The development of urban economy is facing the challenges from the natural environment. And how to realize the continuous development of urban economy and to make sure of the proper recycling between the nature, environment and human beings has become the core problem of modern urban economy development. Therefore, Dalian, a very famous Chinese seaside city, creates such a model, which forms a complete...
"Digital Ocean" is essentially a virtual ocean world which is composed of massive, multi-resolution, multi-temporal, multi-space marine monitoring and data analysis algorithms and models. "Digital Ocean" will promote a more intelligent way which people exploit and make use of the ocean, thus guarantee the sustainable development of the sea. This thesis conducts a research to the...
According to the requirements analysis of highway project management information system, a technical scheme using GIS (geographical information system) technology was put forward. A study method was adopted combining GIS technology and large commercial database management skills and this system was developed. Highway project management information system was divided into seven subsystems. It adopted...
The past decade has witnessed a rapid development of the international construction market. This research aims to investigate top Chinese contractors' surplus distribution created by Value Engineering (VE). During the past few decades, VE approach has been widely used in the area of construction, which focuses on the lowest lifecycle cost consistent with performance, quality and reliability. Only...
Engineering quality has always been an important objective of the project, however, at present, in China's market economy conditions, high-quality engineering requires the effective supervision of the engineer. In order to increase the probability of contractor's guarantee of quality, this paper makes some hypotheses, and based on these hypotheses, a static game model among engineer and contractor...
This paper introduced a construction for LDPC codes over GF(q) based on filling with circulant matrices. After expanded the cycles in the check matrix by filling circulant matrices, the error-correcting performance of the codes can be improved with a low constructing complexity. The simulation results shows that the codes constructed can achieve better error-correcting performance.
This paper establishes a model of equivalent price settlement (time-dependent) in engineering construction contracts brought by the principle of time value of capital and completes a sensitivity analysis to the value realization of the contract price from three aspects of the changes in rate of return on investments, settlement frequency and cascade reduced settlement of the project. The calculating...
As the impending of 2010 Shanghai World-expo, it has been becoming a hot topic, how to manage huge volume of, and heterogeneous information efficiently and in security. In this paper, the definition of digital world-expo is first given. Then, we present a novel idea on general system of digital world-expo, in the interest of providing reliable and consistent service oriented toward trust and authorization...
Increasing salary costs, management efficiency concern, and economic globalization provide a strong incentive for enterprise's information system construction. This paper describes the construction of the auxiliary material order and warehousing management information system in the case of the overall information development at the X cigarette factory, for the purpose of achieving sharing of information...
As one of the significant reform methods to improve the management level of government investment project, agent-construction system has been applied in many places. During the process of agent construction, agent assumes considerable risk. This paper identifies the main risks of agent. Based on the analytic hierarchy process method, the main risk and relative influence factors are analyzed and evaluated...
Government investment projects play important roles in the economy of China. As one of the significant reform methods, agent-construction system is in favor for assuring the specialized management and overcoming deficiencies exit in public projects. However, the current risk allocation in agent-construction system is unreasonable and partly results in low performance of this system. The different...
It is important issue for the study of method of the project risk assessment. The quantitative method is used to resolve construction project risk assessment in this paper. Firstly, the study of project risk management and risk assessment is made a review. Secondly, the project risk management systematic framework is constructed, which include five purchases: risk identification, risk assessment,...
The investment risk at various stages in power generation project is a complex and dynamic system. There're many uncertainty information in the process of investment. By analyzing the cost risks, time risks, environmental policy risks, financial risks and market risks in the preconstruction, construction and operating period of power generation project, a dynamic risk evaluating model which considered...
Constructing and managing an information system (IS) is a highly complex and difficult system project. It is a problem which is needed to be solved that how to measure the value which is brought to the enterprise by IS and how to make IS bring more value to enterprise. The research's emphases is the IS in enterprise. It will focus on the measurement of value the IS brings to the enterprise even to...
The calculation and exhibition of risk management techniques will be more efficient and flexible by business intelligence(BI) tools. However, there are few researches on BI for securities companies' risk management(SCRM). After reviewing the business and technique problems, this paper analyzed the BI system framework of SCRM and discussed key issues of BI system construction. It also addressed the...
This paper combines the rough set (RS) theory and support vector machine (SVM), and making best use of the attribute reduction characteristic of RS theory catches the main attribute of the research subjects, and it uses SVM to make prediction model, and applies this method to construction safety pre-warning. The experiment results show that the method is viable, which makes a useful exploration research...
On the basis of necessity analysis of risk identification in large-sized mining shaft construction project, this article researches from the aspects of goal, method and procedure of risk identification and constructs a procedure-oriented large- sized mining shaft construction project risk identification implementation system according to the characteristics of shaft construction project in large-sized...
With the increase of the financial crimes in Chinese commercial banks, to measure the operational risks and build the comprehensive framework of operational risk management become increasingly urgent. In present study, Bayesian inference, which combines the expert opinions and the dynamic risk factors, has been applied to the measurement of the operational risk based on its construction, initiation,...
Chinese government has been propagandizing energy- efficient residential buildings for more than 20 years, but the progress is unfortunately not satisfactorily smooth. One and most important reason is the lack of incentives to energy-efficient residence for both consumers and developers. This paper discusses the features of the residence market at present in China, analyzes variables influencing consumers'...
Since the construction supervisor was introduced as a third-party in Chinese construction projects decades ago, more and more third-parties are needed by construction project owners. But there is not a universal evaluation method for third-party management performance in construction projects, and the values of third-party management are often omitted and third-party's role in current Chinese construction...
