Academic literature on the topic 'Computer network - Administration'

This dissertation investigates the performance of a problem solving group whose members are constrained to communicate only through a computer network, a situation that has become commonplace with advances in computer technology. The model of group decision making adopted specifies that the group outcome is a function of six independent variables. They are group size, the incentives offered to group members, the decision rule used to combine member inputs, the distribution of information among members, the complexity of the task, and mode of communication (face-to-face or computer network). The dependent variables are group decision quality and members' perceptions of the group process. A laboratory experiment was conducted to study the effect of the computer network on the dependent variables. The group task required the generation and evaluation of alternative production plans for a candy company that has five divisions, each of which was managed by a group member. The five managers worked together as members of the corporate committee to decide on the allocation of a limited amount of Milk and Cocoa to the divisions. After this allocation was accepted, each manager decided on his/her divisional production plan subject to a local constraint. Three treatments were investigated: face-to-face (manual) groups, computer networked groups, and computer networked groups where the group members selected a Chairman to make the allocation decision. Information about the common resources and the overall profit function was public while the division information was private, but could be shared over the network. The decision rule was unanimity and each member of the group received a cash payoff based on successful completion of the task and the amount of company profit. Manual groups achieved the highest profit followed by computer groups, and computer groups with chairman, in that order. Manual groups also achieved the highest distribution efficiency and divisional efficiency suggesting that the average member attained a better understanding of the problem in the manual condition. It appears that the computer network degraded group decision performance and electing a chairman exacerbated the trend. The satisfaction of members was lower in the computer conditions that the manual condition. Contrary to some past research that used roughly similar tasks, participation by group members was not felt to be more even in the computer conditions than the manual condition. Also, manual groups perceived their group process and solutions to be more effective than the computer groups. These results would seem to indicate that if high decision quality is the primary purpose of a group meeting then face-to-face interaction among the group members may be necessary even though creating such conditions may be expensive.

There exist intelligent agents to aid online sellers to dynamically calculate a competitive price for their products in online markets. However, these intelligent agents usually make a number of assumptions for dynamic pricing. Some intelligent agents assume that sellers consist of prior knowledge about the online market parameters. In other words, the agents assume that the sellers are well aware of other competitors' pricing strategies, consumers purchase preferences, consumers' reservation price, profit made by other competing sellers etc. In addition, other agents assume that price is the only attribute that determines consumers' purchase decision. On the contrary, in real life sellers have limited or no prior knowledge about the market parameters. In addition, nowadays along with price other attributes such as after sale service, product quality etc. contribute in determining consumers' purchase decision. In this thesis, we propose an approach where sellers have limited knowledge on market parameters. We also assume that buyers' purchase decisions are based on multiple attributes. We are using a feed-forward neural network approach for calculating a competitive price dynamically to increase the sellers' revenue. Product price, product quality, delivery time, after sales service and seller's reputation are taken into consideration while determining the competitive price of the product by our model. In our experimental evaluation we showed that once the sellers, by considering the five attributes, set an initial price of the product, our model adjusts the price of the product automatically with the help of neural network in order to raise the revenue. In setting the initial price of a product, we assume that sellers use their prior knowledge about the prices of the product offered by other competing sellers. Any other prior knowledge like buyer demand or competitor's price setting behaviors is not used in our evaluation. The experimental results portray the effect of considering the five attributes in earning revenue by the sellers. Before concluding with directions for future works, we discuss the value of our approach in contrast with related work.

