background and objectives: efficient hospital management requires appropriate cost and price strategies. informed decision on costs and prices of healthcare services needs estimation of costs of unit services using microeconomic techniques. there is lack of knowledge and skills for such costing methods in the healthcare sector of developing countries such as iran. this study aims at detail desc...

using the mathematic techniques such as fuzzy approach has useful outcomes for production planning in different sources. in this paper lgp1 was used to model the objectives such as: avoidance of shortage or surplus of demand, access to maximum of income, using the normal capacity of production and organizing the inventory of warehouse, within the framework of goal constraints like balancing be...

in this paper, we deal to obtain some new complexity results for solving semidefinite optimization (sdo) problem by interior-point methods (ipms). we define a new proximity function for the sdo by a new kernel function. furthermore we formulate an algorithm for a primal dual interior-point method (ipm) for the sdo by using the proximity function and give its complexity analysis, and then we sho...

in a region, optimal allocation of lands to various agricultural products is one of the most important issue associated with optimal use of agricultural resources. meta-goal programming is one of the multiple criteria decision models. this programming provides more flexible decisions for decision makers than other goal programming. in the current study, optimal cropping pattern was determined u...

multiple objective programming (mop) problems have become famous among many researchers due to more practical and realistic implementations. there have been a lot of methods proposed especially during the past four decades. in this paper, we develop a new algorithm based on a new approach to solve mop problems by starting from a utopian point (which is usually infeasible) and moving towards the...

in this paper, the portfolio selection problem is considered, where fuzziness and randomness appear simultaneously in optimization process. since return and dividend play an important role in such problems, a new model is developed in a mixed environment by incorporating fuzzy random variable as multi-objective nonlinear model. then a novel interactive approach is proposed to determine the pref...

background and objectives: quality services delivery in the health settings is contingent on hospital administrative staff organizational commitment. inspired by previous research indicating the prominent role of psychological empowerment in organizational commitment, this study aimed to explore the relationship between the two variables in hospital administrative staff. methods: a random sampl...

an interactive heuristic approach can offer a practical solution to the problem of linear integer programming (lip) by combining an optimization technique with the decision maker’s (dm) judgment and technical supervision. this is made possible using the concept of bicriterion linear programming (blp) problem in an integer environment. this model proposes two bicriterion linear programs for iden...

background and objectives: the reliability of hospital assessment results depends on the appropriateness of the indicators used. in this study, we systematically review the literature to identify the major indicators of hospital performance evaluation, as employed in performance assessment literature.methods: literature databases including pubmed, scopus, science direct, google scholar, doja, a...

background and objectives: hospital bed utilization is influenced by various factors, which may be categorized into patient-related, physician-related, and administration-related issues. it could be argued that the causes of inappropriate hospital bed utilization would be perceived differently by the clinicians and the patients. given the unique role of clinical practitioners in quality of care...
