Abstract
Background: Achieved results from this research shows that despite in health system in country efficiencies such as work force efficiency(doctors and nurses) is not incomputable and percentage of bed occupation and regulating shift work program prepare manually and with paper, this issue results in time consuming of managers and wasting costs and errors in carried out computations. Therefore with technology improvement and automation system there is possibility of making such automatic data is provided. Using of intelligent system consider essentially for preparing optimal program. Studying of Data showed that the present situation of planning and determination of efficiency in Iran Hospitals is not desirable. In this research, Markov methods and Petri net and genetic algorithm as modeling method and developments of model and intelligent optimization for solving problems, reducing costs and planning for work force was used successfully and there is the possibility to generalize it with changes and reforms in programming. In Achieved results of studies show that, the present research is a suitable base for expanding researches in future in field of system designs in a way that can be used in different wards and can provide more facilities to approach the real world
Material & Methods: the present study is applied and descriptive-analysis one which had been as the software design and data collection tool was the checklist of Booali Hospital's patients' files which its admissibility confirmed by the related experts and studied after observation, chronoscope and also time of manpower servicing to several patients and study of the nurse and doctors working scheduling with use of intelligent system's designing. Data analysis and planning is carried out with the method of Petri net and Markov and genetic algorithm with use of Matlab and Hpsim software
Results:42 % improvement in expense decreasing and 87% time saving in servicing time to patients can be seen from comparing prepared program and designed system.
Conclusion: Research various models can be used as a suitable tool for scheduling and determination staffs optimized number needed in several parts of a hospital which has a vital role. In case that the designed system in the current project is limited to the achieved and collected data from educational center of Booali attached to Tehran Islamic Azad university, it is need to make changes in programming based on data for generalizing it and optimized utilization in other hospitals. So it is recommended to make the prepared program close to the real world for make these systems utilizable in other hospitals and increasing restrictions.

Abstract
Background: The aim of this research was to measure and compare relative efficiency of general hospitals under supervision of Mashhad University of Medical Sciences (MUMS). The study also seek to investigate the likely relationship between the official evaluating scores reported by MUMS with findings of this study.
Materials & Methods: Data Envelopment Analysis (DEA) is utilized to determine relative efficiency of individual decision making units (DMUs). From state-run general hospitals in this study, 17 were selected based on the criteria suggested by the model. To distinguish efficient hospitals from inefficient ones, revised input-based BCC model was used incorporating ‘number of physicians' and ‘number of nurses' as inputs. Outputs were set as ‘the rate of inpatient days to staffed beds', ‘outpatient visits' and ‘number of surgeries' reported both at emergency and wards.
Results: The findings based on both CRS and VRS simulations indicate that the mean of technical efficiency was 0.823, mean managerial efficiency was 0.931 and subsequently mean scale efficiency was 0.881. It was further noticed that, there was no significant relationship between the performance appraisal outcomes from DEA model, and scores allocated to each hospital through official evaluation system.
Conclusion: Current official appraisal system based on pre-defined checklists may not be a reliable mean for evaluating and ranking efficiency of general hospitals.

Abstract
Background: The hospital is one of the main organizations which offering health care and medical services in a high level allocated sources in the health sectors. Therefore, considering to efficiency costs is great importance. This study aims in considering the efficiency of the hospitals of Medical University in Tabriz, Iran, by using Data Exhaustive Analysis Method.
Materials & Methods: The study inspected and analyzed the technical efficiency and also effective factors on it in selected hospitals by using Data Exhaustive Analysis Method during the 3 period years (1384-1387). In order to conduct this study, the comprehensive Input-oriented Form of Data Exhaustive Analysis Method assuming in the variable return compared with the scale. The variables of the inputs in this study included number of physicians, non-physician staff, and active bed and annual costs of the hospital. The variables of the outputs included the coefficient of the occupied beds, number of admitted patients, and surgeries. To data analyzing, SPSS and data envelopment analysis software were used. It is worth mention that the data in this study were accumulated by using the forms devised by the authors and standardized questionnaire via referring and going to the hospitals.
Results: The findings of data exhaustive analysis method showed that there was %5(TE=0/953) possible capacity augment in the technical efficiency. The findings also suggest that there is a potential frugality in consuming the inputs in order to produce a constant amount of the output. Meanwhile, there is a potential augment of the output by using a constant amount of the input, as well. The findings also represent the effect of the demographic factors and functional factors on the efficiency of the hospitals.
Conclusion: It is suggested that to leave out the surplus staff, decrease the surplus costs of the hospital through replacing the energy consumption and a proper management of energy and other surplus inputs, hire sophisticated managers and applying the graduated field of management in health care and medical services and also hire the managers with high quality degrees, create the data envelopment analysis of enhancing efficiency should be one of the useful way to provide qualified medical services in our society as a comprehensive programming. Based on the findings of the data Exhaustive analysis method, improving the efficiency of the hospitals, health care system and medical section are essential as well.

