Survey of Human Factors Methodologies and Models for Improving theMaintainability Design of Emerging Army Aviation Systems

摘要

This report presents the findings of a literature review conducted to identifyhuman factors methods and models that might be used to improve the maintainability of emerging Army aviation systems. Three methods and seven models are reviewed. The three methods are Logistic Support Analysis, Hardware versus Manpower, and Acquisition of Supportable Systems Evaluation Technology. The seven models are the Human Operator Simulator, Microcomputer Systems Analysis of Integrated Networks of Tasks, Sequiturs Workload Analysis System, Task Analysis and Workload, Maintenance Personnel Simulation, Crew Chief, and Profile. A comparison of the methods and models suggests that the Crew Chief and Profile models have the greatest immediate use for improving maintainability design. It is recommended that research be initiated that will evaluate the Crew Chief and Profile models to see if they can be applied to the maintainability design of Army aviation systems; investigate ways in which the other models might be modified and applied to Army aviation maintainer tasks; and begin a program of maintainability research to address Army aviation systems, mission requirements, and operational environments.
