Assessing E-commerce web sites quality is essential not only to have recommendations for improvement but also to make comparisons with competitors. In this paper, the aim is to know the best criteria for the evaluation and obtain a weight for them using fuzzy Analytic Network Process (fuzzy ANP). The subjective judgments of the decision maker are expressed by fuzzy numbers. The decision making problem...
Recently, the study of the skyline and its variants has received considerable attention in various applications that require decision making and personalized services. The skyline is essentially a set of the most interesting (not dominated) tuples in the queried database. They are based on the concept of Pareto dominance. The skyline computation may lead to two scenarios: either (i) a huge number...
An approach to multi attribute group decision making with intuitionistic fuzzy setting has been described. In the present article, the application of proposed ranking method based on value and ambiguity has been studied. A multi attribute group decision making problem has been studied with an illustrative numerical example.
In this work we consider an application of the network operator method for the intelligent control system synthesis. This system should guarantee object to meet several goals. If we weaken precision conditions, control system becomes optimal with respect to the general criterion. To solve the problem of synthesis the network operator method was used. This method allows searching for two multidimensional...
Techniques for ranking simple fuzzy numbers are abundant in nature. However, we lack effective methods for ranking intuitionistic fuzzy numbers(IFN). The aim of this paper is to introduce a new ranking procedure for trapezoidal intuitionistic fuzzy number(TRIFN). To serve the purpose, the value and ambiguity index of TRIFNs have been defined. In order to rank TRIFNs, we have defined a ranking function...
This paper proposes a method for comparison of coalition influence in the framework of social welfare function which is a model of group decision. The proposed method compares a pair of coalitions from the point of view how different the opinion which the coalition has with respect to the collective decision is. Some examples how the proposed method work are provided in this paper. It is verified...
Based on six types of relations such as deviation, intersection and inclusion among interval numbers, this paper presents an interval negotiation decision-making model on QoS information between service provider and service requester, including a trade-off and concession algorithm to determine the interval negotiation boundary. Additionally, the negotiation protocol and algorithm description are put...
In order to measure and evaluate the uncertain factors impacting on the due date of product, the impact factors of the completion date of product on shop floor is intensive investigated firstly. The data of uncertain factors which affected the completion date of products are sorted out, the decision system was made of impact factors that correlative with the completion date of product, and was analyzed...
In this paper, through by using the AHP (Analytic Hierarchy Process) method's basic theory analysis in online-teaching platform, analyzing ability of students' self-learning, and establishing the evaluation index system, according to expert criteria derived the value of influence factors. With it calculated every level index's weight by using the square root method, and implements the weight by given...
Recent developments in cutting tool materials of CNC maching have brought many exciting changes in the field of metal cutting . Machine operators can benefit from wider selection of insert grade in cutting process. On the other hand, selecting the optium insert grade from its increasing number of existing alternatives in workshop is multiple-criteria decision making (MCDM) problem in the presence...
The software quality evaluation problem is becoming increasingly important for software providers and their users. Existing most methods suitable for software quality evaluation are provided based on multiple-attribute decision-making (MADM) model. In this paper, an integration method of a fuzzy matter element (FME) and analytic hierarchy process (AHP) is used to consider quantitative and qualitative...
Human-machine environment evaluation of digital workshop involves physical, chemical, psychological, social environment for the workshop and many other factors. Attribution reductions of rough set theory reduces some redundant targets which are less important to human environmental assessment, thus to obtain the important index and to improve the ergonomic effect of the environmental layout of the...
To promote the information technology development of the textile enterprise, achieve production information integration and data share for all the workshops in the local area network(LAN), in this paper, first, we analyze the actual system requirements, study the weaknesses of the existing computer monitoring system, introduce the system design project, propose the network model based on C/S mode,...
This paper extends the framework of power indices and proposes a notion of coalition power indices to evaluate influence of each coalition in simple games. A coalition power index is defined as a map that assigns a real number to each pair of a simple game and a coalition in the game. The blockability index is then defined as an example of coalition power indices based on the blockability relations...
The optimization and selection procedure of logistics center facilities layout projects has an important status in the logistics system layout and planning. Aiming at the deficiencies existing in the logistics center facilities layout projects optimization and selection, a new optimization frame was developed. Based on the analysis to the recent relevant studies, the evaluation index system for logistics...
We focus on an opportunistic communication system consisting of multiple independent channels with time-varying states. With limited sensing, a user can only sense and access a subset of channels and accrue rewards determined by the state of the sensed channels. We formulate the problem of optimal sequential channel probing as a restless multi-armed bandit process, for which a powerful index policy-Whittle's...
