Abstract

Modeling and simulation are widely used in many business domains, such as logistics, manufacturing, warehouses, and hospitals. This research used discrete event simulation (DES) combined with agent-based simulation (ABS) to improve draftees' physical examination service by reducing their process waiting time. A computer simulation was developed to simulate a physical examination center that serves a person conscripted for military service. The waiting time before and after applying the proposed approach was compared. Data were sourced from the physical examination center admissions database and field observation. The computer simulation model was validated by comparing the simulation results with waiting time, throughput time, and doctors' utilization obtained in real operation. The experimental results showed that the combined DES and ABS model reduces waiting time by an average of 40.15\% in waiting time by using the same resources. Thus, using the correct simulation model significantly reduces draftees waiting time in a physical examination center. The proposed approach can reduce waiting time in an examination center and can be applied to any physical examination process.
