Uncertainty and variability are always to some extent present in numerical simulations. Especially in the model definition phase, lack of information, scatter in material properties or environmental conditions imply that a designer should incorporate the possible effects of this
Fuzzy Optimal Solution to Fuzzy Transportation Problem: A New Approach
In this paper we propose a new algorithm for the initial fuzzy feasible solution to a fully fuzzy transportation problem. Then by using fuzzy version of modified distribution method, we obtain the fuzzy optimal solution for the fully fuzzy transportation problem without convertin
Importance-Assessing Method with Fuzzy Number-Valued Fuzzy Measures and Discussions on TFNs And TrFNs
The weight is one of the most useful tools to measure the attribute importance when individuals make a decision or evaluate the alternatives. Among the methods which measure the weight, fuzzy measures is are subjective scales for the degrees of fuzziness and widely used to determ
On replacement models via a fuzzy set theoretic framework
| Uncertainty is present in virtually all replacement decisions due to unknown future events, such as revenue streams, maintenance costs, and in°ation. Fuzzy sets provide a mathematical framework for explicitly incorporating imprecision into the decision making model, especially
A New Fuzzy Positive and Negative Ideal Solution for Fuzzy TOPSIS
This paper presents a fuzzy multiple criteria decision making (FMCDM) problem with the Technique for Order Performance by Similarity to Ideal Solution (TOPSIS) based on the new concept of positive and negative ideal solution. Whereas decision making is a process which accuracy of
Multi-attribute and Multi-criteria Decision Making Model for technology selection using fuzzy logic
The problem of identification and elimination of useful technology is a multi-attribute, multi-valued problem which involves both tangible and intangible factors. To select the best useful technology that achieves most of the company requirements, it is essential to use an approp
Industrial Supply Chain Performance Benchmarking using Fuzzy Grey Relation Method
Present work aims to develop an efficient decision support system (DSS) to facilitate supply chain performance appraisement, benchmarking and related decision-making. Supply chain performance extent can be attributed as a function of multiple criteria/attributes. Most of the crit
Robot selection by a multiple criteria complex proportional assessment method under an interval-valued fuzzy environment
Recent research is recognizing that multiple criteria analysis should take account of the concepts of uncertainty and risk. In some cases, precise determination of the exact value of alternatives and weights of criteria is difficult. Consequently, to deal with these potential pro
The equilibrium quantity and production strategy in a fuzzy random decision environment: Game approach and case study in glass substrates industries
This paper develops a two-stage Cournot production game that integrates strategic and operational planning under the fuzzy random environment, which to our best knowledge has not appeared in the literature. At the strategic level, two competing decision-makers determine the upper
Fuzzy Multi-Criteria Decision-Making for Evaluating the performance of mutual funds
This paper describes a fuzzy hierarchical analytic approach to determine the weighting of subjective judgments. In addition, it presents a nonadditive fuzzy integral technique to evaluate a mutual fund case as a fuzzy multi-criteria decision-making (FMCDM) problem. When the inves