Entretanto, as técnicas e ferramentas utilizadas por esses profissionais não conseguiram acompanhar a evolução de uso do poder computacional. Na tentativa de auxiliar os administradores, várias ferramentas foram desenvolvidas com o intuito de possibilitar uma maneira mais simples, rápida e eficiente de configurar e administrar um parque tecnológico. Porém, muitas delas ainda apresentam impossibilidade, principalmente pela necessidade da presença física do administrador no ambiente que se administre. Deste modo, considera-se que as ferramentas de administração não atendem às necessidades julgadas essenciais aos cenários atuais. Neste contexto, esse trabalho apresenta um estudo das consideradas principais e mais populares ferramentas de administração computacional, analisando-as e comparando-as. Propõe também um novo modelo de ferramenta de administração, que busca solucionar as limitações encontradas nas ferramentas estudadas, como apontar novas possibilidades a esta área<br>Abstract: Due to the huge impact caused by systems and computer networks nowadays, computer administrator's activities have become fundamental to their organizations. On the other hand, the techniques and tools used by these professionals didn't improve as much as the computing power of the machines we have available now.In order to assist computer administrators, several tools were developed to allow a simpler, faster and more efficient way to configure and manage several machines. However, many of these solutions arc still unable to manage and configure their systems and networks without the physical presence of the System Administrator.Therefore, these tools are not of satisfying the requirements considered essentials to the current scenarios. In this context, this work shows a comparative analysis of the main and most popular computer management tools available. It also presents a new approach to remote administration, with the purpose of solving the limitations found in the analysed tools, and indicates the new tendencies and possibilities in this field<br>Mestrado<br>Sistemas de Computação<br>Mestre em Ciência da Computação

<p>Ericsson develops and builds mobile telecommunication networks. These networks consists of a large number of equipment. Each telecommunication company has a staff of administrators appointed to manage respective networks. </p><p>In this thesis, we investigate the requirements for an access control model to manage the large number of permissions and equipment in telecommunication networks. Moreover, we show that the existing models do not satisfy the identified requirements. Therefore, we propose a novel RBAC model which is adapted for these conditions. </p><p>We also investigate some of the most common used commercial tools for administrating RBAC, and evaluate their effectiveness in coping with our new proposed model. However, we find the existing tools limited, and thereby design and partly implement a RBAC managing system which is better suited to the requirements posed by our new model.</p>

The purpose of the project was to develop a teacher handbook forusing computer technology and Microsoft Office XP software in the performance of their administrative tasks. The handbook was designed to provide teachers with step-by-step instructions that would enable them to automate many administrative tasks that were previously performed manually, without the benefit of computer technology.

Every day system administrators perform many tasks that share one common requirement: information about the system.This information has to be up-to-date and reliable.To collect this information on demand and manually is time consuming and labour intensive.In the Network and Systems Administration (NSA) lab environment at the University of Skövde, there are many computers which need to be administrated.Today this is done by using a shared spreadsheet, a costly method with drawbacks.This project will search for answers to the question ``How can an automated client inventory improve the work of administrators at the NSA lab?''.To answer this question, a prototype will be created and its performance compared with the manual collection of information.In order to create a realistic and useful prototype, a list of requirements for inventories has to be assembled.The prototype has additionally to take the peculiarities of the NSA lab environment into account.The information has to be gathered without any permanent installation of a client, as there are no internal hard drives available.This detail makes it impossible for already existing applications to be deployed.The NSA administrators will then compare the performance of the prototype with the manual collection of data. They will conduct a trial during which they will be observed and afterwards answer some questions about the process. The results of the analysis of this data yielded a number of hypotheses.Common concepts like the time saving by automation get supported by this projects findings, but also less obvious observations are made. With the help of an automated network inventory administrators can become proactive and fix potential issues before they become problems.The extraction of information from a network inventory requires less knowledge about system administration, as the information is presented in an user interface.The user does not need to gather data as this is done by the network inventory.Only the extraction of the right information from the user interface is required.Information useful to the continued development of the prototype was collected as well. Improvements to the user interface as well as more automation should be added to the prototype in order to further improve the efficiency compared to the manual collection of information.

Thesis (MTech (Information Technology))--Peninsula Technikon, Cape Town, 2005<br>The overall objective of this study is to identify the importance of culture in the implementation of Information systems and how output influences the success of a system. • The first objective is to assess the organizational culture in each hospital in terms of one of the dimensions of culture on Hofstede's checklist, namely power distance. • The second objective is to determine whether the speed with which a HIS was implemented was a success at the two academic hospitals in the Western Cape using the reduction of the level of backlog (paper based patient registration records) as a measure of implementation progress.
