Port Operational Performance Simulator (POPS). Version 1.0. User's Manual
Abstract
The Military Traffic Management Command Transportation Engineering Agency (MTMCTEA) developed the port operational performance simulator (POP) computer model to assist planners in estimating the cargo throughout capability of marine terminals. The model yields throughout capability values for three transportation subsystems - shipping, staging, and terminal processing (car reception or clearance) - in terms of STON and MTON per day. The procedure used for estimating capability is based on a weak-link analysis, in which each subsystem is analyzed separately and then compared to find the least capable subsystem. Since the output of the port can be no greater than that of the limiting subsystem, the weakest subsystem defines the maximum throughput capability of the terminal. The throughput capability of the port can be determined by summing the capabilities of the weak-link subsystems of each terminal comprising the port complex. Specific estimates of marine terminal capability apply only to a very narrow set of conditions and operating parameters. The throughput capabilities of terminal subsystems are significantly impacted by several factors unrelated to terminal characteristics. Since factors include the class of cargo, type of ship, and mode of land transportation. Since these factors change continuously, average values related to specific transshipments must be used in calculating the average long-term throughput capability of marine terminals.
