In general fuzzy linear regression, the coefficients of the fuzzy regression model are symmetric triangular fuzzy numbers, while we try to replace them by more general ones, which are asymmetric trapezoidal fuzzy numbers. Possibility of equality between two asymmetric trapezoidal
On the Implementation of Fuzzy Arithmetical Operations for Engineering Problems
Fuzzy arithmetic is a successful tool to solve engineering problems with uncertain parameters. The generalized mathematical operations for fuzzy numbers can theoretically be defined making use of Zadeh’s extension principle. Practical real-world applications of fuzzy arithmetic,
Fuzzy Economic Decision-models for Information Security Investment
Present paper derives fuzzy economic models to evaluate the economic feasibility of information security investment. The Net Present Value (NPV), and discounted Return on Investment (dRoI) models are proposed for the execution of costbenefit analysis. Since fuzzy results are in t
Extensions of the multicriteria analysis with pairwise comparison under a fuzzy environment
Multicriteria decision-making (MCDM) problems often involve a complex decision process in which multiple requirements and fuzzy conditions have to be taken into consideration simultaneously. The existing approaches for solving this problem in a fuzzy environment are complex. Comb
a new multi-criteria decision making based on fuzzy- topsis theory
abstract— in this paper, a new extended method of multi criteria decision making based on fuzzy-topsis theory is introduced. fuzzy mcdm algorithm for determining the best choice among all possible choices when the data are fuzzy is also presented. using a new index leads to proce
Evaluating emergency response capacity by fuzzy AHP and 2-tuple fuzzy linguistic approach
Emergency management (EM) is a very important issue with various kinds of emergency events frequently taking place. One of the most important components of EM is to evaluate the emergency response capacity (ERC) of emergency department or emergency alternative. Because of time pr
A Fuzzy Inventory System with Deteriorating Items under Supplier Credits Linked to Ordering Quantity
The inventory problem associated with trade credit is a popular topic in which interest income and interest payments are important issues. Most studies related to trade credit assume that the interest rate is both fixed and predetermined. However, in the real market, many factors
Fuzzy set theory based methodology for the analysis of measurement uncertainties in river discharge and stage
The discharge and stage measurements in a river system are characterized by a number of sources of uncertainty, which affects the accuracy of a rating curve established from measurements. This paper presents a fuzzy set theory based methodology for consideration of different sour
Fuzzy AHP Method for Selection of a Suitable Seismic Retrofitting Alternative in Low-Rise Buildings
Decision making for selecting an appropriate alternative among nominated alternatives is still a problem among retrofit designers. It is clear that selected alternative should comply the current codes in terms of structural criteria, but the other criteria may not be considered.
Supplier selection and order allocation based on fuzzy SWOT analysis and fuzzy linear programming
Supplier selection is a multi criteria decision-making problem that comprises tangible and intangible factors. The majority of previous supplier selection techniques do not consider strategic perspective. Besides, uncertainty is one of the most important obstacles in supplier sel
