Modeling the wait time of a hierarchical system: Case study of an Internal Medicine unit

All, such as industrial production (Manufacturing companies), health units are hierarchical at the level of organization. This arrangement permits them to response efficiently to an event in occurrence, such as a patient whom appropriate care has to be dispensed. The quick reaction of the medical unit when faced with a problem is not only an indicator of its reactivity, but also an indicator of its performance. In this article, we propose to model the reaction of a medical unit in relationship to parameters, notably the reference periods of the different levels at which decisions are made. We define and express subsequently, the wait times which is a source of delay in the treatment process of a patient from when he arrives. Then, we propose an algorithm which minimizes the wait time.
