In order to improve the electric car battery safety early warning ability and decrease the safe accident of electric vehicle charging, the electric vehicle charging safety factors are analyzed, the security early warning index selection ways and methods are studied, and a security early warning evaluation index system is set, the evaluation method of weight for safety index is discussed. Besides,...
Evaluating security threat status is very important in network security management and analysis. Aquantitative hierarchical threat evaluation model is developed in this paper to evaluate security threat status of a computer network system and the computational method is developed based on the structure of the network and the importance of services and hosts. The evaluation policy from bottom to top...
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...
Risk evaluating and ranking model of notched blasting flyrock in the tall and big chimney blasting demolition project based on unascertained measure theory was built up. Considering the eleven factors of chimney blasting flyrock, the unascertained measure function of influenced factors was established according to the measured data and engineering experience. The model was separately analyzed in the...
As improving the quality of the construction engineering project is very important for construction industry, in this paper, we propose a fuzzy AHP based approach to evaluate the construction engineering project quality. To cover all influencing factors of the proposed problem, three parts are contained, including 1) Building safety performance, 2) Building utilization function and 3) Construction...
This paper focuses on the problem of college physical teaching quality evaluation, which is of great importance in modern education. Firstly, we propose an index system for evaluating the quality of college physical teaching, and it can cover many influencing factors of college physical teaching quality estimating. Secondly, we propose a fuzzy AHP based college physical teaching quality evaluation...
This research identifies a number of key factors related to online consumer trust and establishes a model based on the System Dynamic method to find out the relationships between these factors and trust. This paper provides several contributions. Firstly it reviews the previous works of online trust and identifies the major online trust building factors which mainly consists of business factors, consumer...
It is the basis for making analysis of the status quo and implementing effectively road traffic safety management to launch the evaluation for regional road traffic safety, while the construction of scientific and effective evaluation system is the prerequisite of carrying out the evaluation. In order to provide a method for the evaluation for regional road traffic safety, a grey integrated evaluation...
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...
To vary and improve risk assessment method of port facility security, a new risk assessment approach based on a comprehensive model (DHGF model) is developed, which integrates the Delphi method, the analytic hierarchy process (AHP), grey theory and fuzzy evaluation method. A comprehensive evaluation to the target port facility on security is obtained from qualitative analysis to quantitative analysis...
To evaluate accurately the drilling status that affect safety of oil well drilling and reduce the occurrence rate of drilling accidents, this paper firstly analyzes the factors which affect the safety of drilling to determine the drilling safety evaluation indexes. Then it adopts analytic hierarchy process to construct a drilling safety evaluation model, and calculates the influence weights of indexes...
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 more effectively assess the safety risk of a wind farm project, the evaluation indicators in the life cycle of a project can be divided into quality index, cost index, time index, security index, and sustainable development index. By combining the qualitative with quantitative, the model of principal component analysis (PCA) of the life cycle indicators was established, which can reflect...
Contractor safety is the key to success for construction projects, the contractor safety goals and performance evaluation system has become the important task of safety management of current building construction. This paper based on experts linguistic assessment and multi-granularity language fusion method of qualitative indexes to evaluate and rational quantification, through the C2R DEA model and...
This paper makes a system research on the Animation derivatives evaluation process and methods and analyzes the main problems of design evaluation, meanwhile putting forward of constraint condition Animation derivatives evaluation system and model based on cost control and function. From three dimensions it devises nine secondary indexes and forty four triple the evaluation index system, combining...
In order to establish a set of scientific rural credit cooperatives risk evaluation system, and fore-control risks, this paper selects 15 indexes to constructs the rural credit cooperatives risk evaluation index system, through the analytic hierarchy process and fuzzy comprehensive evaluation method of these indicators, The rural credit cooperatives risk evaluation index model is built, and according...
The “supply positioning model” in modern supply chain management theories is to direct decision maker to make sure the purchasing emphases and product supply strategy by analyzing the different characteristics, influence and risk of each product. The paper puts forward to apply the “supply positioning model” to equipment material support. On the foundation of Kraljic's matrix, “level of inventory...
With the increasing complexity in civil engineering projects, the multi-program group has become a large-scale system problem. Three analysis models for safety evaluation are discussed in this paper: safety comprehensive analysis model, safety performance analysis model and safety contribution-rate model. Then the safety indexes of these models are deduced and build up respectively. Furthermore, the...
Based on the unascertained theory, the paper elaborated exhaustively the construction process of the unascertained measure model. Combined with the unascertained measure model, the factors affecting coal-mine safety are analyzed and evaluated. According to the reality of Bofang coal-mine safety management, we can collect the measured data, determine the safety evaluation index, calculate for example...
To achieve food safety, risk control in food supply chain is required. Supplier evaluation and selection is one important process for food supply chain. This paper establishes a system based on risk control and integrates the DEA-based objective method and the ANP-based subjective method into a new ANP&DEA-based decision model for supplier evaluation. The paper explains the mathematical analysis...
