Applications of Queuing Theory in the Tobacco Supply

There are many problems in the supply of goods. In the company, both in the supply of goods in the form of raw materials, as well as in the supply of goods in the form of the final product to the consumer. PT XYZ obtain supplies of dried tobacco (chopped Madura) of the local name tobacco collectors as known as bandol. The queues were quite long and bandol experiencing frequent obscurity of time to be served during the waiting time shortage and obscurity. This has an impact on the cost and time to bandol. Therefore, this research aims are (1) to obtain a supply of tobacco queuing system (2) to obtain a proper queuing system in the supply of tobacco (3) to obtain a minimal cost to the queuing system in the supply of tobacco. Data analysis was performed according to the queuing models in the PT XYZ. The results of the study are (1) queuing systems in the form PT XYZ path queuing system with a multiple channel, the waiting time to be served short enough that 0.003 minutes, the average time of 2.877 minutes in the system, the queue length 0.0006 unit of transportation service is equivalent to one unit of transportation, long queues in the system are 0.605 units of transportation that equal to 21units of transportation (2) the actual occurrence of a long queue outside the queuing system, because the transportation carrying tobacco wants to earn their turn to enter the warehouse and immediately served (3) minimal costs for bandol incurred amounted to Rp 450,000.00 for one unit of transportation (pick up) that it brought 2 workers. Minimal costs incurred amounted to Rp 700,000.00 for other unit of transportation (truck) that it brought two workers to the difference in labour and rental costs.
