In this work, we propose initial steps in the first systems safety approach that coordinates the control and safety systems through a common metric (a Safeness Index) and develop a controller formulation that incorporates this index. Specifically, this work presents an economic model predictive control (EMPC) scheme that utilizes a Safeness Index function as a hard constraint to define a safe region...
Credit evaluation of customer is an important task for gas companies to achieve marketing management, and is of great significance to improve the economic efficiency of enterprises. By analyzing various factors influencing gas customer credit, a gas customer credit index hierarchy is established. Then, based on the credit index hierarchy, this paper proposes a hybrid credit evaluation method by cluster...
This study intends to import the triple bottom line (TBL) model. In light of sustainable business process, in which the movement of the Global 100 Index affects economic benefits, corporations must include environmental and social costs at the optimal time based on the best economic benefits that match the corresponding Global 100 Index.

Maintaining and improving safety has always been the most important thing for civil aviation. Safety investment is an important material guarantee and basis for civil aviation safety. Insufficient investment in safety and irrational structure of safety investment are the causes of accidents in civil aviation. A review of recent research articles related to safety investment was presented and the research...
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,...
Urban rail transit has been selected as the research object for this paper. Firstly, an index system has been established to evaluate the passengers' satisfaction and loyalty from the perspectives of service quality, passenger satisfaction and loyalty. Secondly, a passenger satisfaction and loyalty evaluation questionnaire for the urban rail transit service quality has been designed and a survey has...
Since China adopted the policy of fully opening retail market at the end of 2004, the entrance of multinational retail enterprises brought the reality and potential impact on the domestic retail such as structure, controlling power and competitiveness. From the perspective of industrial safety concept, combined with the mature DEA model, this paper focus on analyzing the security of the four kinds...
In order to clarify the impact of financial subsidies on residents' travel choice, the paper used the method of multivariate logistic regression to establish residents travel mode choice. And cost-effectiveness analysis was carried out on the traveling choice of bus, with the benefit cost ratio instead of the benefit function in traditional logit model. Taking Beijing for case study, the paper calculates...
With the development of comprehensive transportation system, the competition among various harbors becomes more intense. The paper proposes the evaluation method of container harbor's competition based on the discrete mutation — topsis matter element and establishes a model against the actual harbor's presentation and gives a solution. By using this method to build the port competitiveness evaluation...
Waterway transportation accidents may cause great economic losses, casualties and environmental pollution. Traditional comprehensive index method is used to conduct safety assessment with fixed values, and can't reflect the randomness and uncertainty of risk. This paper analyzes several typical factors influencing the Yangtze River waterway transportation safety to identify four indexes for waterway...
In recent years the view of Jinggangshan is enchanting by its unique mountainous landscape and revolutionary cradle, which offers many attractions for tourists at home and abroad. Develop continuously along with the tourism industry, the blind development of land resources in the drive for economic interests has been leading to serious degradation of its land ecosystem mountainous and causing serious...
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...
In order to control the key point of accidents during bridge construction, a number of major risk factors are recognized from the point of the insecure elements of human beings and the insecure status of objects, and a risk assessment index system of bridge construction stage is created based on these risk factors; so given the uncertainty and fuzziness of the risk factors, the risk assessment of...
With the rapid development of high — speed railways, more and more people choose high-speed railways while traveling. The average travel cost is one index to evaluate its service quality. Through analyzing the factors influencing travelers' average travel cost, the percentage of A-type (300 km per hour) and B-type (250km per hour) trains and their distribution, this text is instructive for making...
The most fundamental means of maintaining mechanical safety is to systematically carry out safety design and analysis in the mechanical design process. The fuzzy comprehensive evaluation method is to take the advantages of the level analytic hierarchy process and fuzzy comprehensive evaluation method. Firstly, the evaluation index system is divided into ladder level structure, calculated the index...
Under the background of globalization, the basic function of resource supply and ecological environment is becoming more and more for the sustainable development of the industry itself, and its impact on the industry's own safety as much as other economic activities. In this paper, the influences of resource supply and ecological environment are discussed for industrial safety based on review of the...
Safety warning management is a new method of safety management in coal mine, which helps to ease the prevention shortage and change passive situation facing safety accident. The object on early warning management is greatly important for warning management, which affecting warning results seriously. This paper has constructed safety warning management factors system based on literature summary, expert...
The situation of the safety production of enterprise is very severe in China due to the insufficient safety investment. The accounting has unique effect if using it to manage the safety investment activity. However, the accounting function in safety investment of enterprise in China does not effectively mobilized. Based on the factors, Current situation of accounting of safety investment of enterprise...
This paper applies fuzzy clustering into clustering processing emergency rescue route according to pertinent indexes. With MATLAB software as platform to perform simulation experiment, paper finally gets dynamic clustering figure by setting up different confidence level λ. This paper aims at simplifying route choice decision to establish foundation to search shortest path.
The purpose of this paper is to build an available model and framework from GRNN neural network to evaluation the impact of FDI (Foreign Direct Investment) on China's economy security. The method used in the study is known as factor analysis and GRNN neural network analysis. Examining 20 years' (from 1990 to 2009) data, we set up an index evaluation system. We then analyze Chinese 20 years economy...
