Relations on neutrosophic multi sets with properties
In this paper, we first give the cartesian product of two neutrosophic multi
sets(NMS). Then, we define relations on neutrosophic multi sets to extend the
intuitionistic fuzzy multi relations to neutrosophic multi relations. The
relations allows to compose two neutrosophic sets. Also, various properties
like reflexivity, symmetry and transitivity are studied
Solution of the Decision Making Problems using Fuzzy Soft Relations
The Fuzzy Modeling has been applied in a wide variety of fields such as
Engineering and Management Sciences and Social Sciences to solve a number
Decision Making Problems which involve impreciseness, uncertainty and vagueness
in data. In particular, applications of this Modeling technique in Decision
Making Problems have remarkable significance. These problems have been tackled
using various theories such as Probability theory, Fuzzy Set Theory, Rough Set
Theory, Vague Set Theory, Approximate Reasoning Theory etc. which lack in
parameterization of the tools due to which they could not be applied
successfully to such problems. The concept of Soft Set has a promising
potential for giving an optimal solution for these problems. With the
motivation of this new concept, in this paper we define the concepts of Soft
Relation and Fuzzy Soft Relation and then apply them to solve a number of
Decision Making Problems. The advantages of Fuzzy Soft Relation compared to
other paradigms are discussed. To the best of our knowledge this is the first
work on the application of Fuzzy Soft Relation to the Decision Making Problems.Comment: 29 Pages Journal Paper, International Journal of Information

The use of soft matrices on soft multisets in an optimal decision process
In this paper, we introduce a concept of a soft matrix on a soft multiset,
and investigate how to use soft matrices to solve decision making problems. An
algorithm for a multiple choose selection problem is also provided. Finally, we
demonstrate an illustrative example to show the decision making steps.Comment: 16 page

Land cover classification using fuzzy rules and aggregation of contextual information through evidence theory
Land cover classification using multispectral satellite image is a very
challenging task with numerous practical applications. We propose a multi-stage
classifier that involves fuzzy rule extraction from the training data and then
generation of a possibilistic label vector for each pixel using the fuzzy rule
base. To exploit the spatial correlation of land cover types we propose four
different information aggregation methods which use the possibilistic class
label of a pixel and those of its eight spatial neighbors for making the final
classification decision. Three of the aggregation methods use Dempster-Shafer
theory of evidence while the remaining one is modeled after the fuzzy k-NN
rule. The proposed methods are tested with two benchmark seven channel
satellite images and the results are found to be quite satisfactory. They are
also compared with a Markov random field (MRF) model-based contextual
classification method and found to perform consistently better.Comment: 14 pages, 2 figure
A Method with Feedback for Aggregation of Group Incomplete Pair-Wise Comparisons
A method for aggregation of expert estimates in small groups is proposed. The
method is based on combinatorial approach to decomposition of pair-wise
comparison matrices and to processing of expert data. It also uses the basic
principles of Analytic Hierarchy/Network Process approaches, such as building
of criteria hierarchy to decompose and describe the problem, and evaluation of
objects by means of pair-wise comparisons. It allows to derive priorities based
on group incomplete pair-wise comparisons and to organize feedback with experts
in order to achieve sufficient agreement of their estimates. Double entropy
inter-rater index is suggested for usage as agreement measure. Every expert is
given an opportunity to use the scale, in which the degree of detail (number of
points/grades) most adequately reflects this expert's competence in the issue
under consideration, for every single pair comparison. The method takes all
conceptual levels of individual expert competence (subject domain, specific
problem, individual pair-wise comparison matrix, separate pair-wise comparison)
into consideration. The method is intended to be used in the process of
strategic planning in weakly-structured subject domains.Comment: 13 pages, 6 figure
Predicting Suicide Attacks: A Fuzzy Soft Set Approach
This paper models a decision support system to predict the occurance of
suicide attack in a given collection of cities. The system comprises two parts.
First part analyzes and identifies the factors which affect the prediction.
Admitting incomplete information and use of linguistic terms by experts, as two
characteristic features of this peculiar prediction problem we exploit the
Theory of Fuzzy Soft Sets. Hence the Part 2 of the model is an algorithm vz.
FSP which takes the assessment of factors given in Part 1 as its input and
produces a possibility profile of cities likely to receive the accident. The
algorithm is of O(2^n) complexity. It has been illustrated by an example solved
in detail. Simulation results for the algorithm have been presented which give
insight into the strengths and weaknesses of FSP. Three different decision
making measures have been simulated and compared in our discussion.Comment: Submitted manuscrip
A new and efficient intelligent collaboration scheme for fashion design
Technology-mediated collaboration process has been extensively studied for over a decade. Most applications with collaboration concepts reported in the literature focus on enhancing efficiency and effectiveness of the decision-making processes in objective and well-structured workflows. However, relatively few previous studies have investigated the applications of collaboration schemes to problems with subjective and unstructured nature. In this paper, we explore a new intelligent collaboration scheme for fashion design which, by nature, relies heavily on human judgment and creativity. Techniques such as multicriteria decision making, fuzzy logic, and artificial neural network (ANN) models are employed. Industrial data sets are used for the analysis. Our experimental results suggest that the proposed scheme exhibits significant improvement over the traditional method in terms of the time–cost effectiveness, and a company interview with design professionals has confirmed its effectiveness and significance
Necessary and Sufficient Conditions for Surrogate Functions of Pareto Frontiers and Their Synthesis Using Gaussian Processes
This paper introduces the necessary and sufficient conditions that surrogate
functions must satisfy to properly define frontiers of non-dominated solutions
in multi-objective optimization problems. These new conditions work directly on
the objective space, thus being agnostic about how the solutions are evaluated.
Therefore, real objectives or user-designed objectives' surrogates are allowed,
opening the possibility of linking independent objective surrogates. To
illustrate the practical consequences of adopting the proposed conditions, we
use Gaussian processes as surrogates endowed with monotonicity soft constraints
and with an adjustable degree of flexibility, and compare them to regular
Gaussian processes and to a frontier surrogate method in the literature that is
the closest to the method proposed in this paper. Results show that the
necessary and sufficient conditions proposed here are finely managed by the
constrained Gaussian process, guiding to high-quality surrogates capable of
suitably synthesizing an approximation to the Pareto frontier in challenging
instances of multi-objective optimization, while an existing approach that does
not take the theory proposed in consideration defines surrogates which greatly
violate the conditions to describe a valid frontier
Multi criteria decision making approach for selecting effort estimation model
Effort Estimation has always been a challenging task for the Project
managers. Many researchers have tried to help them by creating different types
of models. This has been already proved that none is successful for all types
of projects and every type of environment. Analytic Hierarchy Process has been
identified as the tool that would help in Multi Criteria Decision Making.
Researchers have identified that Analytic Hierarchy Process can be used for the
comparison of effort estimation of different models and techniques. But the
problem with traditional Analytic Hierarchy Process is its inability to deal
with the imprecision and subjectivity in the pairwise comparison process. The
motive of this paper is to propose Fuzzy Analytic Hierarchy Process, which can
be used to rectify the subjectivity and imprecision of Analytic Hierarchy
Process and can be used for selecting the type of Model best suited for
estimating the effort for a given problem type or environment. Instead of
single crisp value, Fuzzy Analytic Hierarchy Process uses a range of values to
incorporate decision maker uncertainty. From this range, decision maker can
select the value that reflects his confidence and also he can specify his
attitude like optimistic, pessimistic or moderate. In this work, the comparison
of Analytic Hierarchy Process and Fuzzy Analytic Hierarchy Process is concluded
using a case study of selection of effort estimation model
