PORTSIM v.4.3 : user's manual.

This manual documents the capabilities and functions of the Port Simulation (PORTSIM) Model, Version 4.3, which operates on Windows NT 4.0 or Windows 2000. Step-by-step procedures for using PORTSIM are provided. PORTSIM is a discrete-event simulation model that allows for a comprehensive analysis of all critical seaport operations for embarkation. It is applicable to ports worldwide. This simulation system addresses the complexities of port operations and gives you a way to measure the desirability of any given plan of action. PORTSIM models all cargo items, ships, and port infrastructure resources as individual objects. A typical scenario may process more than 10,000 cargo items. Cargo is simulated from the time it arrives at a port to the time it is loaded onto a ship. Note that PORTSIM Version 4.3 models only embarkation activities. Modeling of debarkation currently is being handled under another software framework. You can use PORTSIM to specify the availability of port resources to provide the most realistic simulation possible. The simulation provides detailed information on cargo throughput and infrastructure utilization. With PORTSIM, you can simulate the movement of entire military units through a specified port. You can also selectively constrain resources or operational parameters, to identify potential bottlenecks. To support your analysis, the software provides utilization statistics for all port resources (e.g., gates, staging areas, interchange yards, berths, inspectors, and container handling equipment). Simulation results are presented in three ways. (1) During the simulation run, utilization information is presented graphically in real time as continuous display meters that can help you monitor activity and identify potential problems visually as they develop. (2) During the run, you can also view a summary screen showing the current status of transports and cargo. (3) After the run, reports and graphs showing the final results can be viewed and saved
