This paper deduces the conception of mining information model from Building Information Model. It also discusses the content and structure of mining information model, and emphasizes lifecycle management in mine construction. Furthermore, it analyzes the activities in each of phases: planning, design, construction, production and ending based-on mining information model. Finally, it illustrates that...
In the management of land resources, reasonably controlling the amount of land use and making the land resources used intensively is an important measure to implement the dustainable development of land resources. Standing on the land use conditions of land resources, this article considers the business of examining land use as the main line. According to the problems which are possiblely existing...
Although resource-centered and capability-centered network manufacturing alliance has been paid attention at home and abroad, its success rate is low. Non-homogeneous, multi-stage and dynamic game theory is one kind of advanced research methods, but it never be used in studying coordination model to improve the success rate of network manufacturing alliance. On the basis of this dynamic and systematic...
With international practice and needs of business own development, it's has become more and more common to carry out EPC project in enterprises' contract. Comparing with the traditional patterns of contract, the owners will not involve in the specific process of project in EPC model, so the decision risk of the owners is increased. Through analyzing of EPC contract model, to the ambiguity and uncertainty...
To meet the requirements for being geared to the international standards and to meet the demand for self-development of an enterprise, it becomes more and more common for an enterprise to execute EPC projects. The EPC model compares with the traditional contract model, the risk of general contactor is the biggest undoubtedly. Through the analysis of the EPC model to determine the risk source and loss...
SPC is the actual implementer of PFI project, but SPC itself usually has no ability of development. It will make widely use of various agents in the process of project development, which has greatly increased the complexity of implementation of project. To evaluate the implementation process of project by phase and real-time can become effective tool of SPC to help it realize the project well. From...
Based on the present situation of railway design quality, an evaluation index system of railway design quality is setup, and multiple fuzzy comprehensive evaluation method is used to evaluate railway design quality. Then, an empirical analysis is carried on a railway. The results showed that the index system and evaluation method has a strong feasibility and operability. It will be widely popularized...
One of the most important phases in business-to-business-based electronic construction bid is the process of bidding decision-making module whose operating optimization is considered to be the foundation of implementing the integration of B2B-based bid mode. Strategies facilitating the optimization of E-bidding are demonstrated in this paper: in order to utilize the efficiency and effectiveness both...
There are two main quotation mode in current bidding, which are without base price and compound base price. Bidders should bid accurately and reasonably to win a bid. Based on game theory and the characteristics in bidding, this paper constructed bidding price game model of without base price and bidding price game model of compound base price to provide evidence for bidding decision. Relevant factors...
Architectural design (AD) proposals selection is one of the most crucial procedures before the final construction of a project. To make decisions, the jury members need to assess the design proposals considering various criteria, such as function, appearance, sustainability, context, economics, and so on. A model based on fuzzy analytic hierarchy process (FAHP) is proposed to select the most appropriate...
When the computation of project duration, the unascertained factor of project duration is leave out in traditional PERT network. And the computing result is a determine value. In this paper, the unascertained number algorithm is introduced in order to discuss the uncertainty in project network. And the project duration is contract with the credence. Firstly, the uncertainty of project duration is...
This paper examined strategic technology alliance from the perspective of technological catching-up in emerging economies. We developed a conceptual model for describing the phenomenon that strategic technology alliance can effectively improve the absorptive capacity for firms in emerging economies. We used a case study of housing industrialization strategic technology alliance in China to explore...
This paper examined the social network construction mode based on connected network component under dynamic alliance environment. We assume that firms in one industry participant in alliances dynamically and simulation results show how the alliance network factors influence the social network information sharing performance. Four propositions in a long-term and no extreme value context are built:...
With international practice and needs of business own development, it' s has become more and more common to carry out EPC project general contract in enterprises' contract. The EPC model covers basically the entire project construction process and comparing with the traditional contract model, the risk of general contactor is the biggest undoubtedly. To the ambiguity and uncertainty of risk assessment...
Project risk element transmission theory puts forward a new idea of research on project risk management. This paper combined with state transfer diagram, analysed enterprise multi-project management, made concrete exposition on the thought of project chain with different risk element kinds. A tetrahedral structure model of enterprise project chain risk element transmission and controlling mechanism...
Diagnosability is a crucial property that determines at design stage how accurate any diagnosis algorithm can be on a partially observable system. Recent work on diagnosability has generalized fault event case to pattern case, which can describe more general objectives for diagnosis problem, but based on global model and global twin plant construction. In this paper, we propose an original framework...
A suitable project manager has a very important promoting role to play in the smooth and successful implementation of the project. This paper attempts to set up a comprehensive evaluation model of project manager candidates and evaluation of the qualifications of the candidates for a construction project by using principles of fuzzy mathematics. Empirical research shows that fuzzy mathematical methods...
Highway construction progress risks not only influence the development of an enterprise, but also have a great impact on the national overall strength. This paper attempts to analyze construction progress risks of highway qualitatively and quantitatively from the perspective of theory and practice. The weight of each progress risk index could be obtained by using the analytic hierarchy process and...
Opinion mining is becoming one of the research highlights and the control of internet public opinion is also hot research topic. A new kind of tree which is called opinion tree has been proposed and defined. The flexible opinion mining model based on opinion tree is created and thus coarse-grained, medium-size and fine-grained (three different granularities) opinion mining are all realized in one...
Evaluation of community commerce building is fundamental to work out the strategy for the development of community commerce, guiding the business community to make healthy and coordinated development. This paper firstly introduces the significance and principles for establishing evaluation index system. According to the evaluation norms of the national model of community commerce, this paper further...
