Activity Model: Ship Repair and Conversion



Yung-Tsun Lee, Swee K. Leong, Charles R. McLean


This document presents an activity model that identifies the functions involved in the ship repair and conversion industry, and the information flows required to perform those functions. The activity model presented in this document is using the Integrated Definition for Functional Modeling (IDEFO) methodology. The document also includes two appendices: a node tree that describes functional hierarchy, and a glossary that provides definitions to all terms, including activity names and data/objects, used in the activity model.
