sound models, and single-pass event log processing, respectively. CIM offers much shorter computation times in the update scenario than IM and IMd. CIM employs statistical information to work around the need to remember event logs as IM does while ensuring the perfect fit, contrary to IMd.

Purpose: The aim of the publication is to diagnose the level and to assess the possibility of using managerial dashboards created in an Excel spreadsheet to supervise management processes in enterprises. Design/methodology/approach: The research developed the method of a directed interview with the staff at various management levels. The supervision of technological processes, economic analysis, and the provision of broadly understood services for citizens have been the subject of the research. Findings: Managers show little interest in improving their employees' analytical skills. Training in this area is not planned and the impact of analytical capabilities of the tools available for the functioning of the company are not appreciated. Research limitations/implications: The results of the research are not representative, but they encourage the authors to carry out a broader and more in-depth analysis of the existing situation in enterprises. Practical implications: The research shows the need to rationalize human resources management. This process requires an increased supervision over employee development planning with the use of the appropriate training. This may have a significant impact on efficient management and, consequently, on the company's financial results. Originality/value: The article is to be an element stimulating the management to more thoughtful activities in the field of selection, training, and use of personnel at various levels of management in the company.

Nowadays, identification and neural methods are used more and more often in modeling IT forecasting systems in addition to analytical methods. Six characteristic models used to forecast the Day- Ahead Market system functioning as a transaction management system at the Polish Power Exchange (POLPX) and the Nord Pool Spot market have been selected for comparative analysis. The research was preceded by a detailed discussion of modern criteria used to assess the quality of model fitting to the system, namely: effectiveness, efficiency, and robustness. In the literature, there are two main groups of system modeling methods, namely time series modeling methods and identification modeling methods, including neural modeling methods. Modeling usually results in such models as parametric models and artificial neural networks learned neural models of the Day-Ahead Market, as well as time series models, among others. In the comparative analysis, special attention was paid to the accuracy of the obtained models concerning the system. It has been pointed out that the studied solutions used to measure the accuracy of modeling criteria such as accuracy of fit or efficiency, and did not use the modeling efficiency, which is very important in IT forecasting systems for such large markets as the Day-Ahead Market of POLPX. The search for the best market models, including identification models of the Day- Ahead Market operation that can be used in electricity price forecasting is a very important issue both from the point of view of algorithmic solutions and economical solutions.

Benchmarking is a modern method of management that creates opportunity to improve, measure and compare own results with the leader’s results and then to describe its various forms. The author emphasizes the importance of information being a valuable resource of the company and at the same time being the basis for applying the benchmarking method. It is worthwhile noting that not all information that reachesthe organization is useful. Therefore, the need to analyze and evaluate information becomes more and more important. In this work, the methods of obtaining information directly and indirectly have been distinguished. In the last part of the work, the concept of "business intelligence" was explained and various variants of it were listed and explained. The problem of economic espionage and methods that can be used by people who want to obtain data for benchmarking was also outlined. However, it is worth noting that both concepts of business intelligence and economic espionage share a very thin border.

Today’s increasing hurriedness in our way of life along with technology advances demand from businesses to react always in a faster mode, while maintaining or, better yet, improving the quality of their products and services. Towards that objective, businesses can gain benefits by employing redefined team-building processes through which teams will be generated in a more cohesive and efficient manner. Aiming at forming productive and effective teams, we present PROTEAS, a framework where professional profiles and personality traits are both taken into account in the teambuilding process. The professional portrait of users is drawn from their LinkedIn accounts, while hints for their personality are obtained by a well-defined questionnaire based on the Big Five Factor Model. The significance of personality is substantiated by recent research work where it has been proven that personality traits can play a vital role in group dynamics. Motivated by the latter, PROTEAS defines a series of variables where characteristics of team members (e.g. skills, education) are combined with personality traits towards identifying candidate teams. All candidates are evaluated via a weight-based algorithm which calculates pair-wise similarities among teams’ members and ranks the teams accordingly at the end. To assess the effectiveness of PROTEAS an academic setting has been chosen and through the experimentation a number of interesting observations occurred which are analogous to those of similar researches, confirming the significance of personality and professional compatibility between team members.

Business Intelligence promises improved decision making. To meet the changing business requirements, BI has to reduce latency between data acquisition and decision. As a result of growing needs, concepts like Real Time, Active, Operational, Business Performance Management or embedded BI are introduced in the literature. Nevertheless, the technical implementation prevents the realization of these concepts. Thus, overloaded infrastructures and heterogeneous system landscapes avoid further evolution. To prevent this lack of system integration and performance, we address the changing BI paradigms through a service-oriented approach. Hence, the novel BI concepts and Service-oriented Business Intelligence (SoBI) theories are illustrated and combined in a uniform artifact. The construct is developed by using reference modeling. As a result, a SoBI reference architecture accrues, which becomes validated successfully and provides a basis for future implementations. This paper offers a flexible approach that reduces the latency in order of dynamic market environments.

Data integration is a crucial issue in the environments of heterogeneous data sources. At present, the afore-mentioned heterogeneity is becoming widespread. Based on various data sources, if we want to gain useful information and knowledge, we must solve data integration problems in order to apply appropriate analytical methods to comprehensive and uniform data. Such activity is known as knowledge discovery from the data process. Therefore, approaches to the data integration problem are very interesting and bring us closer to the “age of information”. This paper presents an architecture which implements knowledge discovery from the data process. The solution combines ETL technology and a wrapper layer known from mediated systems. It also provides semantic integration through connection mechanism between data elements. The solution allows for integration of any data sources and implementation of analytical methods in one environment. The proposed environment is verified by applying it to data sources in the foundry industry.
