Abstract :

This paper is a comparative study of ticket service facilities at subway stations with single and multiple queues. The ticket service facilities at subway stations are a unique queuing systems of which inter arrival interval and service time are Phase Type (PH) distributed with multi servers and queues that can either be single or multiple. The PH/PH/1 and PH/PH/C queuing models are used evaluate multiple and single queues ticket service facilities respectively. The study showed that ticket service facilities with single queues perform better than the ticket service facilities with multiple queues. Also, the PH/PH/1 and PH/PH/C queuing models are compared with the expositing M/M/C and D/D/C queuing models for the assessment. Thus, this study provides guideline to the subway station planners and designer to evaluate the subway station service facilities more efficiently and design intelligently.
