Local Medical Clinic C++ Solution

 

The local medical
clinic has decided to automate its scheduling services. You have been assigned
to design the initial version of the schedules. The basic functions that the
clinic has in mind are doctor check-in and check-out and patient check-in and
check-out.

 

A doctor checks
in by telling the scheduler his or her name, an examination room number, and a
medical specialty code. Each doctor has a favorite room. The scheduler checks
to see whether the room is free. If so, it assigns this doctor to the room; if
not, it rejects the request with a message, and the doctor can try again to
check in. When a doctor checks out, the examination room is freed.

 

A patient
checking in gives a name, age, specialist code, and emergency indication. The
scheduler tries to match up the patient with a doctor according to a set of
rules that are described here. If there is a match, the patient is seen by the
assigned doctor. If this doctor is currently seeing a patient, the new patient
is queued to see the doctor.

 

The rules for
assigning doctors to patients are as follows:

•        
Any patient under age 16 is assigned to see a
pediatrician.

•        
Patients age 16 and older are assigned a doctor
according to the specialty requested. If there is no doctor in the clinic with
the requested specialty, the patient is assigned to a general practitioner
(GP). If there is no GP, the patient can be assigned to any doctor.

•        
If there is more than one doctor of the requested
specialty, the patient is assigned to the doctor with the shortest waiting
list.

 

When a patient
checks out, the doctor he or she was assigned to is available to see the next
patient, if there is anyone in the waiting list.

Input

Because this is
an interactive system, your program should prompt the users to input the
correct information. The initial prompt is

                ' Type D for Doctor or P for
Patient: '

 

The next prompt
is

 

                Type I for check-in or O for
checkout:

 

According to the
request, your program should prompt the user for any other needed information,
as indicated in the following table:

 




Action


Additional Information




Doctor check-in
Doctor
check-out
Patient
check-in
 
Patient
check-out


Doctor's name
Room number
Specialty code
Doctor's name
Patient's name
Age
Specialty (code
requested)
Patient's name
Room number




       

You may define
the format for the input processed by your program.

Output

The output for
each request is in the form of messages to the user, according to the request,
as indicated in the following table.

 




Action


Message




Doctor check-in
 
Doctor check-out
Patient check-in
Patient check-out


Confirmation that room is available or Error message if room is in
use.
Good-bye message
Message telling patient which room to go to and which doctor has
been assigned.  If no doctor is
available, apologetic message.
Good-bye message.  At a later
time we may add billing information at this point.




 

In addition to
printing the messages on the screen, you should also write the requests and
messages to a transaction file (trans.out), to be turned in with your  program listing.

Details
and Assumptions


•        
There are l 00 examination rooms at the clinic,
each with a waiting room attached.

•        
Specialty codes are as follows:

                Pediatrics                                      PED

                General practice                          GEN

                Internal medicine                        INT

                Cardiology                                    CAR

                Surgeon                                                 SUR

                Obstetrics                                     OBS

                Psychiatry                                    PSY

                Neurology                                     NEU

                Orthopedics                                         ORT

                Dermatology                                DET

                Ophthalmology                           OPT

                Ear, Nose, and Throat                 ENT

•        
You may assume that no patient leaves without
checking out.  (That is, every doctor
becomes free eventually.)

•        
No one leaves before he or she sees the assigned
doctor.  (That is, no one has to be taken
out of the waiting queue.)  The clinic is
open 24 hours a day, 7 days a week.

•        
If a doctor checks out while there is still a
waiting list of patients assigned to him or her, the patients must be
reassigned to other doctors.

•        
 

Data
Structures


The basic data
structure is a list of examination rooms with waiting lists attached to each.
Because the number of rooms is fixed, you may use an array of records to
represent it. It is the waiting list attached to each examination room that is
of interest to us. We have seen that patients are seen in the order in which
they are added to the list (a simple queue).

Deliverables

Your design including CRC cards for each class

•        
A listing of your source program including all
included files

•
