Based on the theory of cascaded reservoirs long-term optimal scheduling, a stochastic dynamic programming with POA method was presented. A real instance was given to testify the arithmetic, and the results show this method has a good performance.
For resolving the problem that the existing protocol of secure two-party vector dot product computation has the low efficiency and may disclose the privacy data, a method which is effective to find frequent item sets on vertically distributed data is put forward. The method uses semi-honest third party to participate in the calculation, put the converted data of the parties to a third party to calculate...
Designing an energy efficient algorithm is one of the most important challenges in wireless sensor networks (WSNs). In this paper, we present a node sleeping algorithm based on the minimum hop routing protocol to minimize energy consumption. The proposed scheme divides all the nodes except the sink node into terminal nodes and intermediate nodes according to their different functions. Terminal nodes...
It is a new subject to calculate combining capacity of combination station for heavy haul trains. The paper compared the differences between combination stations and common marshalling stations, and pointed out the particularities of station arranging type, operation features, and operation process of trains in combination station. Based on statistical analysis of data to gain the probably distribution...
In view of the uncertain relationship between faults and symptoms in the water-steam system of power plant, this paper proposed a fault diagnosis method based on credibility theory. A fuzzy diagnosis model which is practical and effective was constructed by describing the issues of knowledge representation, choice of control mechanism and construction of uncertain algorithm. Simultaneously, in order...
Kenya's public sector is at a crossroads today in facing the challenges of institutional change and the impact of new technologies. The public sector can, and will play a much stronger role in implementing all the government plans. The emerging ICT technology can create solid improvement in offering better services to all nations. This can enable the citizens of the countries to access e-services...
When entering the 21st century, the foreign assets and the number of oversea agencies of Chinese commercial banks increasing constantly, and its level of internationalization become higher. This paper relies on Dunning's eclectic theory (OLI Model) as a framework to explain the motivators of transnational operation of Chinese commercial banks. Empirical results show that: profitability and international...
Based on the hypothesis of rational decision and take sintering ore blending problem of an iron & steel company as example, the paper firstly formulated the optimizing ore blending problem as a linear programming model under the goal of minimizing the internal material price and market material price, respectively. Then it numerically simulated the dynamic enterprises' internal cost assessing...
The effect of foreign investment on six pollutants such as industrial polluted water, and sulfur dioxide is investigated with the regression model. The result shows that there isn't significantly negative correlation between the FDI and pollution emission, which is contrary to the popular hypothesis so called pollution haven. The environmental effect of FDI notably varies among different regions,...
The influence of regional culture and values on the Chinese human resource market has been steadily increasing, but unconsciously. In recent years scholars have studied a variety of phenomena that imply a shift-away from classical explanations of talent flow and human resource patterns. This has led to the coining of some new terms and concepts, such as "Ant Tribe". This tendency towards...
The literatures related to the price competition between private label (PL) and manufacturer brand are extremely fewer. Based on the Hotelling differentiation model, in the channel structure of the same manufacturer providing products for PL retailer and another retailer selling brand manufacturer, we established the price game model among two retailers and a manufacturer, discussed equilibrium problem...
Operational risk is the risk of loss resulting from inadequate or failed internal processes, people and systems or from external events. It is difficult to model and measure operational risk of bank. The Bayesian network has a great deal of advantage in Modeling and measuring Operational Risk, which is induced by uncertain elements in a complicated system. After review operational risk of bank and...
Nowadays, more and more large IT projects need to unit several entities to accomplish together, which forms project-oriented and geographically distributed virtual organizations and leads to new distributed risks. This article first gives a definition of the distributed IT project (DITPs), then based on the literature, studies the risk characteristics, risk scope, risk factors of DITPs, and finally...
The extension method based on entropy weight is a new safety evaluation method. Entropy weight, which is an objective weight, was ascertained by entropy theory. As a result, the subjectivity in ascertaining the weights of more factors in lower hierarchy was avoided. The comprehensive correlative degree was taken as the evaluation criteria in this method. Therefore the subjectivity of evaluation model...
Consider a two level supply chain consisting of a supplier and a retailer which faces a stochastic demand influenced by retailer's sales effort. Before the sales season, the retailer has to decide both the ordering quantity and the level of the sales promotion at the same time. We first analyze the reason why the traditional revenue-sharing contract can't coordination the decentralized supply chain,...
In the paper, some relative research theory and calculation methods for the river ecological basic flow both at home and abroad have been summed up, and then, considering the actual conditions of Sushui River, the function of the river reach is determined. The ecological basic flow of the river in different periods has been quantitatively researched with Tennant and the minimum monthly average flow...
Supply chain risk is dynamic and conductivity. The process of supply chain risk conduction has the characteristic of self-organizing. The dissipation characteristic, cooperation characteristic and coupling characteristic in the process of supply chain risk conduction are discussed in detail based on the self-organization theory, which can help to take precautions against supply chain risk, improve...
Urban forestry is the core resource used to achieve a virtuous cycle of urban ecosystems and the main subject of urban life support systems. Natural disasters appear in characteristics of high frequency, intensity, and often result in huge losses in their area of destruction. Therefore, the situation requires real-time, accurate and dynamic monitoring, which is an important guarantee for maintaining...
Search engine has become an important daily network application tool to search information. As well-known search engine enterprises, the competitiveness of Baidu and Google is reflected in the financial statements. This paper analyzes competitiveness of Baidu and Google by financial analysis method from five aspects, including liquidity, solvency, operation efficiency, profitability and technological...
This paper considers the problem of how to reduce communication cost over threshold monitoring in distributed system. An Event-based Threshold Dynamically Assign (ETDA) method is proposed in this paper, which considers the situation in reality that the data distribution in remote monitor nodes changes dynamically. Therefore, we set different threshold value in each remote monitor node based on their...
