As the most valuable resource, information has become a key factor in deciding the levels of national productivity and economic growth. But there are lots of risks in the implementation. Risk assessment is an effective approach to evaluate security state of information system. In this paper a model of information system risk assessment based on its characters of incompleteness and ambiguity is presented...
Since 1996, land detailed investigation project and the second-time land resources survey and monitoring project have been developed one after another. The methods of land resource management have been a shift from the traditional manual method to the modern information means, as the corresponding information technology has been utilized in processing, statistics and updating the database, of which...
The paper firstly proposed an evaluation index system for high-tech projects investment risks from six aspects, and then built the investment risks evaluation model of high-tech project based on analytic hierarchy process (AHP). Through the analysis, we obtained the weights of each risk index, which provided basis for decision-making.
In view of the existing problems of investment risks evaluation on high-tech industry projects such as a lack of systematic, with too much subjectivity and from the point to improve evaluation efficiency and effectiveness, the paper combined analytic hierarchy process (AHP) with BP neural network to establish a new and suitable risk evaluation model of high-tech projects. Firstly, we applied AHP to...
In the market economy, the cost of purchasing is one of the factors affecting the profit, so apply the theory of ldquodominant strategyrdquo to the process of purchasing, the decision-makers can control the daily transaction of purchasing more smoothly, and thus to realize the purpose of controlling and reducing cost. Practice shows this model is fairly reasonable and scientific especially applying...
Logistics demand is an important factor of deciding the development policy of logistics industry and plan and construction of the logistics park. According to the actual situation in Heilongjiang province and the raw data analysis of railway freight volume in recent year, this paper built the grey forecast mode and provides the theory reference for the government to plan the development of logistics.
Network marketing is a new marketing approach which may open up a broader market for agricultural products trade, strengthen the links between farmers and the outside world, promote the sales of agricultural products, improve the relationships between farmers and customers, and help farmers analyze market needs to decide the production direction, so it is very important to evaluate the performance...
Logistics center location influenced by various indictors is crucial to logistics planning. According to 21 evaluation index, this paper established the reliable artificial neural network mode and made decision research on logistics center location. The result of the example showed that compared with multi-class fuzzy comprehensive evaluation, artificial neural network model possesses the characteristics...
Based on unascertained theory, the paper introduced the modeling process of unascertained measure evaluation. Unascertained measure model can achieve ordered division on evaluation space and improve the discernibility degree, which produces reliable evaluation results. Applying the unascertained measure model to analyze and evaluate the community informatization level may provide new ways and means...
The traditional training model overlooked the importance of teaching practice, the traditional practice of teaching methods so that students are unable to learn through real application, ERP platforms simulation courses changes in the traditional pattern of train personnel, emphasizing training, experience and practice, so that the students learn the knowledge mutual penetration, which train students...
