Thanks guys, I've got the program working now without errors coming up. A queue forms whenever existing demand exceeds the existing capacity of the service facility; that is whenever arriving customers cannot receive immediate service due to busy servers. If the Queue has a task waiting, the Server takes the task and processes it. What this means is that you can download and try out LogixPro 500 in a 15 day Trial Evaluation mode, and make up your own mind as to whether it's the most advanced PLC Simulator and best training value on the market today.

G/G/1 Queue Model Simulation in Java In this post, we present an object-oriented design and implementation of an event-driven G/G/1 queue model simulation using Java. Queue implementations generally do not define element-based versions of methods equals and hashCode but instead inherit the identity based versions from class Object, because element-based equality is not always well-defined for queues with the same elements but different ordering properties. Commonly used queue disciplines are: FIFO - Customers are served on a first-in first-out basis. A single server queuing system can tell us the following things-How many times a user need to wait in waiting & Total waiting time; How many times user take in service time & Total service time. 2) Stochastic Processes, Markov Chains etc. Examples: airline checkin, doctor’s o ce, restaurant.
