abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...

In today’s competitive markets, customer satisfaction is the main goal for all managers, and at a hospital what the most adapted bed allocation policy is, a research subject is for many researchers to gain more customer satisfaction. Researchers have presented a variety of methods on allocating beds to the patients, based on their type of customers and problems. In this paper, goal programming ...

Background and Aim:  Hospital as an economic entity, should utilize economic analysis for the optimal use of resources and production facilities. The aim of this study was to estimate the production function of Ahvaz University of Medical Sciences during the period 2006-2014. Materials and Methods: This study was a descriptive cross-sectional analysis. The Data were collected during a period o...

Background and Objectives:Among health sector resources, hospital beds are the primary unit of calculation for the capacity of the health service and vital capacity in patient care. Lack of appropriate distribution in different parts of the country leads to transfer of patients and irreparable problems. The aim of this study was to provide accurate information on the number and distribution of ...

abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...

Background: Deciding on the number of hospital beds is one of the most serious challenges managers face. More hospital beds result in higher running cost although less hospital beds might cause disorder in patients flow.  Minimizing total cost besides maximizing the patients flow in a hospital network, considering the practical limitations is the main objective of this survey. Materials & Me...

Introduction: The number of physicians and hospital beds is one of the major factors affecting on health costs in the supply side, which is posited in the health economics issues called inductive demand hypothesis. According to this hypothesis, health care demand may be due to asymmetric information in health market, is influenced by the behavior of health suppliers. Therefore, the purpose of t...
