Purpose: High efficiency in the operating room may significantly improve the overall performance of the hospital and the service quality provided to patients. The operating room is the de facto financial hub of the hospital and maximizing its efficiency may lead to considerable improvements. To this end, we seek ways of accelerating the patient flow in order to save time and cost in healthcare facilities.Methodology: In this study, we use agent-based simulation to simulate patient care in the operating room. After performing the required validations, a number of improvement scenarios were developed and evaluated.Findings: A hybrid scenario including modifications to the referral time of the patient by the surgeon, transfer time of the surgical set and supplies to the operating room, and the timing of anesthesia proved to have the most positive impact on the criteria i.e. activities, reducing the average Length of Stay (LOS) by 9.69 minutes. The second-most effective scenario involved modifying the referral time of the patient by the surgeon, reduced the LOS by 7.31 minutes.Originality/Value: Through this research, it became apparent that minimizing the patients' LOS improves the efficiency of the operating room as it helps reduce the overall idle time and increases the number of operations carried out in each shift. Making time even for one additional operation per day significantly increases the operating room income. Moreover, a shorter LOS means less fatigue for the medical staff and reduces the total cost of running the operating room by reducing the staff's overtime hours.

Purpose: It is clear to everyone that in this period, one of the key factors of economic growth of countries is the knowledge-based economy, and in the meantime, the existence of knowledge-based companies forms the main infrastructure for achieving this important goal. This article was conducted with the aim of developing knowledge-based companies with an emphasis on their business processes.Methodology: For this purpose, business processes were reviewed through a literary review and due to the comprehensiveness of the EFQM model, it was selected for further review. Then, 9 companies were identified as targets, located in the organization's growth center, interviews and the injuries of these companies were identified. Then, decision-making and coordination mechanisms according to the integrity of organizational processes, programs and approaches of large companies in the Excellence Award statement of the organization were reviewed and the approaches used by these companies were extracted and categorized. In this way, the opinions of experts in this field were used to adjust the programs and approaches. Finally, a model based on system dynamics was designed to investigate the key processes of acquiring knowledge-based businesses.Findings: Since increasing the score of EFQM model is considered as increasing the probability of company growth, so it is possible to use this model to provide solutions for the growth of knowledge-based companies.Originality/Value: In this paper, simulation and mathematical models are used to develop the performance of knowledge-based companies and simultaneously analyze the damage of companies and compare it with a comprehensive model, so that appropriate solutions to improve processes can be predicted.
