The importance of achieving an effective integration of the human operator/maintainer into the system during the system development process has increased with system sophistication and with the adoption of systems engineering as the accepted approach to system design. The shortage of qualified human factors engineers has led to the preparation of this specialized guide for the 'Program Coordinator for Human Factors Engineering'. The goal is to assist him in the management and evaluation of the contractor and in-house effort, as well as in the advice and assistances to the Program Manager. The manual consists of three parts. The first part, Volume I, is directed to a detailed review of the Navy Air Weapon Systems development process. Volume II is directed to a detailed review of specific human factors engineers' tasks in relation to the total air systems development process. Volume II contains basic reference instructions.

The Human Engineering Requirements Manual for Evolving Systems (HERMES) was conceived as a guide to the implementation and management of HFE development requirements in major Naval Air Systems Command (NAVAIRSYSCOM) Weapon System projects. It identifies major events and the coordination and interface requirements associated with the system design and development process. It also specifies inputs and outputs required in terms of purpose and function to meet the HFE objective of a totally integrated man-machine system.

A variety of human factors support services (e.g., function allocation, training system development, cockpit design) are required in the development of naval air weapon systems. For many, perhaps all, such services adequate system Functional Requirements (FRs) are a necessary prerequisite. Current practice for preparation of FRs, useful to human factors engineers, is inadequate. One solution to the problem is a manual of instructions for preparing adequate FRS. This report presents the consensus of opinion of a group of experienced system developers about what a manual of instructions for writing FRs should contain. (Author)

This document describes the Alpha-Test version of the Assessment System for Aircraft Noise (ASAN). ASAN was developed for the United States Air Force's Noise and Sonic Boom Impact Technology Advanced Development Program Office (NSBIT ADPO). The Purpose of ASAN is to provide Air Force route and environmental planners with a set tools for preparing the noise portion of environmental impact statements (EIS), environmental assessments (EA), and findings of no significant impact (FONSI). ASAN provides a consistent set of procedures and models which represent the current state-of-the-art in noise engineering practice. This report contains a brief overview of the technical issues of developing the ASAN system. A User Manual which guides the environmental planner in the use of ASAN is available as a separate volume. Keywords: Hardware considerations; Software considerations; Military training route model; Military operating area model; Human effects models; Structural damage model; Incorporation of future models.

During the system engineering process, how does one predict the maintenance Manpower, Personnel, Training, and Safety (MPTS) consequences of a proposed design before it materializes as a breadbox or mockup. This study proposes the use of a baseline comparison with an integral data base that is more sophisticated and powerful than currently available approaches. CAMT would define a set of component task primitives, each common to many maintenance tasks, associated with a common set of maintainer skill and comprehension requirements. Associated with each primitive would be immediately accessible data concerning typical MPTS resources required for adequate primitive performance on a variety of tasks and systems. Methods for task primitive definition were developed, then taken into the field for testing. Task primitives were defined to cover three remove-and-replace tasks in one aircraft maintenance field (engines). A literature review showed this approach to be unique. Future studies will address electronic maintenance, data base acquisition, and reliability of the methodology.

The Air Force is involved in research in the area of human performance and training; specifically, the interaction of human factors with the effectiveness of command and control systems. A software system which is a Capability for Evaluating Decision Aids (CEDA) was developed using the ESD CONCAP capability at MITRE. CEDA will be used by the Human Resources Laboratory for testing human performance on a tactical operations problem as the amount of information and form of presentation are varied. This document contains the specific instructions for operating CEDA. (Author)

Principal conclusions and recommendations of task 1 include: the present inability to adequately compare technical manuals from NAVAIR, NAVSEA, and NAVELEX due to differing utilizations, environments, and repair and maintenance philosophies; the lack of standardization in present funding of technical manuals (some are by budget processes, others by Navy Industrial Funding, etc); the need for technical manuals to include coverage of repair and replacement actions below the predetermined replacement level, to accommodate wartime and other conditions when replacement-level spares may be unavailable; the need for the means of funding the aforementioned coverage increment below the replacement level; and the need for a Media Evaluation Laboratory to codify the characteristics, benefits, and transformation parameters of the various media available for use in the technical manual process.

The U.S. Army Institute for Research and Management Information and Computer Sciences (AIRMICS) has conducted research in the area of human factors and the man-machine interface. As a result of this research, a pilot system for testing the adequacy of functional specifications has been developed. The concepts demonstrated in this pilot system received a favorable review by several elements within the U.S. Army Computer Systems Command (USACSC). The tasks contained in the Statement of Work of the present contract have been designed to expand the concepts of the pilot system to create a tool for use by USACSC and the Army. The Computer Aided Specification Testing System (CASTS) is a tool for the design of interactive data entry systems. The CASTS project is concerned specifically with the development of this tool. The work is divided into two processes within the CASTS system: The first process is that used by the designer to construct simulations of interactive video display terminal dialogue and the second process gathers the performance data of an actual user who runs the simulation designed in Process I of the system.

CASTS is a software system for use as a tool in the development of interactive data entry systems. It is composed of two major processes: (1) System Specification (Process I); and (2) System Simulation (Process II). The significant advantage of using CASTS is the capability for the system designer to return to the model construction phase of design to change specifications as often as necessary without major re-entry of the same information. Iterative refinements allow testing and modification of specifications without investing considerable coding effort in the initial system design process. In addition, the system designer utilizes an interactive tool which can provide valuable experience in designing other interactive systems.

This report discusses the application of system engineering principles to the development of computer programs and associated elements of large systems. Using the 'road map' approach and basic concepts established by the Air Force, it describes step-by-step events during the conceptual, definition, acquisition, and operational phases of a system life cycle. Technical milestones in system computer program analysis, design and developments are identified and related to associated activities and requirements in the areas of test and evaluation, configuration management, data management, and human factors. Procedures outlined in the guide are based on experience with a number of large electronic systems developed for the Air Force. Emphasis in the description is placed on aspects of the technical process which have significant implications for system program planning and management. (Author)
