The implementation of Weighted Page Content Rank algorithm has been carried out and the result shows that it takes too much time to process the Web Pages. As the number of Web Pages increases, there is also increase in the processing time. So, in this paper, the Fuzzy Logic is implemented on WPCR algorithm to decrease the processing time of Web pages.

In this paper, we present logic-based aggregation models used for ranking student applicants and we compare them with a number of existing aggregation methods, each more complex than the previous one. The proposed models aim to include dependencies in the data using Logical aggregation (LA).

In this paper, a multi-objective economic order quantity model with shortages and demand dependent unit cost under storage space constraint is formulated. In real life situation, the objective and constraint goals and cost parameters are not precisely defined. These are defined in fuzzy environment. The cost parameters are represented here as triangular shaped fuzzy numbers with different types of left and right branch membership functions.

In this paper, a new fuzzy multi-criteria mathematical model for the selection of the best among a finite number of ordering policy of raw material in a supply chain is developed. The problem treated is a part of the purchasing plan of a company in an uncertain environment and it is very common in business practice. Optimization criteria selected describe the performance measures of ordering policies and generally their relative importance is different. It is assumed that the values of the optimization criteria are vague and imprecise.

This paper proposes a revised ranking approach to overcome the shortcomings of Liou and Wang’s ranking approach. The proposed ranking approach presents the novel left, right, and total integral values of the fuzzy numbers. The median value ranking approach is further applied to differentiate fuzzy numbers that have the compensation of areas.

This paper proposes an extension of fuzzy multi-criteria decision making (MCDM) approach for selecting solar PV energy technologies. In the proposed approach, several PV technologies are used as the alternatives. The ratings of alternatives - PV technologies under various criteria and the weights of criteria are assessed in linguistic terms represented by fuzzy numbers.

This paper presents the solution to problems of fuzzy ranking Vietnamese documents using approach of Hedge Algebra based on envaluating an accordance of found documents by heuristic criteria. These criteria firstly are evaluated by degree of importance (weight) and then are combined following some aggregation operator to define final evaluation unique number, that will be used for sorting the documents. The experimental results are presented to show the effectiveness of the proposed solution.

Abstract Amulti-attribute group decisionmakingmethod composed of intuitionistic fuzzy set and TOPSIS will be introduced into project material bidding procurement. First, the opinions of experts about bidders and indicators’ attributes are expressed by linguistic terms, and then turned into intuitionistic fuzzy numbers, which can be used to obtain the weights of the indicators’ attributes and experts. Based on the opinions of decision makers and IFWA operators, an aggregated intuitionistic fuzzy decision matrix is formulated. In the end, the bidders are ranked by TOPSIS method....
