20 factors are selected to frame a primary factor set from 38 factors obtained through literature study. The methods of Mean Score and Ranking Agreement Factor are applied to calculate the sorting order and analyze the consistency of market survey data. The results show that 17 factors concerning owner's engineering capabilities, owner's preferences to project construction, project properties, and...
The thesis introduces entropy and dissipative structure theory of thermodynamics into the evolved study of compensation administration system. According to the compensation administration system's dissipative characteristics, entropy model is constructed on the basis of evolving compensation administration system. Through the quantization in terms of entropy, the thesis investigates the evolution...
Data Mining can find out the hidden important information in mass data, whose main purpose is to help decision-makers to look for the potential relevance between the data, to find out neglected elements, and make decision based on these models automatically. This paper, based on the discussion of data mining, analyzes the framework of enterprise decision support system, designs the enterprise decision...
Data Envelopment Analysis (DEA) is a linear programming methodology to measure the efficiency of multiple decision-making units (DMUs) when the production process presents a structure of multiple inputs and outputs. It excludes the subjective factors and has been applied in many areas. This paper is mainly focused on the input-output efficiency appraisal of key industries of Hebei province based on...
Unequal Area Facility Layout Problem (UA-FLP) has been addressed by several methods. However, UA-FLP has only been solved regarding quantitative criteria. Our approach includes subjective features to UA-FLP, which are difficult to take into account with a classical heuristic optimization. For that, an Interactive Genetic Algorithm (IGA) is proposed that allows an interaction between the algorithm...
Secondary school English teaching plays a key role in English education in China, while its current status, especially in the countryside, is not as good as we expected and thus innovation in this field becomes indispensible. This paper analyses a questionnaire research statistics with SPSS 16.0 and tracks down the barriers to innovation in secondary school English teaching in the countryside of China...
It is very important for the military procurement departments to select supplier scientifically. The selection of suppliers has a direct impact on the efficiency of military materials procurement. This paper proposes the gray comprehensive evaluation model based on the analytic hierarchy process and the grey correlation analysis. Firstly, it describes the principle and steps of gray comprehensive...
Along with rapid development of information technology and the Internet, more and more universities begin to pay their attention to web-base teaching and invest heavily on it. But the effectiveness of web-based teaching doesn't achieve the anticipated result. This paper reviews various kinds of influential factors of web-based teaching effectiveness and constructs a two-level framework for effectiveness...
Shortcomings of the traditional chain-like information flow control pattern in supply chain system are analyzed. A net-like information flow control pattern is put forward and the architecture is designed. In the architecture, Combined Scheduling Center (CSC) serves as the information center, the node enterprises in the supply chain could directly exchange data with CSC based on Internet/Intranet...
It has the features of data missing and nonlinear in multi-process manufacturing the quality data, the quality knowledge mining and key parameter decision-making based on CART method is carried out. Then the object data model, implementation method is discussed. At last, an application case in Alumina Ceramic Tube production is given which shows the CART method has strong applicability in multi-process...
The Highway consists of the roads used by vehicles and the other public infrastructure facilities around it that the lack of good management and the poor facilities usually causes the government compensation for damage. In order to solve these situations, we collected lots of cases in the study for conclusions. First, we divide the reasons into 6 categories. There are the factors in rock fall, bridge...
The performance level of customer services (for example, short time for delivery of customer orders and economical service process) in manufacturing enterprises greatly depends on an effective manufacturing planning and control system (MPCS). The hierarchical planning approach of most MPCS may have resulted in critical situations, such as rigidity in the planning structure, complex control system...
An analytical way to reach the best decision is more preferable in many business platforms. In this study, Analytic Hierarchy Process has been applied for evaluating the impact factors of foreign exchange income by tourism market in Henan province. Moreover, the score methodology by specialists and MATLAB software are also used for getting the impact factors' weight scores. The results show that the...
The disassembly sequence decision making for used products is extremely important for recycling and reuse of components. In order to calculate the analysis difficulty of disassembly path in deciding on disassembly sequence of products, a decision-making model of product disassembly sequence with Fuzzy Reasoning Petri Nets (FRPN) is proposed. And then, combined fuzzy reasoning Petri nets with matrix...
Teachers play quite an important role in teaching, and teaching evaluation includes teachers' evaluation. But the traditional teachers evaluation system can not meet the demands of age. So this paper establishes an effective formative evaluation system and applied the AHP theory into this system. Finally, this paper gives an example to demonstrate how to accurately calculate a teacher's teaching ability.
Because of the uncertainty of indexes in the bid evaluation of power equipment, the paper applies TOPSIS analysis method based on AHP to the bid evaluation of power equipment. In accordance with bidding rules of power system equipment, the paper establishes the index system for bid evaluation of power equipment and uses AHP to determine the weight value of each evaluation index. On this basis, combining...
The introduction and rapid growth of social computing into educational practices has encouraged the development of the networked learning through a careful evaluation of the “social nature” of digital applications that implement interaction and collaboration among network users. This evolution is reflected in the Virtual Learning Environments (VLE) systems and supports the progress to online shared...
This paper presents the efficiency measurement model that has been developed based on data envelopment analysis. The model is intended for products produced by organization, optimizes a ratio of multiple weighted outputs to a multiple weighted inputs, where the efficient unit will have a score of one, and the inefficient unit will have a score less than one. The model is simple yet practical in implementation...
Plant location decision is important in supply chain design and optimization. Traditional evaluation of KPIs affecting one plant includes quality's and cost's aspects. Now the competitions between companies have changed to the competition between supply chains. This paper presents a new KPI evaluation system for plant relocation from the viewpoint of the entire supply chain optimization by considering...
The emergency logistics system plays an important role in fighting against diseases and natural disasters. Evaluation of the emergency logistics system provide a basis for system optimization. An evaluation model for emergency logistics system based on hierarchy gray method is presented, which can solve uncertainty and complexity problems of emergency logistics system evaluation. The model establishes...
