III. D ata Analysis and P resentation of R esults Data obtained on Arrival rate and Service Rate were computed and their performance measures were determined accordingly. Table 2 showed the trucks’ Arrival rate and the Service rate at Solous III dumpsite against the period of the day. The outcome of the relationship was plotted as depicted in Figure 1. Figure 1: Interaction between Variables of Arrival rate and Service rate Table 2: Relationship between Arrival rate and Service rate ii. Average number of trucks in the queue (no queue or length of the queue) iii. Average number of Trucks in the queue (when there is a queue) b) Time spent in the system i. Average waiting time in the queue Improving Trucks Management at Dumpsites through the Application of Queue Theory- The Case of Solous III Dumpsite, Igando, Lagos State lobal Journal of Researches in Engineering ( ) Volume XxXII Issue I Version I J G 34 Year 2022 © 2022 Global Journals a) Number of Trucks in the System i. Average number of trucks in the system ii. Average waiting time in the system (both queue and receiving service) c) Probabilities Associated with events in the system 1. The probability that a Truck will queue on arrival R = 0.96 or 96% 2. The probability that a Truck will not queue on arrival = 1-R = 0.04 or 4% 3. Probability of having exactly ‘n’ number of Truck in the system
