Functional Modelling, Scenario Development, and Options Analysis to Support Optimized Crewing for Damage Control. Phase 1: Functional Modelling

Abstract : The Canadian Navy hopes to achieve significant lifetime cost reductions by implementing optimized crew levels across its next-generation fleet. Defence Research and Development Canada (DRDC) has recognized that optimized crewing can only be achieved through a thorough Human-Systems Integration (HSI) effort, and that this effort will require systems modelling techniques to help the Navy predict the effectiveness of technologies and work strategies that aim to reduce operator workload and improve mission success. This report describes the first phase of a project undertaken to provide DRDC with such a technique, and details the development of an Abstraction Hierarchy (AH) functional model of the domain of damage control. Two subsequent phases of analysis are planned: to develop damage control scenarios, and to identify emerging damage control technologies and the reduced crew levels required to support them. These will be used as inputs for a follow-on project to develop a simulation of human and automated work in the damage control domain. The AH model documented in this report is a strong basis for the subsequent phases of this project, and the follow-on simulation development effort.
