| Known as cities of metropolitan, majority people in Jakarta cnsidering time as one of the important aspect in their daily life. If there is a delay lot of losses such as loss of time and opportunity to carry out other activities, the decline in revenue, reduced harmony with others, the cancellation of the agreement also could affect up to loss of livelihood. Therefore, researchers are trying to provide a solution to problems of this queue. Queue system as research object is a queue system Roxy Pharmacy located in Mangga Resar West Jakarta Queues pharmacy is meant queuing system used in managing the patient's pharmacy at the time of receipt of a prescription, payment at the cash register and taking medications, to keep things running more smoothly than the patient, as well as the management of pharmacies that serve patients. Tn resolving this issue researchers will use operations research methods through queuing theory and will try to propose improvements to try a wide variety of other forms of queuing systems using system simulation Promodel. By the time researchers using queuing theory, the researchers will use the formulas in the course of the work while in the simulation nrocess researchers will be elued to the nrincinle of trial and error to create a model that is closer to reality. In prsoes simulation researchers will be confronted with models of the queue to be determined. Errors detennine the method results in studies conducted can not be used to repair existing queue system |
