The model of occupational rehabilitation center‘s information system and its realization Recent politics and legislation of social integration to the society of disabled people in Lithuania is linked towards an understanding that disabled people are responsible for their lives and should be able to take care of themselves. That is the reason why only a need of manual rehabilitation is fairly enough to help people with various disabilities to come back to their active lives and to the labor market. To achieve these goals is only possible with the occupational rehabilitation which is also a great help of empowerment to develop common and special competences. In Lithuania new occupational rehabilitation centers are being established in order to solve problems of this kind. These rehabilitation centers are in great need of new information systems, which would computerize some of the center workers functions letting accomplish them faster and in better quality. With a help of information system it would be much easier to overlook and update the information, list the news, order center‘s services. The purpose of this thesis is to identify the needs of occupational rehabilitation center‘s workers and the disabled clients; using the evaluated data to construct a model of information system and to create such system‘s prototype. The conclusion of the thesis is that the needs of the system users were identified and creation of CMS was chosen. The CMS themselves, their types and main... [to full text]

The information system created performs the following functions: standardizes the process of failure registration and management; allows monitoring and receiving information in different sections adapted for certain groups; provides opportunity to evaluate the existing situation of provision with equipment and plan future investments within time scale; allows service of a whole group of users in one time. The information system has been created by using open source software – which enables to avoid additional investments.

In security engineering and computer security, authorization, is a part of the operating system that protects computer resources by only allowing those resources to be used by resource consumers that have been granted authority to use them. Resources include individual files or items data, computer programs, computer devices and functionality provided by computer applications. Examples of consumers are computer users, computer programs and other devices on the computer. Authorization process makes use of the authentication process to identify consumers. When a consumer tries to use a resource, the authorization process checks that the consumer has been granted permission to use that resource. Permissions are generally defined by the computer's system administrator in some types of "security policy application", such as an access control list or a capability, on the basis of the "principle of least privilege": consumers should only be granted permissions they need to do their jobs. Older and single user operating systems often had weak or non-existent authentication and authorization systems. "Anonymous consumers" or "guests", are consumers that have not been required to authenticate. They often have very few permissions. On a distributed system, it is often desirable to grant access without requiring a unique identity. Familiar examples of authorization tokens include keys and tickets: they grant access without proving identity.

In this thesis are analysed correctness for verification ability of UML activity diagrams by using hypergaphs. There suggested the transformation from UML activity diagram to hypergraph and verification algorithm of hypergraph, which can be used for expanding the capabilities of CASE tools for workflow and e-business modelling.

Considerating software, that will be used to create system. Reviewing similar existing products. In practical part , the created system is descriptive, it‘s operations, user settings, testing results, problems that came during the development process and conclusions.

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.

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.
