tourism plays a very important role in the communities’ economic system development and therefore different countries compete to attract the international tourists, so marketing and specifically the issue of selecting target market are important. this study aims to identify the most important factors affecting iran's tourism industry target markets and prioritize these target markets. in t...

Analytic hierarchy process (AHP) is a utility theory based decision-making technique, which works on a premise that the decision-making of complex problems can be handled by structuring them into simple and comprehensible hierarchical structures. However, AHP involves human subjective evaluation, which introduces vagueness that necessitates the use of decision-making under uncertainty. The vagu...

Reservoir-induced seismicity is a very important issue in the study of geological analysis and ecoenvironmental impact assessment in hydraulic and hydropower engineering. On the other hand, reservoir-induced seismicity is a necessary consideration in the feasibility study of hydropower project. Due to the complexity in the process of reservoir-induced earthquake and the uncertainty of the influ...

Vehicle routing problem (VRP) is a combinatorial optimization and integer programming problem seeking to service a number of customers with a fleet of vehicles. Customer characteristics are neglected in traditional VRPs in the past due to the heterogeneity and ambiguousness. This study presents a vehicle route optimization model in consideration of customer characteristics with three major comp...

abstract: background: depending on the importance of a good performance appraisal system to achieve organizational strategies, balanced scorecard technique provides a comprehensive foundation for interpreting and translating organization’s vision and strategy in a set of performance measures by regarding an overall view of organization in four perspectives included customer, internal processes,...

This paper presents a fuzzy goal programming (FGP) procedure for solving multilevel programming problems (MLPPs) having chance constraints in large hierarchical decision organizations. In the proposed approach, first the chance constraints of a problem are converted into their respective deterministic equivalent in the decision making context. Then, the objective functions of decision makers (D...

The quality of water available to people has deteriorated because the vast increase in global industries. overall reduced due high use fertilizers farms and chemicals sectors such as mining construction. a direct impact on health humans hence it is necessary evaluate drinking water. dependent various substances like pH, ammonia, iron, arsenic etc. present If these parameters are an appropriate ...

In this thesis, an intelligent fuzzy logic system using genetic algorithms for the prediction and modelling of interest rates is developed. The proposed system uses a Hierarchical Fuzzy Logic system in which a genetic algorithm is used as a training method for learning the fuzzy rules knowledge bases. A fuzzy logic system is developed to model and predict three month quarterly interest rate flu...
