Public safety has been discussed for many years, but how to use and understand crime data is still difficult. Limitations of previous research were mainly restricted by technology. The significant technological advance since last century provided a tool for researchers to compute large amount of data and complicate models while shrinking process time too. This research tried to combine results from...
Beichen district of Tianjin, located in the important node of Beijing-Tianjin golden corridor and high-tech industry area of Jingjintang region, has strong industrial foundations, while it is still faced with the problems that traditional industries account for high proportion of the industrial structure, inefficient use of industrial land, lack of enterprise innovation ability and shortage of resources,...
With the rapid economic development, the inland navigational environment has undergone tremendous changes. Ships are facing with several environmental impacts during the voyage, such as variation of water level, strong waves, poor visibility and so on. The safety issue of inland waterway transportation system (IWTS) confronts significant challenges. This paper identifies the safety critical factors...
Most of the emerging applications for road safety and traffic management rely on the frequent exchange of awareness messages among vehicles. Unfortunately, the 802.11 protocol poorly behaves under congested scenarios and cannot guarantee the reliability and timeliness demands of massively transmitted broadcast messages, leading to the severe degradation of safety. Recently, there has been a consensus...
Safety culture construction has significant impact on fire prevention in oilfield. Reasonable evaluation index system should be set up to evaluate the state and quality of safety culture construction in oilfield enterprise teams while further study should be taken and validated on spot. Framework of safety culture construction in Oilfield enterprise teams was put up. By SMART principle and occupation...
According to the characteristics of construction project, the risk evaluation of complicated construction project is converted into the evaluation of four indexes including duration risk, cost risk, quality risk and safety risk. Establishing the fuzzy and grey correlation analysis model with the combination of the fuzzy theory and the grey correlation theory, fuzzing the judgment of specialists on...
This paper takes historical data from national poverty counties to analyze the correlation between the audit quality of anti-poverty fund and its efficiency. The study finds: there is a significant positive correlation between illegal amount found, information submitted and poverty alleviation efficiency, yet that with cases transferred to the relevant departments is not notable. Therefore, this article...
The safety evaluation of petroleum resources based on Grey Correlation-TOPSIS is simple but practical, scientific and reasonable with certain application value. The safety evaluation of petroleum resources based on Grey Correlation-TOPSIS applies approximation coefficient of grey correlation for evaluating the safety degree of petroleum resources and effectively overcomes the shortcomings that the...
It is difficult to evaluate the maintainability in design phase obviously. The system level and indicators selecting procedure are given in this paper, and the experience & data based synthetic evaluation method of system maintainability is structured to find out the key component and improving direction, providing a scientific and effective solution for maintainability evaluation. Subsequently,...
The process of choosing appropriate supply chain (SC) performance measures is difficult due to the complexity of these systems. Most of the organisations measure their internal performance but they are unable to benchmark it. The performance of the organisation can be only improved if the SC performance of the one organisation is compared with the supply chain performance of the other organisations...
Artificial creatures need an intelligent behavior selection method to be used as an intermediate interface for natural interaction with users. For this purpose, the mechanisms of thought were proposed based on the probability and the degree of consideration. However, they were time-consuming when applying to an intelligent artificial creature with large numbers of wills, contexts and behaviors. Moreover,...
The occurrence of accident is influenced by multiple factors, so in the process of accident warning model construction, we should take full account of the relationships between all of the factors and the accident and the roles that these factors played in the accident. This paper constructs an accident warning model by employing the entropy weight and extension theory. On one hand, this model employs...
This paper use the gray single-level evaluation evaluate coal enterprises' security condition with a gray theory, let the coal enterprise's evaluation be more scientific and more realistic and provide a reference for the safe appraisal of coal enterprise.
Much research has been done on construction safety cost. However it is always on a qualitative level, little quantitative research has been done, especially on the safety cost of water conservancy construction project. In this paper, by the combined use of grey correlation model and optimal safety cost model which is under dialectical understanding, a dynamic management model on the safety cost of...
With the development of mining, mine environmental quality evaluation has become an urgent issue. This article takes the influence of the mining construction situation, natural ecological environment and social economy environment as the indicators of the mining environment assessment, and it also takes into account the relationship among resources, environment, social-economic. Then, using rank correlation...
The earnings of the listed company decides its value, measuring the quality condition of earnings synthetically is conducive to reflect the real state of profitability more objectively. Difference exists in the measurement of earnings quality for different industries, take manufacturing industry for example, this article will use factor analysis to construct a index system to measure the quality of...
This paper introduces the construction of highway management standardization and the necessity, also introduced the research status and research contents of highway construction, researched standardized data processing methods of analysis and research. The standardized effect evaluation method there are Min - Max standardization method, More direct comparison analysis, Comprehensive point rating method,...
In order to actually reflect the situation of trunk road service, the paper puts forward the definition and connotation of trunk road service oriented by user demand on the basis of Maslow's needing theory, selects 16 indexes from three aspects of service condition, service environment and service activity on the base of expert experience and related specifications, and sets up evaluating index system...
Middle and small size fault structure is the key geological factor affecting the safety production of DongPang mine field. Finding out development character of middle and small fault structure in DongPang mine field is to provide the geological premise for mining design of coal mine and working face layout. Based on the analysis of real data, 20 factors affecting the development of middle and small...
