Hierarchical control structures are composed of local decision making units and a supremal unit (coordinator). The present work deals with a well known hierarchical algorithm based on linearized augmented Lagrangian. An extension of the algorithm for the case of global constraints is given. The algorithm has been applied to several problems and the execution time of the hierarchical algorithm h...

As the result of the development of Fuzzy Multiple Criteria Decision Making (FMCDM) with the help of fuzzy set theory a number of innovations have been made possible. The new approach of FMCDM – Fuzzy Hierarchical Modeling is introduced. It is shown in the article, how to use the fuzzy hierarchical model with other methods of FMCDM. Advantages of the method are described also. We propose a nove...

this is a cross sectional study with aim of assessment and comparison between parents and female adolescents ' attitudes about the role of peers in decision making of adolescent in tehran. in this study 160 mother, 160 father and 160 female adolescents participated. with random selection 160 female adolescent with 14-19 years old from north, south , east and west of tehran were selected an...

introduction: customer satisfaction has been suggested as one of the interesting and challenging issues of management in the new millennium. in addition, oral and dental health and the quality of the services the health centers delivered to the patients directly affect the customer satisfaction. therefore, the present study aimed to identify, investigate, and rank the factors affecting the cust...

results all the frames that were examined leaded to significant framing effects: when the asia disease problem was described in a positive frame, the participants preferred the conservative frame than the risky one, while if in a negative frame, the preference reversed (p < 0.01). if the drug effect was described as “of 100 patients taking this kind of medicine, 70 patients became better”, peop...

Background and Objectives: Prioritizing the services to be outsourced is a crucial challenge toward efficient outsourcing of health services. In spite of fruitful efforts in improving the outsourcing process, there still remains room and need for developing more systematic approaches. The present paper introduces a novel multi-criteria decision making model based on the fuzzy a...

Multistep decision making pervades daily life, but its underlying mechanisms remain obscure. We distinguish four prominent models of multistep decision making, namely serial stage, hierarchical evidence integration, hierarchical leaky competing accumulation (HLCA), and probabilistic evidence integration (PEI). To empirically disentangle these models, we design a two-step reward-based decision p...

Quantum decision models have been recently proposed to account for findings that have resisted explanation by traditional decision theories. This paper compares quantum versus Markov models of decision making for explaining a puzzling empirical finding from human decision making called dynamic inconsistency – that is the failure of decision makers to carry out their planned decisions. A large d...
