in recent years stock exchange has become one of the most attractive and growing businesses in respect of investment and profitability. but applying a scientific approach in this field is really troublesome because of variety and complexity of decision making factors in the field. this paper tries to deliver a new solution for portfolio selection based on multi criteria decision making literatu...

OBJECTIVE To develop and validate a new instrument that assesses women's autonomy and role in decision making during maternity care. DESIGN Through a community-based participatory research process, service users designed, content validated, and administered a cross-sectional quantitative survey, including 31 items on the experience of decision-making. SETTING AND PARTICIPANTS Pregnancy expe...

In wireless network applications, such as routing decision, selection, etc., the Multi-Attribute Decision Making (MADM) is widely used. The MADM approach can address multi-objective decision making issues effectively. However, when parameters vary greatly, traditional algorithm not effective anymore. To solve this problem, in paper, we propose pairwise-based algorithm. PMADM, only two nodes' ut...

The aim of this study was to provide an analytical tool to evaluate and select the best supplier(s)/vendor(s) in fuzzy environment for Television (TV) manufacturing organization. A hierarchy through which decision makers can bring about a comparison among the suppliers was worked out and software for the same was developed. The methodology for selection was based upon multiple criteria decision...

introduction tourism is a process which has been existed with all its special forms from the ancient times so that the mental, cultural, social and economic demands of the human beings can be met. one of the growing branches of this industry is named as ecotourism. nowadays, tourism has become one of the main levers of economic and social development in many regions of the world. tourism in the...

Hesitant fuzzy set (HFS), which allows the membership degree of an element to a set represented by several possible values, is considered as a powerful tool to express uncertain information in the process of multi-attribute decision making (MADM) problems. In this paper, we develop a novel approach based on TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) and the maximizi...

This paper reports the application of an evidential reasoning approach to design selection of retro-fit options for complex engineering products. The particular selection problem investigated in this paper is initially modelled by means of techno-economic analysis and may be viewed as a multiple attribute decision making (MADM) problem with a hierarchical structure of attributes which may be me...

Supplier selection is a multiple-attribute decision-making (MADM) problem. Since the decision makers (DMs) such as preferences on alternatives or on the attributes of suppliers are often uncertain, supplier selection becomes more difficult. Grey theory is one of the methods used to study uncertainty, being superior in the mathematical analysis of systems with uncertain information. In this pape...

Interval type-2 fuzzy set (IT2FS) offers interesting avenue to handle high order information and uncertainty in decision support system (DSS) when dealing with both extrinsic and intrinsic aspects of uncertainty. Recently, multiple attribute decision making (MADM) problems with interval type-2 fuzzy information have received increasing attentions both from researchers and practitioners. As a re...

In this paper, the authors propose an interval linguistic distribution model for multiple attribute decision making (MADM) problems with incomplete linguistic information, in which they use intervals as evaluators’ confidence levels indicating their belief degrees that a linguistic term fits an evaluation. By introducing the extent of ignoring information into this model, it can deal with incom...
