PURPOSE: A customer request and functional requirement analysis method for a GIS based dock and quay simulation is provided to have an independent framework structure from an application system, thereby developing customized processes and a GUI which are familiar to a field operator and appropriate for an environment of a ship and offshore industrial company. CONSTITUTION: A simulation engine calculates and analyzes a simulation according to interactions of kennels which are interpretation and analysis modules including mathematical calculations. A visualization engine displays a visualization object, which is calculated by the simulation engine, from an identical customer point of view. An analysis ensign provides a display function about analysis results of the simulation engine and utilizes the results calculated by the simulation engines as output data in a neutral form.
