Research papersList of all publicationsClassic methodsPrediction of the Heat Supply Daily DiagramThe paper deals with the suggestion of the method of calculation of Heat Supply Daily Diagram (HSDD) prediction for the control of district heat system. The method of superposition of models was designed with partial use of BoxJenkins model. This method is based on the probabilistic theory and mathematical statistics. The method of correction of heat demand, which is influenced by lay out of working shifts and sudden weather changes, was proposed. The aim of the prediction is to improve the quality of the control of the district heating system. Fuel and energy is saved, which contributes to economy and ecology. Dostál 1998 ISBN 8021410949 Some Knowledge of Prediction Methods This article is concerned with the importance of prediction and with various applications of prediction, and warns of the danger of forming erroneous predictions and the necessity of prediction correction. The various types and methods of prediction are described. The BoxJenkins prediction methodology, employing the autoregressive integrated moving average model, is discussed in greater detail. The article also classifies various time series and deals with the possibilities for the prediction of time series. Concrete applications of the prediction of time series are demonstrated in various fields, and the advantages and disadvantages of the BoxJenkins methodology are described. In conclusion other possibilities for prediction, outlining and other variants are mentioned for the purposes of possible further investigation. Dostál 1998 ISBN 8021412224 Forecast Model of Heat Demand The paper deals with the utilization of time series prediction for control of technological process in real time. An improvement of technological process control level can be achieved by time series analysis in order to prediction of their future behaviour. We can find an application of this prediction also by the control in the Centralized Heat Supply System (CHSS), especially for the control of hot water piping heat output. Due to the large operational costs involved, efficient operation control of the production sources and production units in a district heating system is desirable. Knowledge of heat demand is the base for input data for operation preparation of CHSS. Term “heat demand” is instantaneous required heat output or instantaneous consumed heat output by consumers. The course of heat demand can be demonstrated by means of heat demand diagrams. Most important is daily diagram of heat demand (DDHD), which demonstrates the course of requisite heat output during the day. This diagram is most important for technical and economic consideration. Therefore forecast of this diagram course is significant for shortterm and longterm planning of heat production. In this paper we propose the forecast model of DDHD based on the BoxJenkins methodology. The model is based on the assumption that the course of DDHD can be described sufficiently well as a function of the outdoor temperature and the weather independent component (social components). Time of the day affects the social components. The time dependence of the load reflects the existence of a daily heat demand pattern, which may vary for different week days and seasons. Forecast of social component is realized by means of BoxJenkins methodology. The complete forecast algorithm with inclusion of outdoor temperature is described. Finally is presented some computational results and conclusions.

Economy and Application of Chaos Theory The theory of chaos came into being in solution of technical problems, where it describes the behaviour of nonlinear systems that have some hidden order, but still behave like systems controlled by chance. A linear model can describe a real system only if it is linear. If this is not fulfilled, then such models can simulate the real system only under ideal conditions, only for a short time. If a system is a nonlinear dynamic, a deterministic system it can generate not only the permanent trends and cycles, but it can also include randomlooking behaviour. Processes of such behaviour are present in the economy. Dostál, Rukovansky ISSN: 21621357(Print), ISSN: 21621381(Online).

Not all patients go to the hospital nearest to their homes due to brand name perceptions or association with a specific physician. However, some patient migration occurs between affiliated hospitals, because of a need for special services. This represents a complex competitive environment among hospitals which can be viewed positively or negatively. The negative manner means real competition for a relatively small local community, but the positive manner means the 'partnership' of hospitals to take advantage of size, centralization, expertise, and sophisticated medical specialties which require a critical mass of activity to be effective.. In a consolidating, competitive environment requiring fewer hospital beds and expensive facilities some hospitals do not wish to compete with each other, but rather cooperate by forming hospital partnerships or oligopolies. In this constrained environment modelling or optimization effort must consider both the positive and negative ramifications of competition along with the influence of natural boundaries (such as water features and bridges that separate communities) while seeking to find strategic opportunities to serve the communities in need of Health Care Services. Dostál, Levenbach, Savage 2009 ISSN 19974116 Simulation of Production and Financial Systems The article deals with applying the simulation and identification of production and financial dynamical systems by means of second order of differential equations. The analogy and the method of build up of models are demonstrated on simple examples. Dostál 2004 ISBN 8070805501 Risk management and Soft Computing This paper deals with the use of artificial intelligence in risk management. The artificial intelligence includes the fuzzy logic, neural networks, genetic algorithms, etc. These methods can solve many problems from practice. The risk management belong among them. The use of fuzzy logic, neural networks and genetic algorithm use is presented by evaluation of risk of client. Dostál 2007 ISBN 9788024814063 Distribution Problem Solved by Artificial Intelligence Methods This article deals with the use of artificial intelligence that can solved many problems in entrepreneurial and economic field. The artificial intelligence includes genetic algorithms and neural networks. These methods can solve many problems from practice. The distribution problems belong among them. The correct solution of such problems enables us to minimize the cost, save time and nature. The methods mentioned in the article can be used for many similar cases and various places. Dostál, Kratochvíl 2009 ISSN 16871103, ISBN 9772371723 The Decision Making Under Law Uncertainty by Means of Fuzzy Logic The article deals with the use of fuzzy logic at support of manager decision making. The brief description of fuzzy logic and the process of calculation are mentioned. The use is demonstrated on the example such as the decision making whether to accept, entertain or reject the client of law office. The scheme of models, rule blocks, attributes and their membership functions are mentioned. The use of fuzzy logic is the advantage especially at decision making processes at law uncertainty. Dostál 2009 ISBN 9788073141639 The Use of Mapping Toolbox In Economy The article deals with the use of mapping toolbox in economy. There are various methods of evaluation of economic strength of the states of the world. The results of analyses and evaluations serve as a support of decision making. The results are suitable to visualise by the so called choroplets maps. Dostál, Kratochvíl, Jirkovský 2013 ISBN 9788097051945 The Simulation of ProductionFinancial Proces Via Differential Equations The article presents one of the possible methods of simulation in business, where the system of differential equations of first order is used. The productionfinancial system is searched and MATLAB program is used. Dostál 2013, ISBN 9788073142919 Stock Market and Vortex TThe article deals with the possible method of simulation  vortex theory on capital market. There is mentioned the theory and its possible use on the stock market. The MATLAB program is used. Dostál 2015, ISBN 9788073143169 Game of Firms The simulation of competitive environment of firms was based on theory of Game of life. The theory was modified on the business environment and rules of Game of firms were set up.
