- Assigning patients to healthcare centers using dispatching rulesPublication . Teymourifar, Aydin; Trindade, Maria A. M.This study proposes a model for the balanced assignment of patients to healthcare centers in a region. In the suggested model, it is supposed that patients want to go to the nearest center, which causes an imbalance in the workloads of resources between centers. This disproportion is undesirable not only for the centers but also for the patients. Thus, balancing assignments is targeted. This goal is expressed in a model with a multi-objective function. Since balancing is one of the main goals of the sectorization concept, we characterize the model based on it. Unlike studies in the literature, we do sectorization employing dispatching rules. This diminishes the problem's complexity and makes it suitable for solving actual, large, and dynamic problems. We simulated the system using the Rockwell Arena software. We consider the effect of different seasons, days, and hours on the system. The dispatching rule used for sectorization is optimized using the OptQuest software. The numerical results demonstrate that by optimizing the dispatching rule, it is possible to enhance the objective function significantly.
- Dynamic resectorization to improve utility of healthcare systemsPublication . Teymourifar, Aydin; Trindade, Maria A. M.This study discusses a regional healthcare system including several hospitals with different characteristics. We define a utility function for the system based on the sectorization concept to form a balance between hospitals in terms of important outputs such as waiting times and demands. Since the determined system is dynamic, the balance state is lost over time; consequently, resectorization is done over time. We simulate the system utilizing the data of a case study. We characterize multiple periods and calculate the utility of the system's current state. We design resectorization scenarios based on boosting the capacity and quality of hospitals. Numerical results demonstrate that substantial improvement of utility with resectorization is achievable.
