Abstract:Decision making is the process of finding the best option among the feasible alternatives. In classical multiple criteria decision making methods, the ratings and the weights of the criteria are known precisely. However, if decision makers are not able to involve uncertainty in the defining of linguistic variables based on fuzzy sets, the intuitionistic fuzzy set theory can do this job very well. In this paper, VIKOR method is extended in intuitionistic fuzzy environment, aiming at solving multiple-criteria decision making problems in which the weights of criteria and ratings of alternatives are taken as triangular intuitionistic fuzzy set. For application and verification, this study presents a logistic service provider selection …show more content…
Most of the complex real life problems are with conflicting multi-criteria. A lot of work has been done on these complex structured multi-criteria problems and many methods are proposed to deal with them. MCDM methods are an extensively applied tool for determining the best solution among several alternatives with multiple criteria or attributes. The procedures for determining the best solution to a MCDM problem include computing the utilities of alternatives and ranking these utilities. The alternative solution with the largest utility is considered to be the optimal solution. Due to the complex structure of the problem and conflicting nature of the criteria, a compromise solution for a problem can help the decision maker to reach a final decision. Recently Opricovic and Tzeng [15] has developed VIKOR method for multi-attribute optimization of complex systems. It determines the compromise ranking list, the compromise solution, and the weight stability intervals for preference stability of the compromise solution obtained with initial given weights. The method focuses on ranking and selecting from a set of alternatives in the presence of conflicting attributes. The VIKOR method provides a maximum group utility for the majority and a minimum of an individual regret for the opponent. It introduces the multi-attribute ranking indexes based on the particular measure of closeness to the ideal solution. …show more content…
As Fuzzy set theory (Zimmerman, 1983, 1987) [25, 26] came into existence, many extensions of fuzzy sets also have appeared over the time and traditional fuzzy decision making models have been extended to include these extended fuzzy type descriptions. One among these extensions of fuzzy sets is Intuitionistic Fuzzy Sets (IFSs) (Atanassov, 1986) [3] playing an important role in decision making and have gained popularity in recent years. In IFS theory sum of degree of membership and degree of non-membership do not simply equals one as in the conventional fuzzy sets. Such an extended definition helps more adequately to represent situations when decision maker obtain from expressing their assessments. By this way, IFSs provide a richer tool to grasp imprecision than the conventional fuzzy sets. This feature of IFSs has led to extend VIKOR in intuitionistic fuzzy (IF)-environment.
In order to achieve the above purposes, this paper’s organization structure is as follows. In the next section, we represent the IFS, HIFEs, IHFSs, the traditional VIKOR method. In section 3, we extend the traditional VIKOR method based on intuitionistic hesitant fuzzy set, and an approach is given. In Section 4, we give a numerical example to elaborate the effectiveness and feasibility of our
I have chosen the predictive modeling assignment as a project to prioritize the three critical constraints scope, time and money of the priority matrix. Here, the project champion is my professor with whom I have discussed regarding the negotiation of the constraints to complete the project successfully with the given budget and time specified. Firstly, consider the budget for the project .It will be rigid as our professor gave me a SAS JMP software to get installed in my system to complete the project. So, money will be the least priority.
The knowledge base consists of a collection of fuzzy if-then rules of the following form: $R^{l}$: if $x_1$ is $F_1^{l}$ and $x_2$ is $F_2^{l}$ and $ldots$ and $x_n$ is $F_n^{l}$, then is $G^{l},~l=1,2, cdots ,n$, where $x=[x_1,cdots,x_i]^{T}$ and $y$ are the FLS input and output, respectively. Fuzzy sets $F_i^{l}$ and $G^{l}$, associated with the fuzzy functions $mu_{{F_i}^{l}}(x_i)$ and $mu_{{G}^{l}}(y)$, respectively. $N$ is the rules inference number. \Through singleton function, center average defuzzification and product inference cite{shaocheng2000fuzzy}, the FLS can be expressed as: For any continuous function $f(x)$ defined on a compact set $Omegain R^n$, there exists a fuzzy system $y(x) = heta ^T
Technology related (Positive) and Science related (Negative). You take into account support factor also consisting of support = 50, support = 75 and support= 90. You also take training set of 6 documents in which you take 3 positive documents and 3 negative documents. Basing on the support factors you have calculated documents weights and also uniquely calculated document weights by PTM method which you discussed earlier. Doc/Sup 50
It is the statistic analysis in the cricket baseball and softball and it measures the performance of batters in baseball. and development of this statistics influenced on baseball, at this moment it can also find out the top hitters too. (Moy, 2006) Third formula is defensive efficiency rating: the ratio of team defensive outs recorded in defensive opponents= 1-((total number of hits-home runs allowed)/(all balls hit into play-home runs allowed))
Political scientists and historians have always been on the opposite sides on the subject of how a decision is made. Political Scientists claim that by knowing a few details into the major players prior preferences that all future actions can be predicted by using that Rational Actors Model. However, historians refute this theory arguing that without knowing the context or the environment of the player, one can never truly understand the decision making process. By using the events which led to the internment of Japanese Americans I hope to show that any event can fit the model in hindsight but at the time of the actual decision there could have been many options for Japanese Americans short of internment.

One of the most common action that businesses as well as individuals needs to face on a daily basis is a decision making process. Some of the choices can be difficult, other very simple , yet no matter on the situation these choices can have a large impact on our future life. As we are all aware, conflict can occur very fast and easily, so for the same reason it is important to learn how to effectively deal with these kind of problems. There are many different techniques which we can use while reducing the tension , yet the six step model process is known as the most effective.
Target corporation has many different location-related decisions to process in more than one aspect. The company must decide on the location of its retail stores, manufactures, and support help. Often the decision to outsource or participate in offshoring can be tempting to a company. Well the impact of outsourcing and offshoring must be examined to ensure that the decision is in the best interest of the company.
It is a systematic method that utilizes knowledge, measures, and environmental analysis to produce the most ideal solution. Each decision is analyzed based on its possible consequences with an emphasis on short and long-term solutions. These processes require ample amounts of information, time, and people. While quality solutions are produced, the willful choice model does not allow for flexibility regarding environmental changes such as technology and healthcare policy. Internal changes including turnover also negatively impact the rational decision process.
5.1: Identify ways of supporting an individual to make informed choices. In a health and social care there are many ways you can support individual 's that you may work with, to make some informed choices. As a career worker it is important that you are not judging while communicating, empowering and encouraging the individual to make informed choices, while respecting their choices as well as supporting them to challenge or question their decisions concerning that are made on their behalf to make sure that they are awake and have a full knowledge.

Behaviour is the way in which we act, speak and treat other people and our environment. Children and young people whose early social and emotional development is positive are more likely to make friends, settle well into school and understand how to behave appropriately in different situations. They have strong self- esteem and a sense of self- worth, but also have a feeling of empathy for others. They understand what the boundaries are, and why they are necessary. Behaviour has a significant impact on current and later success for children and young people, in terms of their social skill development, education and employment.
