The aim of this paper is to model and simulate the ophthalmology service of Regional Military and University Hospital of Oran (RMUHO) in Algeria using ASDI methodology (Analysis, Specification, Design and Implementation). Ophthalmology is a medical science apprentice of anatomy, diseases, vision disorders, eye therapy and its annexes. The ophthalmology service is an essential unit and occupies an important place in hospitals. This study focuses on the functional exploration of the ophthalmology service and mainly on the simulation of units for consultation, examination and care. The objective is to study the utilization rate of rooms and doctors of ophthalmology service, and to increase its quality of service. For this, we first use the ARIS tool to specify the knowledge model and then we simulate models thanks to the SIMULA language and the Witness tool to implement action models. We have thus completed the transition from a knowledge model to action models. We obtained simulation results that we discuss and we propose an enhancement of the appointments process.
