A Navy surface ship represents one of the most complex man-machine systems in existence today. Performance capabilities of personnel required in the propulsion systems, weapon systems, command-control systems, operations systems, supply systems and auxiliary systems should demand that human factors engineering (HFE) receive primary consideration in the design of ships. And yet there is no formal HFE program for ship acquisition. HFE responsibilities are not integrated with each other or with ship systems engineering efforts. There is little or no standardization of HFE methods and data beyond that provided in the design work study approach. Finally, HFE has no formal status within the ship acquisition process. The Navy Sea Systems Command recently moved to correct these problems in implementation of HFE for ships. A ship HFE technology program has been established which has as its primary objectives the integration of available applicable HFE techniques, methods, principles and data into the ship acquisition process. The effort to integrate HFE technology into the ship acquisition process began with a definition of the process itself, with emphasis on the specific events and milestones within the process. The next step entailed identification of HFE requirements appropriate for each event. HFE requirements were described in terms of activities to be completed and products to be provided to the ship design effort. HFE requirements were developed for five major functional areas: manning and training, design for operability, design for maintainability, design for habitability, and test and evaluation. After identification of HFE requirements in each of these areas, determinations were made of the degree to which available HFE technologies were appropriate to satisfy the requirements. HFE technologies consisted of HFE principles, data, methods and techniques which have been reported in the HFE literature. These technology assessments represented the best estimates of the research team concerning the applicability of available technologies for specific HFE requirements.
