Wargaming system is an effective method for emergency management. The evaluation methods are the important parts of the system. First, the essential features and principles of wargaming system are explained. Then, the evaluation methods of wargaming system are analyzed, and four main types of evaluation methods are described in detail, such as the movement type, position type, effect type and impression...
Communicating information on the environmental status of water, air and other parameters to the policy makers and the public at large is by indices. The US Environmental Protection Agency (EPA) formulated a uniform Air Quality Index (AQI), for the use of state and local agencies but there has been no general acceptance of the method. Many countries have devised their own methods for describing air...
The assessment of urban seismic vulnerability should always account for the robustness and uncertainty of the used methods. This paper presents a comparison on preliminary evaluations of expected damage within an urban district of the city of Oran (Algeria) in order to exploit a non-dedicated set of data issued from a technical survey of the buildings. Three different methods are used (GNDT 2; RISK-UE...
The auxiliary company decision-making having introduced that Anshan supplies electricity mainly supports the main body of a book to apply content such as background, construction target, scheme and technology characteristic having the problem, solving systematically. But the model builds system owing to that the country electrified wire netting SG-CIM model composes in reply multi-level Cube, apply...
In order to solve the existent problems of incomplete and ambiguous information during the evaluation on the multiple constraints factors of city underground space development and utilization, this paper applies analytic hierarchy process and fuzzy comprehensive evaluation method to construct the comprehensive evaluation index system of the multiple constraint factors of city underground space development...
The seismic risk is functioned by the probability of seismic intensity and vulnerability of wealth (such as life, property etc.) in a specific space and time domain. The assessment of vulnerability is essential for the post earthquake loss estimation. The practical vulnerability of a building is decided by not only the building type and its anti-earthquake ability in a certain seismic intensity, but...
In this paper we propose to study urban mobility by using mobile phone data. New metrics to estimate the basic properties of displacements are defined: mobility intensity (speed-like measure) and uncertainty. Mobile phone data from technical GSM network probes were used in the study. A spatiotemporal analysis of antennas activity and user mobility in Paris region is proposed in order to validate these...
In accordance with the Hybrid multi-attribute decision making problem with attribute value of several interval uncertainty data information, decision making method is presented. First, the paper gives three interval type representations of attribute value, then, makes use of set pair, convert interval type attribute value into the presentation of connection number and construct the connection degree...
Assessment of flood risk is important to flood disaster forewarning and decision management. However, there are many uncertainty factors that influence flood risk assessment. In order to solve this problem, this paper proposes an information fusion method based on DS-AHP (Dempster-Shafer and Analytic Hierarchy Process) to deal with uncertainty information, and fuzzy set theory and GIS methods are...
The data provenance describes the producing of data and evolves with the time. It has many application fields, such as evaluation of data quality, audit trail, replication recipes, data citation, etc. This paper emphasizes on describing about how data is generated and evolves with time going on, and gives an example of Data Provenance in Economical Database Design to describe the application of data...
Set Pair Analysis (SPA) is a new methodology to describe and process the system uncertainty and has been applied in many areas recently. In view of the uncertainty and complexity in the process of urban ecosystem health evaluation, the paper introduced SPA theory and established an evaluation model. In the model, identity-discrepancy-contrary connection degree formula embodied certainties and uncertainties...
In the economic globalization background, the scope of foreign direct investment (FDI) is more and more bigger, and the economic impact on countries and regions is more and more far reaching. Therefore, the environmental evaluation of foreign direct investment has become a very important topic, but existing environment evaluation method of foreign direct investment is very hard to unify objective...
Ecosystem health is the prerequisite for ecosystem service function. Assessment reflecting the trends of urban ecosystem health can improve 'information for decision making' on sustainability. Because urban areas are an advanced man-made complex ecosystem consisted of nature, society and economy, the key of urban ecosystem health assessment is to set suitable model for resolving the uncertainty of...
The mass rapid transit system is essential both to rational utilization of the economical resource and optimization of overall arrangement of urban land use. Choice models diffusely used in China now are largely based on the certain values which fall short of the practice. In this passage, grey numbers are used to estimate the practical situation and the set pair analysis is introduced to determine...
The excessive increase in savings of Chinese households and the savings motive of urban households who hold most of savings have attracted great attention of academic community as well as policy maker in recent years. Based on the theory of precautionary savings, this paper directly introduces the future uncertainty into the savings models as an independent variable, moreover, simultaneously take...
