Modeling patient flows is an important modeling; issue, providing healthcare managers with information; regarding the resourcing requirements during the planning; phase of new healthcare facilities, as well as the performance; evaluation of existing facilities. This paper develops a generic; model of patient flows in a progressive patient-care system; based on colored Petri nets. The model is developed at two; different levels of detail. At the higher-level is the flow of; patients between different units. At the lower-level is the; functioning of the individual units which gives rise to the; higher-level behavior. Each individual unit comprising the; system is represented as having a generic structure with; patient length of stay and admission rates modeled as random; variables for different types of patient. The model proposed; here improves on previous models of patient flow in terms of; flexibility, extensibility, and the range of performance; parameters it is able to generate.
