In current work problems and requirements for demand forecasting in commercial or manufacturing enterprises are analyzed and suitable forecasting algorithms are proposed. In enterprises with multidimensional and heterogeneous demand it is advisable to use different algorithms for different demand constituents and to readjust parameters used for forecasting. Existing forecasting packages are not practical as they are not integrated with commodities or materials supply orders management activities and business processes of enterprise. The orders management system is developed with forecasting component using adopted time series forecasting techniques such as moving average, exponential smoothing, double exponential smoothing. These techniques ensure reliable forecasting results for different time series models: random, trend and are integrated with other business management activities. It is possible to calculate deviations of forecasted demand from factual values, to select algorithms giving minimal perсentage error, and to adjust algorithms parameters to changing demand. The system can help managers to choose forecasting algorithms and to adapt their parameters in the course of time. The system is designed using UML CASE tool and implemented in Microsoft .Net environment using MS SQL Server 2005 for data storage.

In modern, rapidly changing society, the systems of education had become variable, situation of activity for schools and pedagogues. In Lithuania, as in many other countries, economical, political, cultural life interdependence becomes stronger. Rapidly established informational society. Obviously, because of that always changes the content of training, increasing innovations and it’s spreading need. The object of investigation – is an innovation activity of technology teachers. The aim of investigation – is to analyze peculiarity of innovation activity of technology teachers. The objects of investigation: 1. To detect the conception of innovation activity for pedagogues, while analyzing scientific educational and psychological literature. 2. To detect the conception of innovation for technology teachers. 3. To investigate the point of view for innovation activity of technology teachers. 4. To investigate the peculiarity for innovation activity of technology teachers. The investigated: 100 pedagogues working in Lithuania, teaching technology subject: 80%-woman, 19%-man. The methods of investigation: Theoretical: studying and analyzing science literature sources. Empirical: questionnaire test was applied trying to achieve the conception of innovation activity for technology teachers. Statistical: was used to achieve the statistic results of investigation information. Information was processed with computer statistic program SPSS (Statistical Package for Social Sciences) for...

E-Commerce can be used to support and improve various areas of business activity, as well as provide new business opportunities not possible before eCommerce. The main reason for it’s rapid expansion was the development of new networks, protocols and ECommerce software. E-Commerce involves buying, selling, transferring or exchanging products, services and/or information via computer networks and is a major distribution channel for goods, services and managerial and professional jobs. At the moment E-Business technologies became one of leading fields for developing and improving new standarts, protocols, solutions in the IT world.

Web pages written with simple web development technologies were either written in code (such as C with CGI, or Java with Servlets) which contained lots of HTML-writing code snippets, or written with numerous code segments embedded in HTML (such as PHP or ASP). This led to problems as increasingly sophisticated Web page designs got harder and harder to 'activate' with data, and become increasingly brittle when dealing with change requests. Complex Web pages development forces to use new technologies that helps in development phases. It is possible to separate business logic from presentation using template engines. It’s not easy to choose a proper template engine system. We classified existing template systems. By this way analysis were accomplished. Using web template system, which supports compilation and caching features combining with MVC element data abstraction, we proposed web applications development model. In this work our proposed model has been applied for the development of students practice jobs - web portal. This portal was realized using PHP technologies which includes Smarty template engine, data abstraction class PEAR::DB and PHP 5.0 programming language. We research our proposed web development model performance characteristics. Performance experiments were done with Smarty template engine and PEAR::DB data abstraction class.

Manufacturing execution system "MeatMaster" for meat processing company - labeling module Most of meat processing companies in Lithuania and other Baltic countries are sophisticated and their productivity have increased. Strong competition in market motivates the companies to seek for methods how to raise efficiency in accounting. ERP systems implemented in most of companies doesn’t secure the effective management of production and accounting. Therefore the companies are investing in a development of Manufacturing execution systems and their installation. In this project the process of production labeling in meat processing company “Utenos mėsa” is analysed. Equally, the main problems are described and are offered the solutions. In this project the requirements for the software were specified, described the designed part of Manufacturing execution system "MeatMaster" labeling module, user documentation and system installation process at a company and the results of installation.

Computer technologies progressively penetrate into the education, have influence to learning and teaching of various subjects, and to all the training process. When teaching physics, computer technologies extend facility. There can be made many experiments, which practically are very expensive or sometimes even dangerous, and take a long period of time. There can also be created computer simulators, explored phenomena, which cannot be investigated realistically. Simulators and simulation are very important in physics. Experimentation and simulation programs can be useful for the development of the computer simulators. Using these programs the parameters of the simulating phenomena can be changed, their operating can be observed, the phenomena can be simulated and their consistent pattern can be investigated. The teaching computer simulation is important as it makes the educational process more attractive and dynamic. In the master’s work “Computer Simulation Technologies of the Physical Phenomena”, there is the analysis of the usage of computer simulator’s method at schools and universities of Lithuania. With reference to the general programs of Lithuanian education and its standards, there is made the analysis of knowledge of simulation during the lessons of different subjects. With the reference to the 2004/2005 years university programs of Lithuania, there is made the analysis of the simulation courses in different faculties of Lithuanian universities. When building the... [to full text]

The work provides the results of the survey on the present situation of salary calculation information systems in the market trying to distinguish advantages and disadvantages of the usable systems, their compatibility with organizations’ administrative information systems as well as possibilities to adjust them to the requirements of users. The survey confirmed that most of examined information systems are either old, or cause many problems then combining them with organizations’ administrative information systems. Moreover, only some of the examined salary calculation information systems provide users with a possibility to change calculation formulas, reports or other properties of information system. This work presents the description of adaptive salary calculation model. This model gives the version of a possible solution of a problem which reduce the influence of determinate salary calculation information systems’ drawbacks. In this work preferred basic diagrams and descriptions of adaptive model of salary calculation. Late was created project of adaptive model of salary calculation according to diagrams and descriptions. Development of adaptive model of salary calculation gives possibility to change calculation formulas, reports and other properties of information system. Analysis gives that adaptive model of salary calculation information system solves the problem and is more comfortable for the user then other salary calculation information systems.
