PENGEMBANGAN MODEL ANTRIAN PADA STASIUN TIMBANGAN TEBU DI PG PANDJIE SITUBONDO
ABSTRACT: Research was aimed
to develop the cane-scale queuing system at PG Pandjie, Situbondo, and to find
good solution to fix the waiting line problem.
Based on this research the queuing model that used in cane scale is
(M/M/1):( FIFO/∞/∞) with arrival rate (λ) 84 truck/hour, service rate (µ) 39
truck/hour, and average waiting time in the system is 7 hours and 3 minutes. To
improve this system performance, there are 3 alternative, first alternative is
to decrease the service time. Therefore,
the service rate will increase to 45 trucks per hour. This alternative will
decrease average waiting time in the system to 5 hours 45 minutes. Second
alternative is to add a service facility. This alternative will decrease
average waiting time to 47 minutes. Third alternative is combining the first
alternative and second alternative. Average waiting time in the system
decreases until 11 minutes if this alternative is implemented. Based on utility
factor and probability, costumer must wait.
The best alternative to solve the waiting line problem in cane scale
station is third alternative. This is
due to this alternative has utility factor that equal than 1 and the
probability for costumer to wait is smaller than the other alternative.
