 Now we see that we can´t solve problem of waiting time very effectively in real.
-The big problem is beginning in the morning. Patients usually start comming at 7:00 and doctors start working at 9:00. There are 2 hours at least when patients have to wait. In both experiments there is maximum count of patients in system around 24 of standard patients, 6 seriously injured patients and around 7 hospitalited patients. Maximum number of waiting patients for examination is in case of standard patients around 23.

Maximum number of waiting patients for examination is in case of standard patients around 23.
 There is the difference in waiting time between 4 and 2 working doctors in medical staffs. The waiting time is half. But when we count the salary of one doctor (in average around 40 000 -45 000Kč/month) there is situation which is not so economic.
 There are limitations as number of staffs in hospital too.

-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.

 Hospitalized patients have no other branch off.
 Standard patients are coming from outside of hospital and there is one branch off which is divided by percent.  It is  because of there are 9%of patients who don’t want to wait and leave the waiting room before an examination by doctor. Other 91% are waiting for an examination by doctor.
 <div>''Examination by doctor''</div>
 This part of simulation simulates examination or treatment by the doctor. It is illustrated by normal distribution Nor(10.0, 3.0, 1) in minutes. In the next step after examination by the doctor it is decided if a patient needs another examination (for example CT, X-ray, MR or other blood tests. There are usually 30% of patients who need another examination. 55% of patients are sent home. And the rest  (15%) stays in the hospital and are hospitalized.
 <div>''Other examinations''</div>
 This simulates other examinations which are needed for right decisions of a doctor in the office. There is used exponential distribution Nor (15.0, 3.0, 1) minutes. After this patients can be sent back to the waiting room (95%), or  can be sent home (5%) because  results will be known after 20-23hours.  These patients go home, but there are 2% of them who don’t come back to get  their  results. The rest  (98%) comes back for their results.  The distribution of the time when they come back is given by triangular distribution Tri (22.0, 23.0, 23.5).

 =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.

 <div>'''SeriouslyInjuredPatient''' – this is a seriously injured patient with the priority number one. It means that he is preferred over  other types of patients. This entity is generated in Poisson distribution (2.0) a day in time 9:00-16:00. Outside this time people visit emergency staff. </div>
 <div>'''HospitaledPacient''' - this is a patient which is coming from the same hospital. He is prevailed over the standard patient. he is known to the doctor, because he usually has got accompaniment from the hospital. These patients usually come  in the  morning between 7:00-11:00. Poisson distribution for this time is Poi (2.0) for an hour. In time 11:00-16:00 there are  noticeably fewer  patients. Poisson distribution for this time is Poi (1.0) for an hour.</div>
 <div>'''StandardPatient''' – this patient is coming from the outside of hospital and his injury is not extensive or he has any other non-serious problem (at least he doesn’t know that it is serious, he has no large bleeding e.g.). These patients are coming usually between 7:00 and 11:00. Poisson distribution for this is Poi (6.0) for an hour. In the  afternoon (11:00-16:00) around 3 patients  come Poi(3.0) in  an hour.</div>
 <div>Explanation of other situations: The simulation doesn´t take into account   patients attending the medical office on Saturdays and Sundays, because on weekends patients  usually attend emergency departments  because they know the medical office is closed.</div>
