The aim of the work is to review and analyze the ideas and possibilities of modeling social welfare optimization based on the essential premises of neoclassical schools on consumer choice optimization. The work explains current and often controversial conceptions of basic postulates of economic welfare. It deals with the problems of defining the functions of social welfare, conceptions about the principles...
The aim of the work is the presentation, critical analysis and the evaluation of contemporary ideas and dilemmas on the basic hypotheses and axioms for consumer behavior modeling. Considerations in the work include the ideas on consumer sovereignty, supposition of consistency and persistency of consumer choice, choice rationality in the conditions of uncertainty and risks, the problems of rational...
The advances in computer science and informatics provide the basis for creating modern health diagnostics algorithms and instruments. One of the evaluation methods of reference ECG signals is based on the Minnesota code. This is a rule based system, which provides a value based criteria for specific ECG parameters. There are several studies which have tried to determine the effectiveness of the computer...
To measure efficiency of DMUs (Decision Making Units), DEA (Data Envelopment Analysis) clarifies relations between input and output elements respectively. Although selection of these data is entrusted to analyst, criteria of selection are not universal. Therefore, reasonability of data selection is sometimes controversial. Then the purpose of this study is to obtain input and output elements based...
Index structure system of urban rail transit is analyzed and optimized by applying information entropy. In this paper, a security evaluating C2R model on analyzing urban rail transit is set up based on DEA. Finally, a case study about Guangzhou Metro Line 1 is carried out, and annual relative validity of subway operation safety is evaluated by using the Matlab software program. According to the results...
Electronic commerce as a new model of business operation plays an important role in promoting global economic development. Electronic commerce is changing many aspects of logistics, and promoting the development of logistics greatly. At the same time, if there is no modern logistics, business activities will become difficult. For enterprises, the right logistics model chosen is necessary. Therefore,...
At container terminals, containers are transported from the marshalling yard to the quay and vice versa by Container Trucks (CTs). This study discusses how to dispatch CTs by utilizing information about pickup and delivery locations and time in future delivery tasks based on dynamic dispatching strategy in which multiple tasks are matched with multiple CTs. In this paper, Multi-agent system (MAS)...
For features of planning and design's evaluation, and on basis of the principles of establishing evaluation index system, this paper established the comprehensive evaluation index system of residential planning and design program; In the use of analytical hierarchy process to determine weights of evaluation indexes, and based on the character of fuzzy comprehensive evaluation method that using dimensionless...
Geometric precisions are incorporated into a relational database from the perspective of geometric parameter precision design of the new generation of GPS and using the database technology. The processes can be simulated of their reasoning and decision-making in solving mechanical problems combining the theoretical knowledge, factual data and heuristic knowledge from the experience of specialists...
The traditional Chinese medicine industry is a field that has unique advantage and national characteristics in the industrial field of our country. The evaluation of the enterprise core competence plays an important role in the rapid development of the traditional Chinese medicine industry. In this paper, a comprehensive evaluation model of the Chinese medicine enterprise core competence is proposed...
In this paper, we extend the traditional grey situation decision to the case of decision information serving as interval grey number, and provide multi-objective weight optimization model of multi-objective grey situation decision. Taking the deviation in different objectives among the effect measure of each situation, positive and negative ideal into consideration first, the optimization model is...
This thesis analyzes the characteristics of cold chain logistics and establishes the index system of the location of logistics distribution center. The gray comprehensive evaluation applies gray correlation analysis as well as the AHP and studies the location of cold logistics distribution center with the organic integration of the two methods. Finally it is proved with the combination of the case.
The newest methods of scientometrics and the visibility technology are used to to draw up scientific knowledge mapping of co-word network of the contemporary international manufacturing and to lay out that there are three main knowledge clusters of research fronts in international manufacturing, and the paper opens out their subject adscription and correlation, and more the paper expounds three main...
In this paper, the GIS application in the emergency command and status of JDL information fusion model and the characteristics of the five stages are introduced. With combination of GIS and the JDL, studied the characteristics of the campus emergency command, combined with the actual situation and needs, analyzed and re-definition of the five stages of information fusion, information fusion model...
To solve the problem of supplier selection, the author considered the multiple attributes and established multi-attribute decision making model decided by many people. Firstly, the supplier's comprehensive scheduling is given by using TOPSIS method ,then determining group scheduling which is the most consistent to each member's scheduling by using Cook - Seiford function included in SCF (social choice...
This paper analyzed the principles of TOPSIS, used the fuzzy set to pretreat the uncertainty factors in evaluation work. Then obtain the relative closeness according to the distance between each schemes and positive ideal solutions as well as negative ideal solutions. After that, we made comprehensive evaluation. At the end of this paper, a practical example is given to illustrate the effectiveness...
Suppliers plays a vital role in terms of its ability to provide reliable quality services, which directly determines the credibility of corporate success. In order to solve the problems related to selection of suppliers, we, in this paper, introduce the concept of module design while combining with mixed update mechanism, and then propose a choice model for best trustworthy supplier called BTSM. First...
An issue of considerable importance, involves the problem of how to simultaneously allocate a fixed input resources and set targets among a set of competing entities in an equitable way. Based on data envelopment analysis (DEA), the current paper proposes a new method for simultaneously allocating fixed input resources and setting targets to all decision making units (DMUs), in such a way that all...
In this paper, the multi-period fuzzy multi-attribute decision making is discussed, where the attribute values are considered as triangular fuzzy variables. A new approach to determine the weights of all periods is proposed. The weighted distance operator and the dynamic weighted distance operator are proposed. A distance method for multi-period fuzzy multi-attribute decision making is presented....
Strategic choice for enterprises is a complex multi-level question of decision-making, and the traditional qualitative methods can't meet the needs of the decision. Considering the various qualitative and quantitative indicators, this paper uses the fuzzy synthetic evaluation methods featuring in entropy of information based on SWOT to establish the strategic choice model of the decision-making, and...
