Altiok / Melamed Simulation Modeling and Analysis with Arena Chapter 12 2 Examples of simulation modeling and analysis projects for transportation systems include designing new traffic routes and alternate routes to satisfy demand for additional road capacity eliminating bottlenecks and congestion points in existing routes by appropriate placement of traffic lights and tollbooths designing traffic patterns on the factory floor, including transporters and conveyors, for efficient movement of raw material and product designing port facilities, such as berths and piers, and allocating vessels to berths, where such designs include material handling systems (loaders/unloaders, transporters, conveyors and others) for containers and bulk material transport designing new airports or adding runways to existing ones to satisfy demand for additional flight capacity, where such designs include air traffic patterns and routing, runway scheduling and planning cargo operations Examples of Transportation Systems

Altiok / Melamed Simulation Modeling and Analysis with Arena Chapter 12 3 The panel supports modules that provide additional mechanisms of time-lapse transfer of Arena entities among Station modules or geographic locations Route modules may be used as dispatch points, and Station modules as destination points Transporter and Conveyor modules may be used for material transport the Enter and Leave modules may be used to transfer entities into and out of physical or logical locations the PickStation module allows entities to select a destination Station module using a selection criterion, such as the minimum or maximum of queue size, number of busy resource units, or an arbitrary expression alternatively, an entity can be endowed with an itinerary using the Sequence module to specify a sequence of Station modules (referred to in Arena as Step objects) Advanced Transfer Template Panel

Altiok / Melamed Simulation Modeling and Analysis with Arena Chapter 12 4 A Station module is used to designate a physical location or a logical location in the model example: a physical location might be a milling station that physically houses milling machines example: a logical location might be a dummy station at a model site close to a cluster of related modules A Route module is used to route (transfer) entities to Station modules at various locations in the model the destination Station module may be specified in an entity attribute as an expression, as a Station module name, or as part of an itinerary defined in a Sequence module Route modules are not graphically connected to destination Station modules Station and Route Modules
