- چکیده:
- چکیده انگلیسی: Nowadays, hospitals are seeking to reduce their costs and to improve their financial circumstances. They are looking to reach the highest level of patient satisfaction as well. Operating rooms are one of the most critical departments and a great source of income in hospitals. In this research, an operating room scheduling problem is studied, which considers patient priorities based on a real case study. The problem comes from a medium-size private hospital in the north of Iran. To tackle this problem, a mixed-integer-program model is presented. The model considers the hospital’s resources and constraints as well as patients’ priority according to their age and the type of operation they need. In this model, assigning elective patients to operating rooms and the sequence of patients' surgeries have determined to minimize the surgeon waiting time as the objective function. The model is implemented in Cplex 12.9 software, and the efficiency of the model is shown by comparing the obtained results with the current situation. Real data of one week from the hospital is used to prove the efficiency of the model. Analyzing the results show a 35 percent improvement compare to the hospital's current scheduling method.

- چکیده:
- چکیده انگلیسی: The purpose of the present study is to investigate the effect of behavioral variables on overconfidence in management, herding behavior and investors' emotional tendency on stock return. To this end, by using the data of firms listed in the Iran's Stock Exchange during the seven-year period of 2010-2016, overconfidence index in management, the herding behavior of the investors and the emotional tendency of the investors were calculated and their impact on stock return was examined. The data of the research are of a panel type and for analyzing the data and testing the hypotheses; a multiple linear regression model has been used. Evidence from the experimental results of the research showed that the behavioral variables studied in the research has a significant and inverse effect on the stock return of the companies.
