Abstract

This study aimed to present a descriptive account of the queueing system at the entry gates of the International Container Terminal Services, Inc. (ICTSI) at the Port of Manila. The data were collected from January 4 to 10, 1991 at the East gate 4f Subsequently, several features of the queueing system were identified. Thus it was noted that the container trucks had single-arrival pattern of service. It followed the First Come, First Serve (FCFS) queue discipline. It can further be described as infinite, single -channel and with multi-stage type of service. Eased on the results of the Chi-square goodness-of-fit tests on the data, it was established that the arrival and service time distributions follow the assumed theoretical Poisson and exponential distributions, respectively. The queueing model (M/M/1) : (FCFR : o/o) was then applied to compute measures of performance. It was found that for the export lanes, Monday and Tuesday are lean days, while Wednesday to Saturday are peak days. For import weekdays are the peak days, while weekends are lean days. Service rates do not vary significantly. Hour 6 (1-2 pm) of the peak days for export lanes was found to have the highest utilization factor (p=r/m) of 1.2530 > I which means that arrival rate is greater than service rate, On the other hand, hour 1 (7-8 am) of the same day had the lowest utilization factor of 0.0152 <1 suggesting that arrival rate is less than service rate.
