Now the state norms of the bridge falsework have not yet been promulgated, and falsework design theory is seriously inadequate, which make it hard to guarantee the stability of bridge falsework and results in a series of bridge falsework collapse accidents in recent years. Based on the test of overall stability of the bridge falsework, AHP is used to give scoring weight to effect factors-the scoring...
Under the analysis of the present situation of urban roads at home and abroad, the paper reviews the development of tripper guiding information system, traffic-flow distribution model and route choice model. Then it has three multi-attribute decision-making model based on the influence factors of tripper route choice and uncertainty theories, in order to analyze the decision-making process of tripper...
The traditional transmission network planning is confined to a single-level construction, while the actual transmission network planning needs to take into account the time factor, namely how to build the best route to network planning. The difficulty of the multi-stage planning is the transition between stages, with the later stages of the decision-making depending on earlier stages of decision-making...
The rational site selection of thermal power plant will impact the economic operation and sustainable development directly. On the basis of construction of index system for evaluating thermal power plant site selection, the method of rough sets is applied to obtain the index weights, which only lie on the system potential information. Through the method of expert group decision-making, the quantitative...
To achieve the goals of: (1) reflecting the value information of resource flows and points to the key areas for improvement in an enterprise, (2) providing effective decision-making in environmental and resource management, and (3) showing the direction of the enterprise's sustainable development, this paper develops the resource flow equation which includes three kinds of indicators: (1) resource...
With the coming era of intellectual economy, compensation management has become more and more important in business management. How to manage compensation management safely and efficiently has been the focus of attention in modern enterprise. This paper, which starts with risk recognition of compensation management in modern enterprise, analyzes main sources of compensation management risk and offers...
Due to the remarkable ecological value, the plateau freshwater lakes of Yunnan play the important supporting roles in the regional economic and social development. The pollution and the ecological degradation of the plateau lakes have become increasingly prominent since 1990s. Consequently, the lake basins are facing serious challenges in the sustainable development. Promoting sustainable development...
The relationship between parameter configurations of mechanical products are the main design rules that affect their work performance and the major factor that optimize product structure. However, the actual relationship of parameter configurations can't be gotten directly in the design specifications or the manual. Physical experimental methods are difficult to implement due to long cycle and high...
Under the stress of inflation, company's capital investment budget is affected by the increase of price. On purpose of making scientific investment decisions, the company must take into account the impact of inflation. This paper attempts to show the impact of inflation on company's investment decision making. With the aim to provide direct and scientific data to illustrate the influence of inflation,...
The nonreversibility of strategic investment and nondeterminacy of information acquired from inner and outer environment put importance on the strategic choice timing. Whether the conversion timing is chosen correctly or not has become one of the key factors influencing the conversion performance. At first, this paper analyzes the influencing factors and random characters of strategic choice timing,...
According to the characters of the third-party logistics enterprise, the article constructs an index system of performance evaluation that consists of four classification criteria which includes the financial performance, operational procedures, learning and innovation and customer relationship management. The index weights are determined by combining analytic hierarchy process (AHP) method and principal...
The Supply Hub could be applied to the downstream in the supply chain. The research showed that Supply Hub could integrate supply chain system in the corresponding stages, strengthen information sharing and supply chain coordination. The paper studied a supply chain with multiple manufacturers and multiple retailers dealing with a single product, established models of supply chains with and without...
In recent years, the GMS countries are becoming the hot point of the direct investment. The total volume of investment from Yunnan grows increasingly. But in the meanwhile, the risk of the host country is hindering the investing countries' positivity. The article takes the SME of Yunnan for example, focusing on two sides, one is the forewarning system, another is the management system, and combining...
Combined with engineering example, this paper utilizes the Monte Carlo method in network planning, calculates the probability of project completion or completion risk for specific planned construction period.
In recent years, there have been increasing researches on the irrational, subjective and perceptual aspects of strategic management, indicating the influence of perceptual factors such as value, emotion and feelings on strategic decision-making. Based on a rational perspective, current mental model is divided into belief and knowledge and is regarded as a mechanism to explain human perception, decision-making...
Based on the principle of Mahalanobis distance discriminant analysis, the discrimination of influential degree of the different index to optimization of supporting programs for deep foundation pit is taken into account, using the weights obtained by the analytic hierarchy process to modify the Mahalanobis distance, by the new calculation method of covariance matrix, the weighted distance discreminant...
In multi-attribute group decision making, The weights of experts directly affect group decision making. In this paper, from an objective point of view, An adjustment method of experts' weights is proposed on the basis of concrete judgement abilities of experts. Furthermore, a new uncertain multi-attribute group decision method is put forward, Finally, an example verifies its validity.
The assessment of River water quality is the basis of water pollution control, environmental management and environment planning. In this paper, combining analytical hierarchy process(AHP) with fuzzy mathematics, we make a synthetic assessment of river water quality, the indicator system of fuzzy synthetic assessment of rive water quality is established. AHP is used to determine the weight of indicators...
Recently, the traditional flea markets for college students have a lot of flaws and defects. The existing C2C E-Commerce Web sites have not provided a stage for college students, who are in the ranks of the special groups. This paper devotes to create an on-line flea market which is faced with the Higher Education District focusing on college students. Firstly, it investigates the satisfaction of...
Material procurement is the very first link in the course of construction project, which relates to project cost, quality, and time limit and so on. Therefore, the selection of supplier is particularly important. In this paper, a two-stage model of supplier selection in project has been constructed by rough set and multi-objective liner programming based approach. The application of rough set based...
