Financial problems have been the subject of much research. A widely used approach in recent work on these problems is the use of fuzzy set theory, where fuzzy terms are used to model the uncertain environments. The purpose of this work is to combine the fuzzy analytic hierarchy process (AHP) with the portfolio selection problem. More specifically, the decision-making problem is to decide which ...

selecting an appropriate manufacturing machine is a very important and complex problem for firms, which usually have to deal with both qualitative and quantitative criteria. taking into account the differences among machines in terms of cost, speed, quality and after sale services, type and number of machines are important parameters to consider. therefore, the goal of this paper is to propose ...

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 (AHP) has been identified as the tool that would help in Multi Criteria Decision Making. Researchers ...

Decision-making models often deal with problems that involve multiple criteria analysis in order to assess alternatives in various decision-making settings. On the basis of a systematic process, the Analytic Hierarchy Process (AHP) has recently been recognized as a proven decision-making tool in a wide variety of fields. However, new methods to cope with evolving or scaled problems are emerging...

abstract- according to article 44 of the i.r. of iran constitution, the iranian economy consists of three sectors; the state, the cooperative, and the private sectors. the aim of this study was to present a hierarchy of criteria for selecting the best economic sector for agricultural development. analytic hierarchy process (ahp) was used to calculate the relative importance of either criteria o...

The supplier selection exercise is a critical factor towards the success of a company. This paper compares four different methods to support decision makers in selecting the most appropriate supplier. When using Fuzzy logic, the importance of each criterion gets influenced by the level of decomposition in the hierarchical model. Fuzzy logic does not have the capability to measure the level of c...

Decision making is an important issue in business and project management that assists finding the optimal alternative from a number of feasible alternatives. Decision making requires adequate consideration of uncertainty in projects. In this paper, in order to address uncertainty of project environments, interval type-2 fuzzy sets (IT2FSs) are used. In other words, the rating of each alternativ...

multi-criteria evaluation methods (mcem) have been widely used in the scientific arena as well as in urban and regional planning. the analytic network process (anp) is one the mcem that includes relevant tangible as well as intangible criteria and sub-criteria. it allows for a more complex relationship among the decision levels and attributes, as it does not require a strict hierarchical struct...