Abstract
Background: Data Envelopment Analysis (DEA) is a mathematical model that evaluates the relative efficiency of Decision Making Units (DMUs) with multiple input and output. The purpose of this paper was systematic study of applying this technique in Iranian hospitals.
Materials and Methods: In this systematic review which was conducted in September 2015 and February2016, attempted to search the research which conducted in Iranian hospitals regardless of the time of publication using searching keywords in six scientific databases and with the help of Google search engine. A total of 6,613 researches found. Then, 6,566 researches removed from the study because of the irrelevant, repetitive and Inaccessibility to the full text. Then, attempted to statistical analysis of 47 remaining researches via Excel 2010 software.
Results: 93.6 percent of the researches were published in 2009 onwards. The most research and least research have been conducted in three and eleven provinces respectively. The diversity of output indexes have been more than diversity of input indexes. In 81 percent of researches; input oriented model was used and in 74.5 percent of researches variable returns to scale is assumed. In most studies, referred to Iran's inefficient hospitals because of existence of excess resources.
Conclusions: In last seven years, the interest of Iranian researchers has increased about DEA application in hospitals especially in Tehran, Yazd and Khoozestan provinces. Scientific and rational use of resources is a proposal to the relevant authorities.

Abstract
Background: Hospitals are considered as the largest and most costly unit of the health system. The present study aims to determine the efficiency of hospitals in Mashhad.
Materials and Methods: This is a descriptive-survey study that was carried out in 2016-2017. The population of the study consisted of patients referring to hospitals in Mashhad. For data collection, records were used in hospitals and the SERVQUAL questionnaire. Data analysis was performed in soft Gams software.
Results: The results of the study indicate that in the SERVQUAL section, three dimensions of empathy response and Warranty were the most important dimensions. Also, 3 characteristics of 26 qualitative features of the service were classified as "attractive". 4 qualitative features are classified as "essential" and 16 features in "single-dimensional". The rankings obtained in the bilingual network method are approximately the same and only in the case of the last four ranks of the final ranking is done by the voting method with equal weights. And it was determined that the hospital number (3) is the lowest and hospital number (5) has the best performance.
Conclusion: By combining the fuzzy SERVQUAL method with network data envelopment analysis, we can eliminate weaknesses in the selection of indicators in different layers of network analysis and calculate the efficiency of such networks. Hospitals need to increase and plan appropriately by designing a hospital that has the highest efficiency and optimal utilization of its resources and cost-effectiveness.

Abstract
Background and Aim: Hospital is organization which its performance improvement is very important. In order to do this, we must evaluate the allocated resources and performance of hospitals. Calculating hospitals efficiency is one of the possible ways to evaluate the performance of them. In this study, the efficiency of allocated financial and human resources of public hospitals by provinces is examined.
Materials and Methods: This study was conducted in 2017-2018. Data were collected from 31 provinces of Iran. Input (including: number of physicians, number of nurses and number of active beds per ten thousand population) and output (number of hospitalizations and number of outpatients per ten thousand people). Data were collected from studies. The efficiency analyzing of the provincial treatment department was performed with DEAP software.
Results: The input population (nurse, doctor, bed) is related to hospitals and health centers in Semnan, Yazd and Mazandaran provinces And the least amount of input was related to Sistan and Baluchestan, Khuzestan, North Khorasan provinces. The highest output (inpatient and outpatient) belongs to East Azarbaijan province and the lowest output belonged to Hamedan province. Efficiency score, variable return to scale and constant return to scale for all hospitals in the country are 0.565, 0.813 and 0.47, respectively.
Conclusion: proper and correct distribution of resources between provinces may increase efficiency of resource distribution.
