• Software used: SimProcess

Problem definition

In this simulation the medical office in the real concrete hospital is simulated. Because in this medical office there is a long waiting time, it is necessary to optimize the number of doctors. After this optimization a patient doesn’t have to wait for more than half an hour. The goal of the simulation is to model a real process of patients waiting for examination by doctor. The main experiment shall determine how long a patient has to wait in the waiting room until he is going for the examination by doctor. If we want to make this situation real , there must be simulated other aspects, for example an examination, patients which are coming from an examination and other real situations which extend the patient waiting time.

Method

Although the simulation can be solved by other methods, it looks like a good idea to solve it with SIMPROCESS. Process in this simulation tool is clearer and simpler than in other simulation tools like Netlogo. Simulation can be illustrated in simple processes. Because there was used a trial version of SIMRPOCESS, there are some limitations, e.g. in number of entities or resources.

Model

This model of simulation is divided in three main processes. These three processes are “Incoming patients”, the complex process “Examination” and the simple process “Going home“. The illustration below depicts a patient moving to the examination by doctor in his office. A patient could be sent for the examination, stay in hospital, or he could be sent home for waiting for results. .The model is based on real numbers from the hospital information system and on information from employees who work in this part of hospital.
