Abstract
  • The increasing level of complexity in systems creates a growing challenge for engineers to design safe and reliable systems. The growing complexity can lead to possible moments when situations occur that were unanticipated or were not known that they could occur by designers and leave the system in an undesirable state. This may happen if system designers were unable to identify the failure state or if they failed to pass on known information to other designers. This research aims to provide a systematic approach to identifying failure states in complex systems and to improve the connection between the different sides of development of the system by proposing a methodology of investigating the failure states. The methodology identifies potential failure states as a system executes a command and has designers examine them to make recommendations into the severity and potential solutions to the failure state. The information is organized into a single table that is passed over to other system developers and used in the design of the other sub-systems. The table also serves as a record of the analysis that can be used for reuse or future redesigns. The benefits of the methodology are examined using the K10 rover developed by NASA as an example. The K10 rover is analyzed to identify its failure states as it executes a command. The identified failure states are analyzed and the information gained is used to classify the failure state according to a ranking scale developed for this research.
