    This paper deals with the extended model of double ended queue. Conventional double ended queue model assumes that one demand requires one supply and the pairing time is instantaneous when they are pairing. The inter arrival time is assumed that its distribution follows exponential distribution and only one entity is allowed to enter the system. But there are cases that multiple bulk entry arrives at the system and the inter arrival time does not follow exponential distribution. The size of pairing can be multiple or a random variable, and the pairing time may not be instantaneous. Moreover the pairing is not always successful. A simulation algorithm is developed to overcome such difficulties due to the restrictions of theoretical method. The system patterns are compared after finding the system state probability and performance by varying several input factors affecting the system. A port service facility is demonstrated to show a numerical example. To implement the simulation model Promodel simulation software is used and Simrunner optimization tool is used to find the optimal system outputs.
