Health care systems are among most important service centers in every society because they directly deal with human's life. Among manifold different kinds of health care systems, emergency services are the most significant ones. Increasing costs of the system is the most important problem of emergency services all over the world. These high costs have resulted in low quality of the service. So, proposing an effective plan for decreasing the costs is severely needed.
In this research, initially a long term and strategic plan is offered for emergency capacity in a determined period of time. In this plan, total costs of system including capacity as well as waiting time of patients are... 

Outpatient clinics always encounter a huge deal of demand and due to the variety of the services they provide and the existence of uncertainties, operation management is such a difficult task. This issue has made problems related to this issue popular among scientists and researchers. In this research, we are going to address several popular problems related to outpatient appointment scheduling. Initially, an M/M/c/K queuing system is developed in order to obtain the optimum scheduling window for different sub clinics. Secondly, the real demand for each sub clinics will be estimated using data analysis techniques for each 24-hour period. Having the results of the previous section, we build a... 

The outpatient clinics have some features that make them different from other types of the clinic. Something that must be paid attention is adherence to appointments by outpatients, which have an undeniable effect on the productivity of the Outpatient Appointment System. In most of the outpatient clinics, outpatients are supposed to schedule their appointment in advance. As a result, if patients do not come to the health center based on their scheduled appointment, and they do not inform the health center about their absence, not only will the clinic become deprived of the opportunity to utilize its resources efficiently, but also healthcare access for other patients will reduce. The rate of... 

Patient scheduling is one of the most important problems in healthcare optimization which has been in center of attention in various environments including outpatient clinics and operating rooms. Effective scheduling systems have the goal of matching the demand with capacity so that resources are better utilized and patient waiting times are minimized. Furthermore, patient scheduling can be merged with another problem in which the main goal is to find the optimal sequence of a given list of patients. Moreover, there are several sources of uncertainty such as patients’ unpunctuality, absence, and service time in this problem resulting in having a very complex problem. In this research,...
